Serfilco’s Series ‘DF’ for unattended operation 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. Available in carbon steel, 316 stainless steel, CPVC or polypropylene, the unit is used in industries such as process water, phosphating/parts washers, and water wall spray booths.
