AI Technical Summary
Traditional reverse osmosis membrane systems suffer from severe membrane fouling, low mass transfer efficiency, high operating energy consumption, frequent chemical cleaning, and difficulties in the application of nanobubble coupling, resulting in poor system stability, high energy consumption, high cost, and significant environmental pollution risks.
By integrating nanobubble generation and uniform injection, membrane material functionalization modification, and online adaptive cleaning, a system is established. Through the synergistic effect of the nanobubble generation module, reverse osmosis membrane module, and online cleaning module, gas-liquid-membrane three-phase synergy is achieved, improving mass transfer efficiency and extending membrane life.
It increases water flux by 30%-50%, reduces operating pressure by 20%-30%, reduces the frequency of chemical cleaning and the use of chemicals, extends the life of membrane modules, reduces energy consumption and operation and maintenance costs, and achieves efficient, low-consumption and long-lasting reverse osmosis water treatment.
