Background

The 10nmMBR membrane component is mainly applied to drinking water purification, sewage treatment, industrial water treatment, beverage, biology, food, medicine, environmental protection, chemical industry, metallurgy, petroleum, thermal power and other aspects. The production process of the 10nm MBR membrane module mainly comprises the steps of filling thousands to tens of thousands of hollow fiber membrane filaments in a special membrane filament pouring box, pouring epoxy resin or polyurethane glue into the pouring box, and performing cutting, water collecting box bonding and other processes to form the complete 10nm MBR membrane module.

If the 10nm MBR membrane module is not stored or is not used properly in the using process, membrane threads are easy to dry, and micropores on the surface of the membrane threads shrink or disappear, so that the flux of the membrane module is reduced or even has no flux. And in the other situation, a membrane wire drying treatment process is adopted in the membrane wire production process, so that the membrane component is convenient to seal and pour at the later stage, and after pouring is finished, the membrane wire flux is recovered by adopting hydrophilization, cleaning and hole-protecting treatment processes, so that the aim of normal use is fulfilled.
