The CL-304A is a modular clarifier that is capable of pre-treatment, sewer discharge, or recycling wash water. Utilizing cross-linked polyethylene cone-bottom tanks with a steep slope of up to 55 degrees, the unit delivers maximum solids separation. The CL-304A features a full open top with removable lid and a heavy duty metal stand with cradle, and also incorporates a separator top cone to effectively divide the tank into top and bottom chambers, making this an effective industrial water filtration system. Influent water enters the tank and through a series of processes, heavier solids settle to the bottom while free-floating oils rise to the top to be skimmed and drained to a nearby oil-decanter container. The treated water is then forced downward into a uniquely designed piping system where it is discharged from the clarifier. No other wash-water treatment system is as versatile and modular as the Water Maze CL. The unit can stand alone or, in some cases, be matched with a Filter Pac module to serve as a solids separator, a treat-and-discharge unit or even a recycle system.
