Belt filter press is a new type of continuous operation solid-liquid separation equipment. The four stages of pretreatment, gravity dewatering, wedge-shaped area pre-pressing dewatering and pressing dewatering of the belt filter press are filtered into mud cake. The mud cake after pressure filtration can not be squeezed without water, and can be directly loaded and transported. It has the characteristics of large processing capacity, high dehydration efficiency and long service life. It is an ideal equipment for environmental management and resource recovery.
The working principle of belt filter press:
After the concentrated sludge is fully mixed with a certain concentration of flocculant in a static and dynamic mixer, the tiny solid particles in the sludge are aggregated into larger flocculent agglomerates, and free water is separated at the same time. The sludge is transported to the concentrated gravity dewatering filter belt, and the free water is separated under the action of gravity to form a non-flowing sludge, which is then clamped between the upper and lower mesh belts, and passes through the wedge-shaped pre-pressing area and low pressure. Under the action of extrusion force and shear force from small to high pressure area, the sludge is gradually squeezed to achieve a greater degree of sludge and water separation, and then form a filter cake for discharge.
Main applications of Belt Filter-Presses:
*Municipal wastewater treatment plants
*Food and processing industry
*Pulp-and-paper mills
*Leather and metallurgical industry
*Waste treatment facilities of water conditioning and purification
*Biogas complexes
