At Thames Water Maple Lodge Sewage Treatment Site the main electricity generation method is combined heat and power (CHP).
The first stage of this process is called anaerobic digestion, which is when sewage sludge is brewed and chewed – brewed in warmed-up vats and chewed by bacteria, which breaks down biodegradable material, a by-product of which is biomethane, or biogas.
Methane from the sludge is burned to create heat, which in turn generates electricity.
Forward Industrial Utilities Products Ltd were asked to install a temporary pipeline for the re-routing of the Biogas.
