Typical Municipal Flow Diagram

The numbers in the table below correspond with the numbers on the diagram.

1. RAW SEWERAGE – Lift stations, CSO facilities, headworks, prisons, hospitals, restaurants.
2. SCREENINGS / SEPTAGE – Raw concentrated solids including rags, plastics and hair.
3. CLARIFIER SCUM PITS – Primary or Secondary scum without plugging or air binding.
4. SLUDGE TRANSFER – Eliminates “roping” and clogging in clarifier underflow to thickeners.
5. RAS / WAS – Continuously conditions Return and Waste Activated Sludges.
6. As above
7. THICKENED SLUDGE / DIGESTED SLUDGE TRANSFER – Handles high sludge consistencies.
8. As above
9. DIGESTER MIXING – Rotamix system conditions and mixes in a dual-zone rotational flow pattern.
10. DIGESTER RECIRCULATION – Elimiates heat exchanger clogging while conditioning sludge.
