- Your typical two chamber septic tank is the first step in pre-treating household wastewater by separating the solid waste from all the water leaving the home.
- The septic tank collects organics and inorganic, some of which sink to the bottom forming a biomass layer while some float to the top creating a scum layer.
- The first chamber in the septic tank has a fixed volume. Excess effluent transfers to the second chamber (grey water chamber).
- Partially clarified effluent is transferred from the second chamber to the septic field.
