Sedimentation tank for drainage system
Dortmund type Sludge Sedimentation Units are mainly used for the final sedimentation of sludge produced by biological and chemical-physical processes. The physical treatment clarifies the effluent and thickens the sludge.
The plant has a hopper with a square/rectangular bottom, a cone-pyramid shape and walls which slope more than 50° to collect the settled sludge.
In this treatment process the sludge becomes continuously heavier and heavier due to the initial downward movement towards the bottom and reaches its maximum weight in the area under the baffle (bottom hopper).
In the “thickener” version for organic sludge, the tank is fitted with internal pipes and flanged stub pipes in AISI 304 stainless steel to extract the sludge from the bottom of the hopper.
Supplied as standard

- sleeves to connect the inlet and outlet pipes,
- sloping reinforced concrete slabs to create the cone-pyramid shaped sedimentation section,
- feeder pipes,
- PVC central cylinder baffles,
- peripheral overflow channel in AISI 304 stainless steel with relative Thompson profiles and scum baffle.
