IPS Sedimentation Unit

The IPS sedimentation unit is a compact plate separator designed for efficient removal of both settling and floating particles using the cross-flow principle. Wastewater enters through a distribution pipe for initial distribution, followed by complete flow distribution through a set of baffles.

Flow distribution is achieved by changing flow directions rather than using restrictions, which prevents floc breakage. Water then flows horizontally through parallel plates mounted at a 60-degree angle. The small distance between plates creates perfect laminar flow for efficient separation — settling solids slide down while floating particles move upward.

Settling particles collect in the sludge cone under the plate pack. For high concentrations, the IPS can be designed with part of the plate pack as a sludge thickener for storage and partial dewatering. Desludging creates a downward motion that releases particles stuck to the plates — this self-cleaning effect means the plate pack typically does not clog.

Clean water exits via underflow and overflow partitions. Floating particles can be removed by raising the water level using a skimming pipe system.
