Legacy - Model LMC-001 -Circular Mechanical Clarifier
In the wastewater treatment industry, there are three (3) types of clarifiers used for clarification of secondary effluent: rectangular, mechanical, and gravity hopper. Legacy Environmental Process manufactures all three (3) types of clarifiers for various applications, although the most commonly used on package wastewater treatment systems is the gravity hopper type.
The mixed liquor from the aeration chamber contains millions of micro-organisms and organic solids that exert an oxygen demand on the receiving stream. The purpose of the clarifier is to physically remove these solids that will settle on the bottom or float on the surface within the chamber. Settled solids in the clarifier are removed by means of a sludge return pump which discharges them back to the aeration chamber for further treatment. Floating solids are also removed from the clarifier via a scum skimmer and returned to the aeration chamber for additional treatment. The removal of both types of solids produces a clear liquid called supernatant. The supernatant then passes through a baffle to an effluent weir of the clarifier for eventual discharge to the receiving stream.
