You hold in your hand a new issue of ABSPartners, where as usual you will find case stories,applications and interesting pump, mixer and

aerator installations from all round the world.The magazine also covers a lot of different

areas, with everything from water and wastewatersolutions, various industries, such as pulp &paper, oil and automobiles, and constructionprojects of large dams and tunnels.

Several of the articles in this issue cover theenvironment. This is, of course, natural whenyou supply products for water and wastewatertreatment, and are involved in solutions thataffect the development of communities and evenchange the lives of people.

Some discouraging information on this

subject can be found in the article on pages 6 7.For example the fact that almost 1.5 billionpeople in the world live without clean water,and that over 2 bil lion people stil l do not haveaccess to satisfactory wastewater treatment.

These facts are a challenging responsibilityfor any company involved in this area. It makesyou realise that the whole environmental issuecovers so much more than just havingenvironmental-friendly production with focuson sustainability, energy-saving and reliableproducts, and a strong environmental awarenessin general.

What we, as a company, always strive to dois to follow the policy of cost-effectivepumping. In this concept, we include theentire idea of Life Cycle Cost with itscornerstones reliability and efficientsolutions over t ime. As an example, on page10, you can read about sewage treatment inPrague, where the agitator solution saves thecity 30,000 EURO annually per digester.

We will continue focus on developing andoffering environmental-friendly solutions thatprovides the lowest possible LCC, to all cornersof the Earth.

Located in the south-east corner of theprovince of Leinster, the county ofWexford has an area of about 2,000 squarekilometres and a population of 110,000people. The county seat has 20,000inhabitants while the rest of thepopulation lives in smaller towns or

in rural areas.The scattered population means

that a large number of pumpingstation needed many with pumpsin the 2 kW to 6 kW range and DN100 discharge sizes.

RELI ABLE OPERATI ON

IS CRITI CAL

A key element is the fact that mostof the stations are unmanned andmust function reliably with onlyroutine maintenance. From a

perspective of both cost efficiencyand social aspects, the ability tooperate without blockage is critical. Nobodywants to be called out in the middle of thenight to clear a blocked pump in a sewagelifting station.

Indeed, it has been calculated thatthree or four call-outs would equal the priceof the pump! says Executive Technician

Patented for the first time over 30 yearsago, the ContraBlock system has beencontinually developed and improved,giving it a unique posit ion in blockage-freepumping.

FI ELD AND CLOGGI NG TESTS

The new ContraBlock system has gonethrough field tests at various locations inEurope, the USA and Asia. Extensivelaboratory tests, including witness cloggingtests by the well-known test institute LGAin Germany, have also been undertaken.

Among the items tested were towels,cloths, rubbish sacks, hygiene articles, plasticbottles and shoes. The tests showed not onlythat the pumps did not block, but that thepumped articles were not cut up they hadonly a small amount of wear and tear, andwere easily retained by a screen typically

located at the inlet to a treatment plant.

EFFI CIENCY TESTS

Tests have also been carried out to measurethe efficiency and clogging characteristicsof various types of hydraulics used in sewagepumps.

The province of Leinster, Ireland, has solved its problems with

blocking pumps:Thanks to the ContraBlock, we have a dramatic reduction

in call-outs says Ed Bolger, Executive Technician of the Environ-

mental Department.

Trouble-free Pumping ABS launches theNext Generation

Blockage-free operation has alreadybeen proven in more than one million

installations world-wide.ABS is now launching the Next

Generation of the ContraBlock, witheven higher efficiency and improvednon-clogging features.

with ContraBlock

The ContraBlock acts

as an anti-blockage devicewith an open single or multi-blade impeller revolving on a

spiralled groove, ensuring thatsolids or fibres are transportedthrough the pump without blockage.

The freedom from blockage plus the highhydraulic efficiency provide us with thelowest life cycle cost Ed Bolger explains.

BLOCKAGE

In one partic-ular examplein the resortarea of Ross-lare, there wasa problem withcontinuousblockage oftwo 3 kWclosed singlechannel pumps.The countyc o u n c i l

replaced themwith two

ContraBlockTM models from ABS, AFP1041 M30/4 which are DN 100 pumpswith 3 kW motors.

