Waste Water Treatment GCSE Chemistry

Flowchart nodes

• screening and grit removal to remove large particles

• sedimentation allows tiny particles to settle out from still water, which produces sewage sludge and effluent (the liquid which remains on top)

• the sewage sludge is digested anaerobically by specific bacteria

• the effluent is treated with aerobic bacteria to reduce the volume of solid waste
