Flo Trend^® Systems' Clear Flo Clarifier is a portable inclined-plate clarifier with a flash-floc tank and motorized rake for discharging collected sludge. With a pre-flock tank, this unit is able to handle flow of up to 80 gpm with 500 ppm to 100 ppm solids. (Higher concentrations of solids can be processed with a corresponding higher flow rate of concentrated sludge removed from the collection tank of the clarifier.)