Not only was the blockage problemsolved, but also the pumped volume im-proved due to the effective sealing methodin the pedestal design, Ed Bolger explains.

DURABLE EF FICI ENCY

The county council had used a numberof various pumps over the years, but

learned from experience that the ABSContraBlockTM system was the mostreliable,Bolger adds.

The ini tial efficiency is high, and thepossibility to easily restore efficiencythrough the adjustable wear plate makes

it also a durable solution over time.Thefreedom from blockage plus high hydraulicefficiency provide us with the lowest lifecycle cost, Ed Bolger concludes.

The tests were done with singlechannel, twin channel (both closed andopen), vortex, cutter and ContraBlock

impellers for DN 100 to DN 150 pumps.The test results showed that the Contra-

Block system had the best combination

of resistance to blockage and efficiency. TheContraBlock system is available in variousdischarge sizes from DN 80 to DN 300on pumps from 1.3 kW to 100 kW.

Haindl Papier:

H aindl began using recycled paper asraw material as early as the thirties.The technical break-through came in 1962,when one of the Haindl mills launched oneof the first de-inking lines (for removingprinting ink from paper) in the world.

A main part of the companysresearch has since then been focused on

various aspects of recycled paper, such asusing recycling even in high quali ty paperproduction.

One example is the Haindl mill whichproduces paper containing of 100%recycled paper for printing dailies . Thecompany estimates that about 900,000tonnes of wood (dry weight) are savedannually thanks to this recycling method!

NEW PAPER MACHINE IN AUGSBURG

In order to enhance the recycling paperconcept even further, in 1999 Haindl

invested about DM 800 million in a newpaper machine, PM 3, in Augsburg, Bavaria.The machine has been labelled The mostmodern and innovative paper machine inthe world.

Some data about the impressive machineproject says that 200,000 man hours wereused for research and development and thatmore than 40 people were members of the

project team. Furthermore, about 1,000people were involved in building andinstalling. The total weight of the machineis almost 6,000 tonnes, the central cylinder

of the press section weighs 93 tonnes andthere is a total of 10,000 control circuitsfor machine control.

The machine went on stream inJune last year and is now producing 400,000tonnes of LWC-paper a year, the highestq u a l i t yamong the

m a s sp r i n t i n gpaper forcataloguesand jour-nals.

PUMPS

AND

AGITATORS

FOR PM 3

A lot ofpumps are

needed tofulfil all requirements for liquid transportand handling in a paper mill, and ABShas supplied nearly 1,000 pumps to theHaindl Group over the years.

For the new paper machine, morethan 180 process pumps have beeninstalled, all made of stainless steel.

Each type of liquid require its specialpump type: for stock, ABS BA pumps areused, for diluted stock NB pumps, andfor contaminated liquids the FB pump isthe best alternative. To complete the

picture, a large, horizontally split,double-flow Z22 pump wasinstalled in the water treatmentsection.

37 SCABA side entryagitators were also delivered for thePM 3. The agitators were selectedthanks to their guaranteed qualities interms of energy consumption andsedimentation. Another positive feature isthat its possible to overhaul the agitators,even when the tank is full.

SEALING RELIABILI TY

Sealing the pump shaft is of vitalimportance to the reliabil ity of the pump.Haindl Papier selected various seal types

In 1999, Haindl Papier GmbH in Germany was awarded the European Recycling Award for

their innovative work with recycled paper and product intregrated environmental protection.Even the new PM 3 machine at the Augsburg mill, called the most modern paper machine in

the world, is part of an environmental policy which involves the whole Haindl Group.

to get the best result: dynamic seals,double mechanical seals and single seals,depending on the application. Allmechanical seals were built into service-friendly seal cartridges.

Special measures were taken toreduce thecosts of en-

ergy andwater to theseals, withouta f f e c t i n gpump relia-bility in anyway.

NE W

CONCEPT

Additionalsavings wereachieved in

using thenew, free-standing baseplates of theSystemPMI, Pump Mill Integration.

