Totally automatic fabric filtration system intended for use with unattended operation. The system automatically indexes media for continuous filtration, even with varying input or solids content. Contaminated solution is pumped to the diffuser tray, which distributes flow across the full width of the filter bed. Particle separation starts immediately via gravity flow through the media to the clean reservoir below the conveyor frame. Filtered solution can then gravity-drain to waste or be returned to the process via a pump. Consumed fabric is advanced to the sludge box as fresh media is simultaneously indexed to the solution flow. The unit is utilized in various industries, such as Industrial Wastewater, Processor Cooling Water, Machine Tool Coolants, Phosphating/Parts Washers, Water Wall Spray Booths and Treated Plating Waste. It is available in carbon steel, 316 stainless steel, CPVC or polypropylene, in sizes from 1.5 to 113 sq. ft. of filter surface area and flow rates to 650 GPM @ 80 micron.
