Some basic characteristics of reclaimed water reuse

(1) The unique double-layer membrane structure: the pet bait DEAR inorganic ceramic membrane system is used to prepare TiO2 sol on the surface of the membrane filtration layer by sol gel method. The nano TiO2 photocatalytic material is coated on the ceramic membrane by impregnation and pulling method, so that the surface of the ceramic membrane has a "self-cleaning" function, which slows down the organic film surface accumulation and blockage, on the one hand, reduces the membrane pollution, and on the other hand, improves the strength of the ceramic membrane tube. Alumina-zro2 composite membrane structure makes the mechanical properties of membrane tube more excellent. Due to the performance defects of the material itself or some practical problems in the preparation process, a single inorganic membrane material generally can not meet the actual needs. Therefore, the research and development of inorganic loaded composite separation membrane has been developed rapidly, and the polyester bait dearinorganic ceramic membrane adopts integral membrane The Al2O3 ZrO2 composite membrane was prepared by sol-gel method. Because ZrO2 containing material has better mechanical strength, chemical durability and alkali resistance than other materials such as Al2O3, SiO2 and TiO2, pet bait DEAR ceramic membrane has stronger mechanical strength and thermal stability, and the pore size distribution of composite membrane is narrow and single peak.

(2) Due to the unique ceramic membrane structure, the ceramic membrane can be used in on-line water treatment system with stable pressure and high backwash flux It's possible. Polyester baited dear inorganic ceramic membrane is specially designed for sewage treatment. Its biggest feature is its large membrane flux. Its operating membrane flux is 10-100 times of that of organic membrane and 50-10 times of that of ordinary porous ceramic membrane. It has high mechanical strength, pollution resistance and can realize on-line recoil.
