Belt Filter Press is a bio-solids/sludge dewatering device that applies mechanical pressure to a chemically conditioned slurry, which is sandwiched between two tensioned belts, by passing those belts through a serpentine of decreasing diameter roll RBYL series belt (type) filter press is a kind of dewatering machine developed on the basis of advanced foreign technology. It features large treating capacity, high dewatering capacity and long life time. As a part in waste water treatment system, it is used for dewatering of suspended particles and residue after treated so as to avoid secondary pollution. It is also applicable for treatment of thickner concentration and black liquor extraction. Functional Principle: Most Belt Filter Press operations can be divided into three general stages - initial de-watering, which makes the sludge pulp; pressing or medium pressure filtration, which conditions the sludge for high pressure filtration quality; and high pressure filtration, which raises the dry solids content in the sludge cake to the optimum. The process begins as the sludge enters the press, where it is mixed with a chemical , either in the press, or in a conditioning tank prior to the press. From this flocculation or preparation zone the sludge enters the gravity drainage zone, where a large rotating drum agitates the floc and drains approximately 70% of the free water. The resulting capture rate can be as high as 99%. Features and Advantages: The features that enable a Belt Filter Press to achieve substantially higher production rates and produce high cake solids at discharge are:The use of the high rate drainage plow technology in the gravity zone. 1.A wedge section with an adjustable angle of conversion of the belts. 2.A large initial drum in the pressure/shear zone. 3.An extended length pressure/shear zone. 4.A choice of 2 belt or 3 belt dewatering systems. 5.Larger standard filtration areas for greater process throughput and higher cake consistency. 6. A patented high rate drainage system that dramatically improves filtration rates. 7.An easily adjustable, variable wedge compression zone that maximizes process rate and performance. 8. A high performance, larger to smaller drum pressure profile for higher cake solids concentration. 9. High quality structural frame materials and components for trouble-free, long lasting operation.
