Description

TECHNICAL FIELD

[0001] The utility model relates to drinking water filtration technical field, specifically a kind of reverse osmosis RO device. BACKGROUND

[0002] RO membrane, that is, reverse osmosis membrane, is a kind of semi-permeable membrane for water treatment, which can filter out impurities such as dissolved salts, colloids, microorganisms and organic matter in water; its pore size is very small, usually made of high polymer material, usually RO membrane is made into filter core when used, and the filter core is connected to the filtering equipment, so that the water flow is filtered by the filter core. However, due to the very small pore size of RO membrane, the filtering efficiency is low, which requires a pressure pump to provide pressure for the water flow to make the water flow be squeezed through the RO membrane for filtering. However, the RO membrane core is usually rolled into a cylinder and fixed on the filter cartridge, and the RO membrane covering area is large, which has high cost.

[0003] In addition, RO membrane is easily polluted by inorganic scaling, organic adsorption and microbial breeding, which may cause membrane flux decline and desalination performance degradation. For example, some RO membrane materials, such as cellulose acetate membrane, will hydrolyze over time, causing the desalination rate to gradually decrease, and are more susceptible to microbial attack, losing functionality and integrity, resulting in the need to replace the RO membrane after a certain period of use. When replacing, the filter core needs to be disassembled, which is inconvenient. UTILITY MODEL CONTENT