All pump units of the PM 3 projecthave been mounted on heavy concretebaseplates, positioned on stainless steelpads which stand free on the floor.

As no planning or work connectedwith fixing and grouting of baseplates wasneeded, both time and costs were savedwhen these units were installed. Thesolution with pump, motor and baseplate

as a free-standing single

unit also minimises theeffects of pipe strain andstresses on alignment,which means that costlymaintenance anddowntime can then be

avoided. Furthermore, afree-standing installation minimises theeffects of vibrations and shell sounds.

SystemPMI also allows flexibility forfuture needs. With no baseplates groutedto the floor, moving, relocating andupgrading pumps and/or motors can beachieved without any civil works.

The Haindl Group has paper mills in Germany, the Netherlands andAustria. All mills are certified according to the international standards

ISO 14001 and 9001. The group employs 2,300 people andproduces a total of 2.3 million tonnes of printing paper annually.

The new, unique installation concept SystemPMI,Pump Mill Integration, both saves time and gives

improved operating conditions, resulting in longer

lifetime for the pump, seal and coupling.

About 1.4 billion of the Earths popu-lation live without clean drinkingwater. More than 2.3 billion people stillhave no access to satisfactory wastewatertreatment. Water that is returned to the

natural environment is often heavilypolluted and carries viruses and life-threatening bacteria.

It is estimatedthat 80 percent of alldisease and morethan a third of alldeaths in the dev-eloping countries arecaused by the con-sumption of pollut-ed water. Additionaldepressing statistics

say that about halfof the Earths riversand lakes are todayseriously polluted.

WATER IS

NECESSARY FOR

DEVELOPMENT

All social and eco-nomic activity isstrongly dependenton a supply of freshwater and the

quality of thiswater. With a highrate of population growth and increasedeconomic productivity, many countrieswith scarce water resources soon reach aceiling for further economic developmentand a secure social welfare system.

Fresh drinking water and wastewatertreatment are two basic prerequisites forhealth and dignity. Every third person indeveloping countries still lacks these barenecessities for their social and economicwelfare. A secure water supply and environ-

mentally friendly wastewater treatment areof vital importance in order to protect theenvironment and to improve peoples stateof health, as well as relieve poverty.

HUGE EFF ORTS REQUIRED

The serious shortage of fresh water and theever worsening pollution of fresh waterresources in many regions make themanagement of the worlds combined water

resources an extremely demanding task.Huge efforts are required at several levels

in order to main-tain even andhigh qualitythroughout thecycle from watersources to thereturn of treat-ed wastewaterto the naturalenvironment.

GLOBALSOLUTIONS

The countriesof the world areco-operatingin various waysto solve theseh u g eproblems, anda seri es ofcollective effortshave been madevia organisa-tions such asthe UN. From

a global perspective, the latest was the bigEarth Summit conference held in Rio in1992 and the Agenda 21.

ACTION PLAN

Agenda 21 is an undertaking and a planof action for the development of theEarths resources in advance of the 21stcentury. All of the more than 150countries that took part in the Summitstand behind this important strategydocument. It sets out how we are tosucceed in meeting todays needs, and atthe same time ensure development forfuture generations.

Agenda 21 is about creating a betterworld on the basis of environmental, socialand economic considerations, and itcovers everything from poverty anddestruction of the forests to health and the

management of water and wastewater.

GROWI NG NE EDS

The need for water and wastewatertreatment is driven by factors such as morestringent quality requirements and newlegislation. In light of Agenda 21, it is easyto understand that this market is constantlygrowing. Other incitements to growth areprivatisation of the water industry, andurbanisation with its requirement for newand improved infrastructure.

In established welfare societies, there is

also a call for a modernisation andenvironmental tailoring of older existingsystems in order to achieve better waterquality. In general, wastewater treatmentplants are never phased out; they areextended and upgraded to meet greaterdemands as the population grows.

Even in Europe, approximately 30percent of the population has yet to beconnected to any municipal or statewastewater treatment plant.

