Brief Description about the UASB System

The up flow Anaerobic Sludge Blanket (UASB) process is an Anaerobic Treatment Systemwherein the organic matter is digested, absorbed and metabolized into bacterial cell massand biogas. The domestic wastewater treated in a UASB reactor is suitable for discharge inriver water or for irrigation after polishing in high rate pond. The Biogas generated can beutilized for generating electricity. Sludge cakes after dewatering and drying on sludgedrying beds will be suitable to be used in fields as manure. The UASB system also does notrequire any external energy and mechanical equipment. It also has a modular constructionand occupies less space. The maintenance requirements are less as compared to theconventional systems.

The UASB process is a combination of physical and biological processes. The main featureof physical process is separation of solids and gases from the 1iquid and that of biologicalprocess is degradation of decomposable organic matter under anaerobic conditions.

In the UASB treatment concept, the treatment tank consists of an up flow reactor with afeed inlet distribution system at the bottom of the reactor and a three-phase gas-liquid-solids separator (GLSS) at the top. The waste water is evenly distributed over the reactorbottom through feed inlet pipes and flows upward through a bed of anaerobic sludge inthe lower part of the record called the digestion compartment. During passage through thesludge bed particular matter is entrapped and the degradable matter is completely orpartially digested. Dissolved organic matter is removed from the solution by the anaerobicbacteria and converted into biogas and a small fraction into new bacterial biomass. Thebiogas phase Gas-Liquid-Solid Separator (GLSS) is installed. The biogas product iscollected in a gas collector gas (Gas Hood) from where it is withdrawn. The remainingwater-sludge mixture enters a setting compartment where the sludge can settle and flowback into the digestion compartment. After setting the water is collected effluent guttersand discharged out of the reactor to the final polishing unit (FPU) to meet dischargestandards.

The preventive and corrective of maintenance also becomes very important for suchinstallations and are requires to be given desired priority.

VI. Proceeding of the meeting held on 06.10.1993 regarding safety measures and safeequipment for operation and maintenance staff employed on sewerage systems isreproduced as under. Relevant sections of the same may be referred for the contract, as perthe directions of the Engineer-In-Charge.

A meeting was held under the Chairmanship of Sh. Gurdip Singh, Engineer-in-Chief,Haryana, PWD, Public Health Branch, Chandigarh on 06.10.1993 in respect of issuesinvolved in the safety measures and safe equipment requirements for operation andmaintenance staff employed on sewerage systems. The list of participants is annexedherewith.

Though there were many issue related to this aspect, since the main theme was the safetymeasures to be adopted by the workman for safe operation maintenance of the seweragesystem particularly cleaning of the choked sewers, it was suggested that therecommendations may presently be concerning the main theme i.e. the safety measures tobe adopted by the workman.

After detailed deliberations the recommendation are grouped as under: -ii) Hazards involved.iii) Precautions to be adopted by the workman.iv) Safety equipment to be provided to such workman and guidelines for safeoperation maintenance.v) Preventive and corrective maintenance of the sewerage system.

The sub head wise details of each item are covered as under: -

i) Hazards involved

“Sewer gas” is a mixture of gases in sewers and manholes containing abnormally highpercentage of carbon dioxide, varying amounts of methane, hydrogen, hydrogen sulphideand low percentage of oxygen caused by septic action through the accumulation of organicmatter inside the sewer. The actual hazard is due to the presence of high levels of methaneform an explosive mixture or the oxygen deficiency or hydrogen sulphide in excess ofpermissible levels. Sometimes trade wastes may also contribute to other gases like chlorine,ammonia, sulphur dioxide etc.


- 90 -

ii) Precautions to be adopted by the workman precautions against Gas Hazards.When a sewer or a manhole has to be entered of cleaning clearing an obstruction, it will beadvisable to in for efficient ventilation either natural or forced and get assured that theatmosphere inside the manhole of sewer is from oxygen deficiency and noxious gases orvapors. Where such clearance of the noxious atmosphere by ventilation is not possible ortimeconsuming, the following precautions must take before entering into the manhole or sewer:-a) Traffic warning signs should be erected.b) No smoking or open flames should be allowed and sparks guarded against.c) Only safety, explosion-proof electric lighting equipment or mirrors for reflection of lightshould be used.d) The atmosphere should be tested for noxious gases and oxygen deficiency.e) If the atmosphere is normal, the worker may enter in the manhole or sewer with safetyharness attached with two men available at the top.f) If any noxious gas or oxygen deficiency is found, forced ventilation should resort tousing a portable blower.g) Frequent tests as in item (IV) should be confirm even if the initial tests ate satisfactory, asconditions may change during the period workers are inside the manhole or sewers.h) If forced ventilation is not possible or satisfactory and men have to enter urgently such asin saving a life, a gas mark should worn and extreme care take to avoid all of

