Faeces is dried

1

The sewage sludge is carried
into a drying oven in which the
sludge is boiled dry of water.
The water vapour from the sludge is
separated from the drying oven via a pipe.

Sludge is burned

2

The sludge is carried into a burner,

where it is burned and heats a

boiler with water inside. The

vapour from the boiler is directed into a

steam engine and a generator that

generates power for the entire process.

Vapour is reused for power

3

The surplus vapour from the

steam engine is directed into the

drying oven, where the energy is

used for heating and drying the sludge.

Subsequently the vapour condenses into

water and is directed back to the boiler.

Helping the planet by

drinking purified poo

They used to say ‘where there’s muck there’s brass’, but there’s

water too. In the ‘omniprocessor’, a system of steel pipes converts

sewage sludge into pure drinking water, generating enough power

to cover its own operation and transfer more to the electricity grid.

SOLUTION

Water vapour is

filtered and condensed

4

The evaporated water

from the sludge is

directed through a

filter that purifies it further.

Subsequently the vapour is

directed through a heat

exchanger where it condenses

into water. The distilled water is

now 99.9% pure and can be used

for irrigation or as drinking

water after having been enriched

with minerals such as calcium.
