At present, in the steel industry, where energy consumption accounts for 10% of the total energy consumption, water consumption accounts for about 9%. The main sources of wastewater generated by the steel industry are: slag flushing wastewater, wastewater generated from purifying flue gas, wastewater generated from cooling equipment, and wastewater from flushing sites. According to different production processes, the quality of wastewater also varies, and the quality of wastewater discharged from the same process at different stages also varies greatly. The pollution caused by these wastewater mainly includes chemical poison pollution, acid pollution, thermal pollution, organic oxygen demand pollution, solid suspended solids pollution, etc., with a very wide range of pollution. The discharge of wastewater from the steel industry is mostly alkaline and has a certain viscosity, making wastewater treatment difficult.

Sudong has developed a specialized composite rubber plate diaphragm filter press for the treatment of wastewater in the steel industry. This series of filter presses can effectively separate suspended solids, heavy metals, sediment, etc. in steel wastewater, turning waste into treasure and recycling. The filter plate diaphragm adopts high-quality chloroprene rubber formula and is molded by a large flat vulcanization machine. It has fast filtration speed, wear resistance, corrosion resistance, good sealing performance, good pressing effect, lower moisture content of the filter cake, longer service life, and lower comprehensive maintenance costs.
Rubber diaphragm plate filter press, rubber plate filter press, polypropylene diaphragm filter press, etc
Adopting PLC program control, with high degree of automation, convenient operation, and reliable performance; Engineering design, integrated control, energy-saving and efficient; The rubber diaphragm plate is made of high-quality chloroprene rubber, and the sealing surface of the filter plate has elastic contact and good sealing performance; Adopting full rubber diaphragm plate pressing, the filter cake has low moisture content, and the diaphragm pressing pressure can reach 1.6MPa. The processing capacity is large, and the steel framework of the filter plate can be reused multiple times, resulting in high comprehensive economic benefits. The application of rubber diaphragm plate filter press effectively improves treatment efficiency, reduces the moisture content of mud cake, and reduces equipment maintenance costs.
