Microporous membrane materials is the use of polymer chemistry, pore additive special treatment applied to the support layer made of. In membrane separation technology, the microporous membrane is the most widely used of a film breed, easy to use, fast, has been widely used in many fields of scientific research, food testing, chemicals, nanotechnology, energy and environmental protection. Its filter size of about 0.1um-50um. Sale microfiltration equipment cracking process characteristics: ① can achieve automatic control operation; ② binding membrane material itself superior mechanical properties, using international advanced technology and backwash air and water cross-flow processes; ③ water treatment industry as RO, NF membrane The pre-treatment equipment, RO, NF influent SDI≤2, greatly extend the RO, NF membrane elements of life, to ensure stable operation of membrane systems for a long time. ④ small footprint. Traditional conventional methods through a complicated process because of the need to reach RO / NF's water requirements, and continuous microfiltration process one step filtering process can get high-quality pre-treatment of water used directly as RO / NF water. ⑤ good water quality. Removal of water turbidity, suspended solids, total bacteria and E. coli good water SDI≤2. Low investment costs. Reduce the pre-treatment equipment, thereby reducing the cost of equipment and pharmaceutical inputs. ⑥ extend the cleaning cycle RO / NF system. Make RO / NF system cleaning cycle from the traditional 1-3 months to more than six months, from the traditional life of 2-3 years was extended to more than five years. System advantages cracking Searle microfiltration equipment ① using polyvinylidene fluoride (PVDF) hollow fiber membrane, the membrane flux ② long life high water stability ③ low demand for the raw water quality, water production meet the water requirements SDI RO system ④ system is a high degree of automation, simple operation, small footprint, low maintenance and operating costs Applications: ① ② residential tap water sterilization and purification ③ ④ water utilities to groundwater or surface water for water purification treatment ⑤ new sources of water pre-pre-treatment of municipal wastewater treatment ⑧ ⑨ explore ⑥ ⑦ reverse osmosis desalination pretreatment pretreatment, large-scale reverse osmosis filtration system through biological treatment of sewage in order to achieve the purpose of reuse ⑩ industrial water purification industrial cooling water reuse
