Cleaning method of Ro membrane for water purifier
1, first determine whether the block. 2, to understand the water quality of the region, the main ingredients, such as: calcium, magnesium salt composition of the scale. 3, according to the composition of scale configuration medicine (10% hydrochloric acid), or diluted detergents (scale cleaning agent on the market cleaning), or special RO membrane cleaning agent soak for 24 hours. 4, and then rinse the RO membrane after the bubble, with the ultrafiltration of the RO membrane of high pressure water rinse, rinse off when the water outlet, only open the wastewater outlet.
5, with the ultrafiltration of water from the RO membrane inlet and pure water at the same time high-pressure water rinse, RO water inlet pressure is less than the water inlet pressure from the pure water, but not too much pressure to prevent the Filter broke.
RO membrane is generally backwashing, blocking is too serious to install the pre-protection device, the filter should be replaced. Water hardness in different regions of different hardness of water in northern China and southern limestone areas, the water calcium and magnesium ion content is high, easy to scale, should buy with ion exchange resin filter advanced water purifier. Water containing chlorine, different color smell heavier, more organic content of the city tap water, can choose to buy more activated carbon home water purifier. Because the activated carbon on the water, chlorine, different color smell strong adsorption, the removal of organic matter significant effect.
For urban and rural water quality turbidity of the tap water purification, should buy a coarse filter, fine filter dual function of household water purifiers. For water pollution, requiring complete filtration of any impurities in the water, without heating, direct drinking, should buy reverse osmosis water machine.
