The DMax™ filtration process: A specific amount of dry treatment chemical is automatically transported by a Flexicon conveyor from the chemical hopper (#1) to the working tank (#2) that contains colloidal rinse water from a manufacturing process. The dirty water and chemical mixture is then agitated for a preset time, then automatically discharged into the pressure filter (#3) that removes the solids and discharges liquids into the clean tank (#4). An equal volume of clean rinse water is pumped from the clean tank to the process tank to maintain liquid levels.