ignition if inflammable gas is permissible safety lights (not ordinary fly lights),rubbers or non-sparking shoes and non-sparking tools should be used.i) Only personnel experienced in the line and familiar with the dangers involvedin working in a noxious gas environment and fully equipped with the properprotective safety equipment should be allowed to enter.

ii) Precautions against infections

The personnel working in sewerage maintenance systems are prone to infections and hencethe following precautions should be taken: -

a) Emergency first aid treatment kits shall be provided to take care of all minorinjuries like cuts and burns.b) The workers should be educated about the hazards of waterborne diseases suchas typhoid and cholera through sewage and tetanus through cuts and wounds.c) The importance of personal hygiene should be emphasized and the workersshould be instructed to keep finger nails short and well trimmed, not to brushfingers when they are sore, wash hands with soap and hot water before takingfood and to keep fingers out of nose, mouth and eyes, because the hands carrymost infections.

d) Use of rubber gloves and gum boots should be insisted so that sewage orsludge does not come in direct contract with the hands and feet.

e) In laboratory work, only pipettes with rubber teats should be used to preventcontamination of the mouth. Laboratory glassware should not be used for drinking


- 91 -purposes. In no event food should be prepared in the laboratory.

iv) Safety equipment to be provided to such workman and guidelines for safeoperation maintenance

a) Safety Equipment

The various safety equipments that are normally required in sewer maintenance work arebreathing apparatus, portable lighting equipment, non sparking tools, portable airblowers, safety belts and inhalators. The use of particular safety equipment governed by thedetection of various gases and oxygen deficiency.

Knowledge of the type of gases in the atmosphere of the working locationbecomes essential for the selection of the right type of safety equipment. Equipment andsimple tests for detection of various gases and oxygen deficiency are furnished inAppendix-I.

Normally following safety equipment should be available in each Sub Division.Their number will depend upon the size of the town.

a) Safety belt.b) Safety helmet.c) Emergency (First Aid Kit)d) Air blower.e) Gas mask respirator.f) Air line respirator.g) Pure oxygen respirator.h) Air respirator.i) Portable lighting equipments hand lampsj) Two mirrors and torch

v) Procedure for working in a SewerTo ensure proper safety standards the following steps should be followed: -

Step – I Before leaving the stores.a) Collect and check all safety equipment.b) Check working location with supervisor and list all known or potential hazards.

Step – II On arrival at site.Set up at site.

a) Ventilate the system (guarding all openings) on a sewer open up. The working manhole. Next manhole up stream. Next manhole downstream.

This is the minimum requirement. It should preferably be two manholes on upstreamand downstream. Use to be made of blowers if necessary.


- 92 -Step – III Entry Procedure

Natural ventilation as described in step Ii (b) above should preferably to for 2 hoursbefore any entry.a) Check for gas (if in doubt stay out).b) Tie safety belt and rope before entering.c) Check ladders, step iron etc. for defect (if in doubt use a rope attached to the safetybelt).d) Keep safety ropes, spare lamp, breathing sets close to working area for immediateuse in ca of emergency.e) With the help of mirrors and torch, the status sewer to be cleared may be checked.In deep sewers the water level in the sewers should be checked before entering.Portable sets should be available while working in deep sewers.

Step – IV Working inside the sewerEvery three minutes the top man calls to the man working in the sewer. Everymessage shall be acknowledged.

