AI Technical Summary
When cleaning the reverse osmosis membrane, it is difficult to effectively solve the problem of flux reduction caused by membrane pollution, and the cleaning cost is high, which affects the deep treatment effect of recycled water and wastewater.
A hydrogen-containing membrane cleaning device was designed. The hydrogen gas was mixed with the cleaning water through an air-water mixing pump to form micro-nano hydrogen bubbles. The high diffusion of hydrogen was used to penetrate the contaminants on the membrane surface, and combined with the design of multiple filtration and recycling, the cleaning effect was improved.
It effectively improves the flux and cleaning effect of the membrane, reduces the cleaning cost, achieves efficient and economical cleaning of the reverse osmosis membrane, and extends the service life of the membrane.
