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. The reverse osmosis membrane subassembly of current filter core includes the center tube, along the reverse osmosis membrane of center tube circumference winding at the center tube to and the winding is at the seal membrane of reverse osmosis membrane periphery. When the water purifier works, raw water enters from one end of the reverse osmosis membrane, in the process of flowing along the axial direction, one part of water enters the central tube along the radial direction after being filtered by the reverse osmosis membrane, and the other part of water flows into the wastewater waterway from the other end of the reverse osmosis membrane along the axial direction. 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.
