Abstract

A liquid clarifier in the form of an enclosure in which a conical filter membrane is mounted. An inlet is mounted to the enclosure below the conical filter membrane and an outlet is mounted to the enclosure above the membrane so than an upflow of liquid is created during filtering. The upflow causes the liquid to sweep across the conical filter membrane to prevent accumulation of particulate matter on the membrane. A conical baffle is coupled to the inlet to reduce turbulence of the liquid at a lower end of the enclosure to promote separation by gravity of the particles from the liquid.
