Description

Membrane module for sewage treatment

Technical Field

The utility model relates to a water filtration technology field especially relates to a membrane module for sewage treatment.

Background

The reverse osmosis technology is widely applied to the water treatment industry, and the working principle of the reverse osmosis technology is that the pressure difference between the front and the back of a membrane is used as a driving force, and the separation of a solvent and a solute is achieved by utilizing the selective permeability of the membrane. Due to the selective permeability of the membrane, solutes in the influent water are concentrated on the surface of the reverse osmosis membrane to form precipitates which adhere to the surface of the reverse osmosis membrane or block the pores of the reverse osmosis membrane, resulting in contamination of the reverse osmosis membrane and a decrease in the permeability. Due to the difference of the quality of the inlet water, substances polluting the reverse osmosis membrane comprise various hydrated metal oxides, carbonates, sulfates, silicic acids, organic matters, microorganisms and the like.
