Maintenance of RO membrane in ultrapure water machine accessories

In the process of using the ultra pure water machine, users have the problems of parts maintenance and repair The maintenance and repair of RO desalination membrane is particularly important RO pure water machine can also be called reverse osmosis pure water machine Reverse osmosis pure water equipment mainly uses reverse osmosis membrane for water desalination How to maintain this pure water equipment in daily use? The following are several common methods:   use chemical method to clean RO membrane of pure water machine 1 Adding enzyme detergent, using enzyme detergent to deal with the membrane, is particularly effective for the pollution of organic matters, especially protein, oil and other organic matters If the cleaning effect is better at 50 ℃ - 60 ℃, generally, use 1% enzyme detergent to clean the membrane at low pressure after 10 days or half a month of operation As the concentration of enzyme detergent is low, the immersion time is required to be longer 。 Under high or low pressure, citric acid solution is used to wash the membrane continuously or circularly with 1% - 2% citric acid solution This method has a good cleaning effect on Fe (OH) 3 pollution 2 Concentrated salt water is effective for cleaning the membrane severely polluted by the body This is because the high concentration of salt water can weaken the interaction between the colloids and promote the colloids to agglomerate and form micelles 3 Hydrogen peroxide solution, for example, dilute 0.5L, 30% H2O2 with 12L deionized water, and then clean the membrane surface This method is particularly effective for organic pollution 4 The water-soluble emulsion is very effective for cleaning the membrane polluted by oil and iron oxide, generally 30-60 minutes Cleaning with physical principles The simple physical cleaning method is to wash the membrane with low pressure and high flow rate through water for 30 minutes, which can restore the permeability of membrane to a certain extent, but after a long time, the permeability is still reduced, and the membrane surface can also be washed with water and air mixture under low pressure for 15 minutes, which is effective for cleaning the membrane polluted by organic matters at the initial stage The above is the maintenance method of RO desalting membrane in ultra pure water machine accessories For more questions, please call the customer service of the manufacturer for consultation.
