High-quality RO membrane element SP1- 8040 Sea water treatment

Product Details

Reverse osmosis technology belongs to pressure driven membrane separation technology, and the operating pressure is generally 1-10mpa. It intercepts ions or small molecular substances with components of 0.1-1 nm. With the continuous development of membrane technology and the requirements of energy crisis, people have developed ultra-low pressure reverse osmosis membrane, which can be partially desalted under the pressure of less than 1MPa. The representative mass transfer mechanism of reverse osmosis membrane mainly includes dissolution diffusion theory, preferential adsorption capillary flow theory, hydrogen bond theory, Daonan equilibrium model and so on.
