The ceramic filter element has unique functions such as acid and alkali resistance, high temperature resistance, and corrosion resistance. It has been listed as the first choice for the recycling of recycled water in oil, sludge and heavy metal industrial wastewater in this century. It plays a highly efficient and energy-saving role in metallurgy, ultrasound, and groundwater filtration, and is hailed as a membrane product for the water treatment revolution in the 21st century. According to related research, the gradient ceramic membrane with an average pore size of 0.15μm can filter out 100% of pathogenic bacteria such as E. coli, Salmonella, Staphylococcus and mold in the water, as well as rust, red worm and various suspended particles. Through simple mechanical cleaning, the flux can be completely recovered, and the deep pollution without membrane and pore clogging can effectively prevent the re-contamination of purified water. The double control membrane ceramic filter element with a filtration accuracy of 0.1 μm has a longer life. Generally, the filter element must ensure a certain wall thickness to achieve the purification function, and the double control membrane filter element can break through the limit that must ensure a certain thickness.
