Application of PET isolation film in various industrial production-film suppliers
In various industrial productions, PET isolation membranes usually involve molecular-level concentration and separation processes. 1. Application in environmental protection and water resources. Membrane technology has been widely used in wastewater treatment, pollution prevention and comprehensive utilization of water resources. In many cases, not only waste water is treated, but useful substances and energy can be recovered. 2. Treatment of various oily wastewater and waste oil ① Treatment of oil recovery reinjection water: The membrane method can remove the emulsified and dissolved oil in the water and improve the quality of the injected water. ② Treatment of oily wastewater: Many industrial production and transportation industries produce a large amount of oily wastewater. Membrane filtration technology is the most effective way to meet discharge standards. ③Purification of waste lubricating oil: using conventional technology and membrane separation, very pure lubricating oil can be obtained, which is suitable for the treatment of waste engine oil such as automobiles. ④ Purification and recovery of machine tool cutting oil: The membrane method can remove bacteria and impurities in the waste cutting oil, and reuse it after treatment. ⑤ Purification treatment technology of waste edible oil: Edible oil produces carcinogens under continuous high temperature, which can be removed by membrane method. pet insulating film ⑥ purification of edible rapeseed oil: rapeseed oil contains 15% to 48% erucic acid with high carbon content. It can be removed by membrane method, up to the standard (sinapic acid <5%). 3. Wastewater treatment and reuse ①The membrane bioreactor treats domestic sewage and reuses middle water. It has a small area, low equipment investment and good water quality. ②The treatment and reuse of printing and developing wastewater can be discharged up to the standard by adopting membrane technology, and it can also be recycled. ③The electroplating wastewater can be treated by membrane technology, the water is reused, and the pollutants are returned to the tank for use. ④Dyeing wastewater is separated by membrane to remove colored dyes, and the obtained water is reused. Denim printing and dyeing wastewater can recycle indigo fuel. ⑤The membrane used for papermaking wastewater can separate the lignin and pigments in the wastewater, and the purified water can be discharged or reused.
