DSP Screw Press

BDP developed this screw press specifically for Biosolids dewatering to provide high capacity, excellent solids capture, in a fully enclosed system with automated simple operation. Features: Independent Pre-Thickening with Rotary Drum Concentrator Slotted Screen: higher open area and smaller opening for improved capture, reduced plugging Filtrate Recycle/Polishing: produces solids capture over 95% Replaceable Flight brushed without removing screw auger. Tapered Screw: Reduces Distance for Filtrate Flow for increased capacity, less rotational force on material – Less…
