How they Work:
After proper polymer conditioning, sludge is fed to the BFP where initial dewatering takes place in the horizontal gravity section. Sludge is then trapped between two belts, first through a wedge area and then through two low-pressure curved static wedge wire screens. Sludge then continues over and below two medium-pressure wedge wire drums and finally through six solid high-pressure drums. Scrapers then discharge the dewatered cake. Each belt is then pressure-washed with water before returning to its initial position. Wash and filtered water is collected and drained onto a concrete basin. Unit can also be optionally provided with an own stainless steel basin.
NAHUELCO'S FPB Belt Filter Presses are available in 1.0, 1.5 and 2.0 meter belt width configurations.
Typically, a belt filter press receives sludge ranging from 2 - 4 % feed solids and produces a final product of 12 - 20 % cake solids. Performance depends on the nature of the solids being processed.
Applications Municipal: Raw and anaerobically digested sludge (Primary, WAS, etc.), Aerobically digested sludge (Oxidation ditch, Primary & Activated sludge, WAS, etc.)
Industrial: Food Processing, Pulp & Paper, Chemical industry sludge Pharmaceutical industry sludge, Industrial waste sludge, etc. |
