Horizontal belt filter press with S-shaped belt arrangement, sludge pressure gradually increases and eases. Suitable for dewatering both organic hydrophilic materials and inorganic hydrophobic materials. Due to the extended settling zone length, this series of filter presses has extensive experience in dewatering various materials. Special designs are implemented on the belt filter presses for specific sludge characteristics in industries such as dyeing and printing, electroplating, papermaking, chemical, urban wastewater, mining, heavy metal, leather, drilling, brewing, food, aluminum, oil refining "three sludge," synthetic fiber factory float sludge, ceramic polishing wastewater sludge, beer factory biochemical sludge, soda ash sludge, hydrometallurgy sludge, electrolytic manganese dioxide sludge, fermentation sludge, starch sludge, pyrite mine sludge, calcium carbide slag sludge, kaolin sludge, cement plant sludge, coal washing plant coal sludge, sintering concentration large mine sludge, steel mill tail sludge, steel mill converter sludge, and steel mill blast furnace gas sludge, to help clients increase wastewater treatment capacity, reduce sludge moisture content, and lower operational costs.
