Belt Filter/Rotary Presses - Pre-thickening screw press

The DSP Screw Press from BDP Industries offers pre-thickening with a rotary drum concentrator. A feed flow of 100 gpm at 0.8 percent solids will thicken to 5 percent solids, reducing the flow to the screw press to 16 gpm (84 percent). It offers pressurized feed to the screw auger via the thickened biosolids transfer pump. Its slotted screen provides a large filtration area and effective liquid extraction. A tapered shaft screw auger compresses the slurry. A filtrate recycle system improves solids capture. 518/527-5417;
