NOVELTY - A reverse osmosis membrane element comprises a shell (1), a filter unit and a water inlet pressurizing unit (3). The filter unit used for purifying water and forming nutrient solution, is fixedly installed in the shell which is a cylindrical hollow structure. The water inlet pressurizing unit slidingly provided between the filter unit and the shell, is used for absorbing water and pressurizing. USE - Reverse osmosis membrane element is used for purifying water and producing nutrient -rich drinking water. ADVANTAGE - The reverse osmosis membrane element enables to obtain nutrient-rich pure water suitable for drinking. The reverse osmosis membrane is not damaged during sealing and circulating of pure water, due to stress and deformation.