The main obstacles to rapid growth arelack of capital, often caused by politicalsituations, municipal and centralgovernment budgetary restrictions, or

Clean Water

Water is a prerequisite to all life on Earth. It is the most valuable resource we have and, at the

same time, the one we most often take for granted. However, there are still more than 1 billionpeople who, today, live without clean drinking water!

It is also important to take care of the water we have used, so that it can later be reused. Here

the statistics are even worse more than 2 billion of the Earths population have yet to be provided

with access to wastewater treatment!

requisite for securing the lives of future generations, but

The industrial countriesproblems mainly concernwastewater treatment,

while areas such as Africaand Asia have a severeshortage of fresh water. Inthe long term, we willprobably see an evengreater need for efficientwater and wastewatersolutions in line with theeconomic growth of thedeveloping countries.

HEAVY

RESPONSIBILITY

Pumps are necessary to handle bothdrinking water and wastewater. The

From Raw Wat er to Drinking Wat erIn order to provide people with access to drinking water, functioningdistribution networks are needed in which raw water can betransported from water sources to treatment plants. In all cases wheregravitation does not provide the motive force, pumps are required.

There are often a number of pump stations that accumulate rawwater and surface water, which is then transferred to a central

treatment plant. In some cases, water is transported tens ofkilometers from water sources to areas with a shortage of water orwhich are heavily populated.

In order to be serviceable as drinking water, the water mustpass through treatment plants for a purification process. The wateris then pumped to households.

Wastewater M anagementIt is then important to manage water that has been used, andwastewater management is about collecting and treating thewaste from toilets, sinks, bathtubs and drains.

Used water is accumulated and transported to treatment worksto undergo a clean-up process before being returned to thenatural environment.

M echanical TreatmentWastewater is treated in a number of different stages. First, a

mechanical treatment is carried out using screens that separate outrags, paper, pieces of wood and other trash.

Sand and other heavier particles are separated by using a mostlyaerated sand trap. Iron or aluminum salt can be added to precipitatephosphate in order to meet environmental restrictions of this fertilizer.Sometimes, a special flocculation tank is built where the need ofmixers for good mixing and homogenisation is imperative. In thefinal stage of this mechanical treatment, wastewater passes slowlythrough primary sedimentation tanks, where the major part of un-soluted dirty sludge settles to the bottom.

M icro-organisms Pr ovide Biological TreatmentThe following stage, the biological treatment, is more or less theheart of a modern treatment plant. This kind of treatment is affectedby the metabolic activities of micro-organisms (bacteria, protozoaetc.) which float freely in the form of flocs in the basin. In this case,dissolved organic components, such as glucose and ammonia arebiodegraded by reproducing micro-organisms and having productsof lower energy. This means that the micro-organisms remove the

worlds pumpmanufacturers,therefore, assume aheavy responsibilityfor protecting theenvironment andhelping to providecleaner water, saysDan Drejenstam,head of ABS Water

& Wastewaterdivision.

It is importantthat we take ourrole very seriouslywhereever in theworld we operate,in order to helpprovide a securewater supply andwastewater treatmentof high quality.

There are also addi tional areas in

which pumps have an important role toplay in improving peoples lives, such

as flood protection, irrigation and, notleast, treatment of industrial wastewater,Dan Drejenstam adds.

LIFE FOR FUTURE GENERATIONS

By focusing on cost-effective pumping,ABS wants to help make water and waste-water treatment as efficient as possible.

The guiding principle in all ourresearch and development is to produce

highly efficient products that require aminimum of energy consumption andthat are easy to install, manage andmaintain, i.e. that in the long run providethe most cost-effective solution and thelowest Life Cycle Cost from all points ofview.

There is a long way to go yet beforeclean, fresh drinking water is a matter ofcourse in all the countries of the world.With collective efforts, the vision ofAgenda 21 can be realised: to live on theworlds resources, without, at the same

time, depleting them to secure the livesof future generations.

