Steel Industry

Industry Introduction

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-washing wastewater, wastewater generated by flue gas purification, wastewater generated by cooling equipment, and wastewater from washing sites. According to different production processes, the water quality of wastewater is also different, and the water quality of wastewater discharged from the same process at different times is also very different. The pollution caused by these wastewaters mainly includes: chemical poison pollution, acid pollution, thermal pollution, organic oxygen demand pollution, solid suspended matter pollution, etc., and the pollution surface is very wide. Most of the wastewater discharged from the steel industry is alkaline and has a certain viscosity, which makes wastewater treatment difficult.

Application Field

Converter wastewater, continuous casting wastewater, steel rolling wastewater, pickling wastewater, steel plant comprehensive sewage

Application Advantages

Sudong has developed a special composite rubber plate diaphragm filter press for wastewater treatment in the steel industry. This series of filter presses can effectively separate suspended matter, heavy metals, sediments, etc. in steel wastewater, turning waste into treasure and recycling. The filter plate diaphragm is made of high-quality chloroprene rubber and is molded by a large flat vulcanizer. It has a fast filtration speed, is wear-resistant and corrosion-resistant, has good sealing performance, good pressing effect, lower filter cake moisture content, longer service life, and lower comprehensive maintenance costs.
