ABSTRACT:
A liquid clarification system for separating solid and/or chemical contaminants from an unclarified liquid wherein a variable influent is passed through a settling clarifier to separate a portion of the contaminants from the liquid forming a semi-solid sludge. The sludge is passed into a reservoir and delivered to a filtration system at a controlled predetermined percentage of solids material. The solids material is circulated through the filtration system to form a filter cake on the septum of filters carried in a filtration chamber and the liquid is clarified by passing through the filter cake formed thereon. Periodically when the filter cake must be reformed, the expended cake is removed from the septum and conveyed from the filtration chamber through a sludge drying system to be discharged as dry solids waste material.