In a special treatment in which no dissolved oxygen is needed,special micro-organisms remove nitrate another fertilizer by

biodegradation.For these processes, mixers and aerators are used to circulate

and aerate the liquids, not least to prevent adverse side-effectssuch as odors and sedimentation. Sedimentation prevents thetreatment process from proceeding satisfactorily, as sludge thatgathers in corners or on the bottom of the tanks before it hasbeen sufficiently circulated, still contains some harmfulsubstances.

After the micro-organisms have done their job, the water is soclean that it can be returned to the natural environment with theaid of pumps and re-enter the Eco-cycle.

in the river Moldau, which flows throughthe city.The Prague SWTP belongs toPWK, Prague Water and SewerageServices Org-anisation, 66% of which isowned by Viv-endi Water.

THE DIGESTERS

The treatment plant contains twelvedigesters, six of them belong to the first stageand the other six belong to the secondtreatment stage.

The digesters of the first stage arecircle shaped with conical bottoms andmade of reinforced concrete. The diameterof each digester is 20 m, and the height is24 m, says Miroslav Podskalsky at theABS distributor, ATER s.r.o., a companywhich has been representing ABS in theCzech Republic since the early 90s.

Pragues main Sewage Water Treatment Plant (SWTP) purchased a number of

SCABAagitators for their digesters last year.

The agitators are now installed and have proven to be a very cost-effective solution

compared with other ways of mixing, according to the Technical Director of Prague

SWTP, Mr Cerych:

The savings are in the range of 30,000 EURO annually per digester!

The total theoretical volume of thesix digesters of the first stage is 30,936 m3,and the working volume is 26,298 m3.Dosing into the digesters is done 3 times

a day, with a maximum of 2,500 m3/day.

MORE EFFICIENT MIXING

Before the new agit atorinstallation, the mixing in thedigesters was made by acombination of biogas andhydraulic mixing says Mr Cerych,the Technical D irector of PragueSWTP. The rated power of amotor for the biogas mixing was33 kW, and for the hydraulicmixing 44 kW.

The agitators from ABS aredesigned to mix the whole tankwithout additional mixing. Therated power of the agitators are aslittle as 5.5 kW, which saves a lotof energy and costs: On a yearlybasis, we save 60,000 DM or30,000 EURO per digester!says Mr Cerych.

TAILOR-MADE

FOR OPTIMUM RESULT

The dry-installed ABS SCABA agitators

are designed for stirring applications inwater and wastewater,process, pulp and paperindustries; wherever aliquid is to be mixedwith another liquid, orwith particles or gas.SCABA agitators are ofa modular design whichcan be combined withvarious types of driveunits, seals andimpellers.

The fact that everyagitator is tailor-made according to processrequirements gives optimum features andprocess results in the specific application.

During the 13thand 14thcenturies, Prague was one of Europeslargest and most important cities. Today, Prague is a top tourist

spot, attracting millions of people every year. The city is famousfor its well-preserved buildings, with a city centre like a museum

of 900 years of architecture representing Romanesque, Gothic,Renaissance, Baroque and Art Noveau design.

M UCH LOWER ENE RGY COSTS

The top entry agitators installed in Pragueare of type DR85 with two propellers each,one large, 2.9 m in diameter, at the bottom

to create the main flow, and one smaller,

ensure a safe process, the agitators are alsoequipped withexplosion-proofmotors.

The agitatorswere chosen mainlythanks to their lowenergy consump-tion. They havealso proven to betruly reliable, givinga very smooth processat the same time as

they are effective,,Mr Cerych explains. In the long run, thesavings of 60,000 DM per digester is asubstantially low life cycle cost.

In a state prone to earthquakes, buildingprojects must make certain design adjust-ments to ensure measures are in placeto protect people and property during acatastrophic earthquake. Such designmethods were undertaken during the retrofit atthe Bradbury Dam located on Lake Cachuma nearSanta Barbara, California.

The problem:All of the soil at the base of the dam needed to beremoved due to a condition called alluvium whichallows soil to liquefy under the extreme forces thatcan occur during earthquakes.

To accomplish this, the groundwater table hadto be lowered so that excavation could take placeat the base of the dam.

