Overview belt filter press sludge dewatering equipment is digested and absorbed an advanced technology research and development. Filter belt and bearings used are high quality pieces. As sewage treatment equipment, filter press sludge dewatering can be treated after flotation of suspended solids and sediment and biological wastewater treatment section of each produced, pressed into the mud cake, achieve the purpose of prevention of secondary pollution, is a good solid-liquid separation equipment; aircraft can be used for slurry concentration, extraction of black liquor as well as for a variety of solid-liquid separation processes. Belt filter press (also known as belt filter press sludge) is mainly used for dewatering biological wastewater treatment and physico-chemical treatment of excess sludge or mixed sludge, its volume is reduced, in order to facilitate further landfill, incineration other treatment, applicable to water supply and drainage, paper, foundry, leather, textiles, chemicals, food and other industries of the solid-liquid separation. After a gravity dewatering zone wastewater treatment plant sludge pumped into the stirred tank mixing of sludge and polymer flocculant (polymer): belt filter press works a three-step filtration and dewatering function , the sludge particles in suspension in the small effect of the polymer by the bridging agent to form a latex agglutination (floc) form larger particles, followed by a gravity flow mode the upper overflow into the stirring tank subsequent dewatering operations. 2, the pressure from the gravity dewatering sludge dewatering zone area into the pressure dewatering zone, down cloth began to squeeze the sludge dewatering. 3, with the cloth sludge dewatering zone pressure moves into the pressurized dewatering zone, in six vertically between the wheel-shaped, according to the diameter of the large wheel getting smaller, the pressure increases by a small configuration, with the upper and lower filter cloth between the different vertical position of the wheel due to conversion of sludge produced and shear force, the floc mud capillary bound water (capillary water) squeezed out to produce a drier sludge cake. FEATURES 1, automatic control, continuously. 2, low energy consumption, long service life. 3, high dewatering efficiency, cake solid rate. 4, easy to manage, easy maintenance. 5, low noise, less chemicals. 6, economical and reliable, wide range of applications. Belt filter press with two filter belt, before the normal pressure dewatering zone and a lengthening of gravity dewatering zone, the unique structure not only improves the efficiency of dehydration, reduced chemicals, but also greatly reduces energy consumption
