The Ellis Inclined Plate Clarifier (IPC) membrane ultrafiltration water system offers a large settling surface area in a very small footprint. The Ellis Inclined Plate Clarifier uses only 10% of the settling area for the separation of solids than traditional settling clarifiers. To maximize the settling surface area, the IPC uses a series of closely spaced plates installed at a specific angle. The driving force for this separation is gravity acting upon the entrained solids. The compact volume with a low clearance and footprint requirements saves on installation costs and makes the Inclined Plate Clarifier easy to access and service.


Inclined Plate Clarifier

Chemically pretreated wastewater enters the stilling chamber removing kinetic energy. All solids begin a downward flow in the quiescent water. After flowing through the sludge chamber, the flow is forced upward through the plates. This is referred to as a counter current flow pattern.

As the flow rises between the plates, solids fall from suspension under the natural force of gravity. This minimizes energy requirements and allows for easy, clean separation. The heavy solids will settle onto plate and slide down the inclined surface to be collected in the sludge hopper. The IPC has minimal moving parts and wear components leading to direct operation and maintenance cost savings for the customer.

The effluent flows to the top of the plate area and decants over an adjustable weir. Solids can be intermittently discharged from the side of the sludge chamber using the optional auger system.