Step – V Completion of work

a) Top man informed and ready.b) Danger (Normally last man out) checked that all tools, ropes etc. are out and

that the sewer is clearc) Replace all grids, guard rails, manholes covers.

d) Road signs to be removed and site cleared.e) Supervisor to be informed that work is completed.f) Wash thoroughly before eating or

vi) Guidelines for giving first aid to a gas victimb) Remove him to fresh air as soon as possible.

c) Apply artificial respiration with resuscitator if he is not breathing and if available,otherwise mouth to mouth resuscitation be administered.

d) If the victim does not respond within two minutes, remove him to the nearest hospital.

vii) Preventive and Corrective maintenance of the sewerage system

a) Preventive MaintenanceMany of the causes leading to the clogging of sewers can be prevented by periodic cleaningand removal of silt accumulations in sewer lines including manholes while the system isfunctioning.Each of the sewer maintenance gangs shall be under the supervision of a competent personwell trained in the use of sewer cleaning and safety equipments and qualified to render firstaid service in case of emergencies.

The covers of all manholes immediately upstream and downstream of the particularmanholes into which men are to enter should be removed and kept open for at least half an


- 93 -hour for natural ventilation. Sufficient protective barricades shall be erected on the street toregular flow or prevent entry of the traffic in the area.

After the lapse of this period, there should be no noxious gas or vapour or oxygendeficiency as evidenced by the tests described in the relevant manual additional time maybe allowed if the foul atmosphere has not cleared up. Forced ventilation shall be resortedfor purging out the foul atmosphere inside using portable blowers. If the forced ventilationis already provided for in the sewerage system, the evacuation of air will be carried outfrom one end with the manhole covers kept open permitting the entry of outside air into thesewer system. It has to be ensured that the atmosphere inside the manhole is safe before theworkers are directed to enter the manholes.

With the cleaning of the sewer other repairs, if any, to the inside of the manhole, the footsteps the cover etc. should be carried out. In the case of larger conduits through which aman can walk for the work will also include the examination of the inner surface of theconduit and carrying out necessary repairs. If a sewer is damages, it has to be tackledseparately and not by routine maintenance personnel.Based on local needs, a schedule of cleaning of all the sewers in the system has to beprepared and followed. The frequency of cleaning depends on the nature of sewage flowingin a particular section and the velocities obtained in the sewers during the peak flow.

b) Corrective maintenanceCorrective maintenance becomes necessary for removal of obstructions in sewers caused byexcessive silt accumulation or damage leading to the break down of the system with flowsmuch lower than the normal.

The sewer gang for this type of work should consist of specially trained men who are awareof the hazards and capable of coping with situations calling for prompt action. Thesupervision in this case should be entrusted to a responsible person well versed in the useof the special sewer cleaning equipment, safety equipment and in first aid. For locating theexact position of blockages, it is necessary to commence observation from the overflowingmanholes down the line until the first manhole with little or no flow is reached. The sectionbetween this manhole and the one immediately upstream is the one which should becleaned first, after taking the necessary precautions for the safety of the workers. Theaccumulated sewage should be pumped out into the manhole further downstream and themouth of the sewer exposed after allowing for natural ventilation for one hour, by keepingall manholes within a radious of 200 m open, tests shall be conducted to ensure that theconditions are satisfactory for the workmen to enter the manhole, resorting to forcedventilation, if necessary. Air from the bottom of the manhole should be sucked out by anexhaust pump which will enable fresh air being drawn into the manhole. This is helpful toevacuate gases heavier than air such as Carbon Dioxide, Petrol vapour and Hydrogensulphide. Sometimes air may be blown inside the manhole which pushes out the foul gasesfrom the manhole. This is very effective for gases which are lighter than air, such as Carbonmonoxide, Methane, Nitrogen etc. if the sewage flow into the manhole is heavy andpumping has to be carried out continuously to enable men tot get in work. It is preferable toblock the mouth of the sewer on the upstream side and start pumping from the second next


- 94 -upstream manhole while the work of clearing the obstruction in the sewer down below isbeing carried out.

In this case of simple blockages, the flexible sewer rod of the bamboo and manila rope typewill be sufficient. A ferret with a fire hose can also be used for breaking and removing sandstoppages. Where a rodding machine with flexible sewer rods is available. It can be usedwith suitable tool attachments to break the blockage.

When the above methods are not successful or damage to the sewer is suspected, thelocation of the blockage can e found by the use of sectional rods from either end of theclocked sewer. Once this is located, the sewer length near the blocks can be exposed by theopen excavation to examine and set right the sewer line. If the damage to the sewer isextensive and is caused by poor foundation then the stretch between the two manholes mayhave to be relaid on a proper foundation.

