The water treatment adopts pure physical methods such as ultrafiltration membrane filtration, which can reasonably filter the rust, fine sand and bacterial viruses in the water, preserve the minerals and nutrients in the water, and the effluent water body is similar to pure water. The technical performance of uf membrane filter makes the germ filtration rate reach 99.999%, and the virus infection sludge load reaches 99.99%. The entire filtration process does not need to add chemical disinfectants, this purely physical filtration method can bring you safe and reliable domestic water.
Ultrafiltration membrane used in paper industry wastewater, it is mainly to concentrate and recover certain components, and the passed water returns to the processing process. The scientific research on membrane separation of general papermaking industry wastewater specifically involves the development and utilization of recycling by-product lignin, the pre-concentration of papermaking wastewater, and the removal of toxic substances in bleach wastewater.
Oily wastewater is divided into floating oil, dispersed oil and emulsified liquid. The first two are relatively easy to solve, and can be solved by mechanical equipment separation, condensation deposition, activated carbon filtration and other technologies to reduce the oil to a very low level. However, emulsions have surfactants and organic compounds with the same functions. There are millimeter-sized positive ions in water, which makes it difficult to force separation and coarse-graining. Use ultrafiltration membrane technology to remove COD and BOD from water and organic compounds with low molecular structure through the membrane, thereby completing the separation of water and oil.
