7. Working Principle

TSC20-400 realizes efficient water purification, strong anti-pollution capacity and high desalination rate based on the reverse osmosis principle, combined with anti-pollution membrane material technology, optimized spiral wound structure and wide flow channel design. Osmosis is a natural phenomenon in which water molecules spontaneously flow from a low concentration solution to a high concentration solution. Reverse osmosis applies a pressure greater than the osmotic pressure (1.55MPa) on the high concentration side (raw water side), forcing water molecules to pass through the semi-permeable membrane to the low concentration side (produced water side), while retaining salts, organic matter, bacteria, heavy metals and other harmful substances. The anti-pollution aromatic polyamide composite membrane adopted by this model has a dense structure and an electrically neutral surface, which not only ensures high desalination rate (only allowing water molecules to pass through) but also reduces the adsorption of pollutants, while the wide flow channel design enhances the scouring force of water flow, washes away attached pollutants in time, delays membrane fouling, and ensures stable operation in polluted water environments.