In case it is not possible to wait for proper evacuation of the foul atmosphere inside amanhole or a tank and men have to enter urgently to save a life, then only men trained towork with safety belts, gas masks and other safety equipment may be allowed to enter themanhole, observing the precautions against gas hazards and under the guidance andsupervision of a competent supervisor. In an emergency the supervisor should promptlyget in touch with the nearest police station, a fire station and a hospital for help.

Where the material of the sewer, especially concrete is damage, the cause must beinvestigated and due rectification carried out. If flows much lower than the designed oneslead to low velocities and consequent septicity resulting in the production of hydrogensulphide, routine chlorination of the sewage may have to be considered.

Force Majeure

(76) Force Majeure shall be read as per standard conditions of CPWD specifications.In addition to this following shall in regards to force majeure; Except followingconditions no other condition will be considered as Force Majeure condition: -

a. Failure of electric supply from DHBVN.b. All electrical break down at H.T / L.T control gear, switch gear, equipments ofsubstation upto a reasonable time as assessed by the Engineer-in-Charge of the work.

9 Data Collection

General

Regular record and reports of the wastewater treatment plant operation can be used for many purposes.The collected data serve the plant management to judge on the performance of the plant and to justifydecisions concerning operation and maintenance, allocation of budget and expansion proposals for the up-gradation of the plants. These data shall be used as guide lines by the operating staff to regulate, adjust andmodify the plant facilities and treatment processes.

9.1 PurposeAn efficient communication between the personnel involved in the operation of the plant is of crucialimportance to achieve and maintain a properly functioning STP with satisfactory treatment results. Thecommunication, though in some cases may be verbal, should be essentially written and documented. Onlywritten reports allow an adequate flow of information amongst plant operation and management staff tokeep tract of the reasons for possible malfunctioning of the STP as well as to look into its performance.The various information streams are compiled into reports and result into an evaluation report which isprepared by the Assistant Plant Manager and submitted to the Plant Manager (Fig. 9.1)

1.1 DAILY MAINTENANCE

Daily maintenance of the biological, processes in the UASB reactor follows logically from the precedingparagraphs. Data should be obtained on the functioning of the plant, and checked. If the waste water flowthe biogas production, and the effluent concentrations are normal no actions should be taken.

Regular maintenance of the UASB reactor hardware should consists of checking of the screening system,the effluent gutter and the gas collectors.

The feeder system of the UASB reactors can become choked over time. Therefore, it is important to keepdata on pimp pressure, for it can Indicative for the amount of food inlet points choked. To maximize theperiods between two sequential required cleaning operations, vigorous screening In four stages must becarried out, continuously requiring day and night operations by sweepers of the screens.

It is required to empty reactor once after the first one year of full operation to check the complete feederand sludge withdrawal systems, especially the valves and the internal pipes for any accumulation of debris,sludge, etc. The routine maintenance requirement of feeder and sludge withdrawal, systems must beestablished on the basis of such as inspection.

The effluent gutters are essential for the removal of the effluent of the reactors. If the gutters are not leveledand the water in the V-notches is not at the same level in all of the notches in one gutter, or in differentgutters, then the flow will not be even. This will lead to more solids washout than necessary. Similarly,blocking of the V-notches of the effluent gutters will lead to an uneven flow over the effluent gutters willlead to an uneven Flow over the effluent gutters. Therefore the effluent gutters has be inspected on aregular basis to remove any material blocking an even out flow over the v-notches in the glitters. The level


- 123 -of gutter's has to be inspected on a regular basis and if uneven flow is seen. adjustment of the level of thegutters should be made.

Regular maintenance of the effluent gutter consists of the following activities. Cleaning if done from thetop of the reactor.

1. The sleeper cleans the v-notches of the gutter with broom, once in every shift (3 times/day)2. The sweeper removes sludge from the effluent gutter with a brush or with jet once a day.

A floating layer on top of the surface of the reactors should be removed when required.

1. The sweeper breaks the floating layer with a rake.2. The sweeper removes the material at one- side of the reactor with a rake.3. The material is put in a wheelbarrow and disposed at the dumping site.

