WATER FACTS
Water covers 97% of the earths surface but only 0.6% fresh water is available to use
We use 150 l/day of water each
Water freezes from the top down leaving fish unharmed.
It takes 1 tonne of water to grow a kg of wheat
It takes 20tonnes of water to produce 1 kg of coffee
By 2025 50% of the worlds population will suffer from water shortage
You contain 55-70% water
A child dies every 15 seconds due to water borne diseases
We flush toilets with drinking water
We wash cars and equipment with drinking water
HUBER SE . www.huber.de
Water is unique and life is not possible without it
Do you take it for granted
CLEAN WATER
HUBER SE . www.huber.de
Problems that occur with water
People have to drink polluted water-Illnesses
Pollution from Industry-illnesses, poisoning, no fish
HUBER SE . www.huber.de
Wars – If rivers are diverted, Dams are built, High abstraction rates upstream, Boundaries change.
When President Anwar Sadat signed the peace treaty with Israel in 1979, he said Egypt will never go to war again, except to protect its water resources. King Hussein of Jordan has said he will never go to war with Israel again except over water and a previous United Nation Secretary General Boutros Boutros-Ghali has warned bluntly that he next war in the area will be over water
Drought -Crop failure, Animals die, starvation
WATER PROBLEMS
HUBER SE . www.huber.de
PROBLEMS THAT OCCUR WITHOUT WATER
. Ecological and social re-engineering. When Rivers are diverted to grow crops upstream Lakes Dry up
The Aral sea is only a ¼ of its size because the Russians divert the river flow to irrigate crops upstream, To grow cotton in a desert.
75% of the population have left. The rest have very little unsalted water

INDUSTRIAL APPLICATIONS
• WATER COSTS ~£1/ m3 OR TON FROM THE MAINS.
• IT COSTS ANYTHING FROM £.80 TO £20/ M3 TO DISCHARGE TO DRAIN
• ANY REDUCTION IN WATER USE IS A SAVING• ANY REDUCTION IN POLUTANTS IS A
REDUCTION IN COSTS.• YOU MAY HAVE A PERMIT THAT RESTRICTS
YOUR DISCHARGE. FINES &LOSS OF GREEN CREDENTIALS??
• YOU PAY FOR SLUDGE DISPOSAL INCLUDING WATER
• YOU PAY ~£100 TONNE TO DISPOSE OF MATERIAL TO LANDFILL
HUBER SE . www.huber.de
Effluent plant
Why pay for discharge of solids and BOD (biological Oxygen Demand)
• A screen can remove solids.• Removal of solids reduces BOD
• Micro screens can remove even more solids
• Dissolved Air Flotation can remove fine solids
HUBER SE . www.huber.de
Screens for solid removal
Reducing ongoing costs
•Cleaning when required reducing power
•Efficient slow rotation reducing power requirements and maintenance.
•Washing when required reducing water use
•Screenings washing to reduce odour note totally enclosed solids removal.
•Compaction by the auger reducing screenings volume
•Stainless construction prolonging life and reducing maintenance

SLUDGE TREATMENT
Sludge’s for treatment
Huber with chemistry and mechanics thicken the slurry and remove some water
By Thermally drying the sludge is reduced to a pellet and water evaporated away
WHY TRANSPORT WATER?
HUBER SE . www.huber.de
SLUDGE PELLETS
Why not reduce the water volume and create something useable
The sludge can be dried to a pellet which may be suitable for fertiliser or fuel for a CHP plant (combined Heat and Power)

WHY DISPOSE OF GULLY WASTE / ROADSWEEPINGSD TO LAND FILL
HUBER SE . www.huber.de
The Grit can be recycled
RECYCLING CLEAN GRIT AND RECYCLING CLEAN GRIT AND SAVING LANDFILLSAVING LANDFILL
From road sweepings and Gully waste we can get clean grit, bio-degradable material for composting and water for treatment. Reducing landfill by 90%

THE FUTURE
As populations increase water will be scarcer
Carbon footprint will become more important
Energy recovery will be necessary
Phosphates and Nitrates recovery will be significant
P from P?
Energy from Waste
Water recycling blue to grey to black to irrigation and fertiliser
Food waste collection to get methane first then fertiliser
Heat from waste
Plastics recycling with less impurities
Grit recovery from road sweepings
Conversion of wastes to resource to improve the bottom line and more importantly improve the environment