Since 5,000 residents in the city of Solvangreceive their water supply from this dam, measur-

es were taken during this three-month project toassure that their service would not be interrupted.

The solution:ABS was contacted to design a system that wouldallow peak and off-peak usage, and continuousoperation of the water supply during the retrofit.

The system consisted of two 95 hp (70 kW)submersible JUMBO604 HV pumps, completewith electrical panels and 1,000 ft (300 m) ofpower and control cables. The pump systemproduced a flow rate of 3,500 USgpm (220 l/s)with 100% standby capacity.

The pumps were floated out on the lake on abarge, and installed at a depth of 65 ft (20 m)below the waters surface. Piping was installed on

the top of the barge and connected to a 21,000gallon (8,000 l) steel storage tank which servedas a surge and overflow tank for the project.

The result:The project was completed on time and operatedas designed, with uninterrupted water supply forthe city of Solvang during the whole constructionperiod.

Chevron Global Technology is a maj or company

in the oil industry in Venezuela, located close to

the M aracaibo L ake northwest of Caracas, as

are most of the oil fi elds and the oil companies

and refi neri es in the country.

Chevron recently placed an order for top entry

SCABA agitators of type 40 DH P -a for its

large oil refinery. The agitators, which will

operate under very severe and sensiti ve

conditions, are equipped with explosion-proof

motors. The agitators wil l be used to avoid

sedimentation and keep homogeneous a very

dense mixture of crude oil , solvents, naphtha

and kerosene in a round

shaped tank inside the refinery.

Large cooling water pumps will beinstalled in the Leningrad Nuclear

Power Plant, LNPP, in Sosnovy Boroutside St. Petersburg, Russia. Four of

the existing eight cooling water pumps

in the plant will be exchanged for newABS pumps with flood-proof motors.

One reason for installing the new pumps

is a risk analysis that predicts earth-quakes in the area; the flood-proof

motors ensure that the pumps are notdamaged if the area would flood.

The Galapagos Islands are a fascinating corner of the world, where only a few inhabitantsshare the territory with turtles, iguanas and hundreds of bird species. The place becamefamous and well-known world-wide when Charles Darwin carried out research there, and the

unique paradise islands are now visited by thousands of tourists every year.

The Galapagos belongs to Ecuador and consist of more than a dozen islands. Today, the

area is a National Park and Marine Biology Reserve, where environmental protection is a

natural lifestyle.

One of the largest islands is Santa Cruz, where several

resorts are located. A Santa Cruz hotel recently purchasedtwo AFP 1546 pumps for their sewage pumping station.

The pumps had an unusual way of finding their final

destination.

The pumps were first sent fromABS manufacturing unit

in Ireland to Cartagena in Colombia, and then on to

Guayaquil in Ecuador. The trickiest part was then delivering

themto Santa Cruz.

The Galapagos are located in the Pacific Ocean right on the

equator and more than 1,000 kilometres fromthe continent. The

solution was a Hercules C-130 carrier fromthe Ecuadorian Air Force, which was released by

the government to transport the pumps and accessories to the Galapagos.

But, if it was easy to load the plane with the pumps, using the cranes at the airport in

Guayaquil, imagine how difficult it was to unload and transport themto the pumping station in

a place without any facilities; no cranes, no trucks, no roads.

The only way was to hire natives who unloaded the pumps with their own bare hands and

then transported themon their shoulders for about 6 kilometres.The AFP pumps had a long and unusual journey, but are now in place and installed to serve all

the tourists visiting this Pacific Ocean paradise.

California Dam Project

An unusual voyage...

ABS has received an order from Holmen Paper at the

Hallsta Paper Mill in Sweden. The project concerns a newpaper machine for newsprint and journal paper, which willbe set up by Metso Finland during 2001 in the recordproject time of 70 days.

In the first phase, ABS will deliver more than 60 process pumps of types NB and BA. The pumps

will be incorporated into the new, unique ABS installation concept SystemPMI. The flexibility ofSystemPMI allows shortened project lead times and it also provides improved operatingconditions from several points of view. Read more about SystemPMI on page 4.
