Reverse osmosis device is the most important parts in the reverse osmosis membrane, its main principle is above solution and the effect of osmotic pressure, on the basis of other material can't through a semipermeable membrane will leave to the material and water. Reverse osmosis membrane membrane pore size is very small, so can effectively remove the water soluble salts, colloid, microorganism and organic matter, etc. Reverse osmosis equipment system has good water quality, low consumption, no pollution, industrial is simple and convenient operation, etc. Below for everyone to introduce: reverse osmosis equipment of RO membrane cleaning? Prepare the material: acidic reagent ( Citric acid) : 25 kg, alkaline reagents ( Sodium hydroxide) : 25 kg, PH paper: 1 a, the first to use acid reagent to clean: 1, in washing membrane 200 - into my medicine cabinet 300 l water; 2. Add 2 - in the water 3 kg citric acid adjustment, with the PH test paper test, water quality need to be in 1 - Between the two, If it is beyond the scope of the, can continue to a small amount of adding citric acid, until the water quality in the 1 - 2) ; 3, circulation cleaning, according to wash the membrane process on 1 - cleaning 2 h, 10 - downtime After 15 min, continue to open washing membrane device, 40 - continue to cleaning Put the cleaning fluid after 60 min, clean, and then with pretreatment of water to wash, rinse water quality with PH test paper test, the water quality to neutral ( 6 - 7) between , if the water quality does not meet the range of neutral, flushing, needs to be continued until the water quality standard. About the cleaning process must be 3 h. Other water increases, the pressure to reduce, the need for cleaning in alkaline reagents. Second, the alkaline agent cleaning infuse 200-1, was washing membrane yuexiang 300 l water; 2. Add 2 - in the water Adjusted 3 kg of sodium hydroxide, with PH test paper test, the water quality needed in September 10, ( If it is beyond the scope of the, can continue to a small amount of naoh addition, until the water quality in September 10) ; 3, circulation cleaning, according to wash the membrane process on 1 - cleaning 2 h, 10 - downtime After 15 min, continue to open washing membrane device, 40 - continue to cleaning Put the cleaning fluid after 60 min, clean, and then with pretreatment of water to wash, rinse water quality with PH test paper test, the water quality to neutral ( 6 - 7) between , if the water quality does not meet the range of neutral, flushing, needs to be continued until the water quality standard. About the cleaning process must be 3 h. Note: 1, water quality, it must rinse clean and with PH test paper test, the water quality to achieve neutral - 6 7, if without rinse clean for the next step of operation, will cause the scale formation in inner of uv water purifier equipment, influence the production. 2, pay attention to keep the water temperature rise to more than 45 ℃, in order to avoid damage to the RO membrane, such as found that the water temperature rise to more than 45 ℃, should stop, wait for after cooling to run again. Reverse osmosis equipment need regular cleaning, directly related to the equipment by the quality of reverse osmosis membrane system effect of water quality is good or bad. Promised to use all of the parts are new, not shoddy.
