The little sewage treatment plant
The sludge water is pumped from the washing plant into the sedimentation tank to settle in the funnel. Rising water runs via a cascade into the return to the wash or into a canal. No chemicals are used.
The sedimentation tank consists of a vertical pipe with a steep funnel in which the sludge collects. Water circulation volume up to 3m³. The tank has a manual and a pneumatic gate valve.
