Memclean® clarifiers are designed to flocculate and settle insoluble contaminants present in a wastewater stream. They are designed with a lamella style settler with a wide plate spacing to allow the system to handle high solids removal. They can be provided as a stand-alone item or used in conjunction with other wastewater products such as a chemical reaction tank system, filter press, transfer pumps, etc.

For smaller unit, a Memclean clarifier consists of a rapid mix compartment, polymer flocculation section and the lamella style clarifier. The rapid mix tank is provided with a mixer to rapidly blend the polymer with the wastewater stream. The flocculation section includes an electrically driven, variable speed, slow speed mixer to enhance the proper growth of the flocculation particles. The lamella style clarifier includes an air operated diaphragm pump to periodically remove the settled solids from the bottom of the clarifier. For larger, the rapid mix and flocculation tanks are on a separate optional skid.

Polymer from an optional chemical make-up tank is added to the wastewater in the rapid mix chamber. From the rapid mix chamber, the wastewater gravity flows to the slow mix chamber where polymer flocculation occurs. Following polymer addition and flocculation, the wastewater will flow by gravity through the inclined plate settler for the separation of the insoluble contaminants from the clear supernatant. 

The supernatant from the clarifier will gravity flow out of the unit. The settled solids will be periodically removed from the bottom of the clarifier via an air operated diaphragm pump. The Memclean clarifier is manufactured from carbon steel with polypropylene constructed separator packs. 

At rated flow rates, medium solids units can handle up to 750 mg/L of total suspended solids and High Solids units can handle up to 1,500 mg/L of total suspended solids. Higher solids loading can be accommodated by lowering the flow rate.
