Thames Water ramps up sewage recycling programme
Published on by Water Network Research, Official research team of The Water Network in Business
THAMES Water is enhancing its ‘poo power' programme already in operation at Bishop's Stortford in a bid to cut energy costs.
It is setting up six new thermal hydrolysis process (THP) plants at main sewage plants. They are effectively pressure-cookers that condition sludge, the leftover solids from waste water treatment, by heating it up to around 160 degrees Celsius.
The pre-conditioned sludge then goes into existing anaerobic digesters - large, airless vats which break it down, producing biomethane gas that is then burned to create heat and generate renewable electricity.
