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

CLEAN WATER
Water is unique and life is not possible without it
Do you take it
for granted
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
WATER PROBLEMS
Drought -Crop failure, Animals die,
starvation
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

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

LIQUID WASTE
AT HUBER WE SPECIALISE IN LIQUID WASTE DISPOSAL
CONVERTING
RAIN WATER TO SHOWER WATER
SHOWER WATER TO LOO FLUSHING WATER
SEWAGE TO IRRIGATION WATER
SLUDGE TO CAKE
REDUCING MOGDEN CHARGES
CONVERTING SLUDGE TO PELLETS
CREATING FUEL FOR BIOMASS BURNERS
REDUCING TRANSPORT CHARGES FOR SLUDGES
PREPARING FOOD WASTE FOR ANAEROBIC DIGESTION
PLANTS
RECLAIMING GRIT

Huber are Filtration Engineers specialising in Liquid/Solid separation. We
make
Screens and screening compactors to remove solids
Grit traps and grit washers to remove sand and grit
Fine screens for polishing effluents
Sludge Thickeners
Dryers for slurries
Effluent Treatment plant
Membrane filters
Bio reactors
Clarification equipment
Sludge presses
Sludge driers
Special dirty water heat exchangers

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
WHY TRANSPORT WATER?
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
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)

RECYCLING CLEAN GRIT AND
SAVING LANDFILL
The Grit can be recycled
From road sweepings and Gully waste we can get clean
grit, bio-degradable material for composting and water
for treatment. Reducing landfill by 90%
HUBER SE . www.huber.de
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