The gas collectors should be checked for leakage. Leakage is easily seen, by bubbles in the water and byapplying a soap solution showing bubbles at leaks in piping. This can be done a regular basis. If the gascollectors are leaking, the valve at the end of one bay in the gas link should be first closed and then theyshould be repaired as soon as possible. Regular maintenance includes: -

1. Open watch boxes and remove floating layer inside the gas collections.3. Check gas collectors and pipes for gas leaking and repair when necessary.

1.1.2 PREVENTIVE MAINTENANCE

Preventive maintenance should be carried out, on a regular basis. It was prevent the reactor formhaving to put them out of operation unnecessarily. Preventive maintenance aims at minimizingrepairs and maximizing lifetime of the components of the Plant. For this reason, maintenanceactivities are carried out according to a fixed schedule.

1.2.1 Distribution system

1. Check screening stages.

2. A first check of the complete system including valves and holes should be made afterone year, or earlier when required. Routine check can be established on the basis of the firstinspection observation.

1.2.2 UASB Reactor


- 125 -The UASB reactors themselves require little attention. Every five year the followingmaintenance should be carried out.

1. Alternately each reactor should be put out of operation.

2. Discharge sludge-to-sludge drying beds.

3. Provide ventilation by removing part of the hatch boxes.

4. Remove all grit form the bottom of the reactor through the drainage pit provided.

5. Clean the inside concrete surface.

6. Apply new coating on the concrete surface.

7. Check quality of feed inlet pipes and replace when necessary.

8. Check fixing of the feed inlet pipes, both at the distribution boxes and at the bottom.Change corroded fixing material when necessary.

9. Check position of PVC sheets.

10. Check the fixing material of the PVC sheets and replace when necessary.

11. Check the quality of gas collectors and carry out repair whenever necessary.

Executive Engineer


- 126 -1.2.3 Effluent gutters

1. The effluent gutters have to be checked for leveling and alignment once a year. Eachgutter should be horizontally leveled and all gutters in one reactor should be at the same level.

2. Possible settlements should be removed.

1.2.4 Sludge withdrawal system

1. The spindles of the valves have to be greased every three months.

2. The glands and packing of the valves have to be checked every three months, andreplaced if necessary.

3. The cement works have to be checked yearly and repaired when necessary.

4. The sludge filtrate water pumps should be maintained.

5. Electrical wiring has to be checked every year.

6. Corrosion on electrical connections has to be removed every year.

A summary of the maintenance activities is presented in the following pages. Most activities areeither three-monthly or yearly; the three-monthly activities are to be carried out in the months ofJanuary, April, July and October.

The yearly activities are to be carried out in the month of October after the monsoon.

1.5 SHUT-DOWN AND STANDSTILL

At shut down of the plant, the sludge will settle to the bottom of the reactor. The biologicalactivity of the sludge decrease only slowly during stand care should be taken that the sludge isnot exposed to aerobic conditions. This might occur for instance, when the reactor if flushedwith clean water for prolonged period of time.

At shut down of the plant the gas production wil1 decrease. At a prolonged period of plantstandstill, the pressure in the gas collections system can drop and air may enter into system. Inthis situation internal parts of the gas flare, the gas meter and the pressure/vacuum releasevalves that normally are not in contact with the atmospheric air start to corrode. These partshave to be protected, for instance by greasing.

Executive Engineer


- 127 -

If the water level in the tank is lowered during shut-down It should be taken into account thecapacity of the vacuum release valves is limited and that imploding of the gas collectors mayoccur at fast withdrawal of the reactor contents. At lowering of the water level in the reactor it isadvised to open the manholes on the top of the gas collectors. Only after re-establishing themaximum water level the manholes can be closed and sealed.

When manholes are opened and in general with every type of work on the gas collectors itshould be taken into account that an explosive mixture of air and methane can develop in oraround the gas collectors. When it is necessary to enter the reactor, while sludge is present, ithas to be realized the methane is being formed continuously. A proper ventilation of the reactoris absolutely necessary. Very Strict rules concerning upon fire, spark emission etc. Should beused when entering the reactor plant person should wear respiration equipment. Measurement ofexplosion risk and hydrogen sulfide con cent ration have to taken frequently when repair worksare carried out.
