Are you talking about on-line or off-line cleaning of reverse osmosis membranes? "Xin Gerry" standard reverse osmosis membrane online cleaning basic steps? Yes:
1, reverse osmosis membrane online cleaning thoroughly wash the cleaning system in the tank.2, the installation of new cartridges or filter bags in the filter cleaning system. 3, to the cleaning tank to add reverse osmosis product water to the appropriate level.?
4, reverse osmosis membrane on-line cleaning at a ratio of 1 pound (0.4 kg detergent) and 10 gallons (37.85 liters of water) and KOCHKLEEN?PA acidic cleaning agent mixed into the cleaning tank.?
5, reverse osmosis membrane on-line cleaning needs to be recycled cleaning fluid through the security filter back to the tank, until the cleaning fluid is completely mixed.
6, reverse osmosis membrane on-line cleaning needs to be heated to 25-30 degrees cleaning solution.
7, reverse osmosis membrane on-line cleaning need to test the cleaning solution PH value, suitable range between 2-3. If you need to reduce the PH value can continue to add cleaning agent, adjusted to the appropriate range.
8, reverse osmosis membrane on-line cleaning needs in the cleaning equipment system operation, read reverse osmosis product water and concentrated water PH value, make a good record, in order to prepare for the cleaning of the reference use.
9, reverse osmosis membrane online cleaning need to slowly open the cleaning pump, cleaning flow and set to the correct value of the cleaning fluid into the cleaning equipment, while observing the concentrated water discharge outlet water quality changes, when clearly observed when there is a cleaning fluid discharged, test the PH value of the need to be adjusted according to need to circulate cleaning fluid for 30 minutes. At any time to detect the PH value of the cleaning solution at any time to increase the pharmaceutical regulation.
10, reverse osmosis membrane cleaning online need to turn off the cleaning pump, will be retained in the membrane system static immersion 30 minutes.
11, re-open the cleaning pump, continue the cycle of cleaning if the cleaning fluid discoloration or dirt content is serious, the cleaning fluid should be re-formulated, and observe the pressure drop of the security filter, the pressure drop is greater than 1 kg must be replaced when the filter element.12, reverse osmosis membrane online cleaning needs to be cleaned in the program to observe the cleaning equipment in the membrane element water production, concentrated water flow and so on in the reverse osmosis membrane cleaning I suggest and so on. Reverse osmosis membrane cleaning is a more professional cleaning, if there is a need in this regard, it is recommended to find some professional enterprises to do, the above is only "XinGeRui" reverse osmosis membrane cleaning standards for reference only.
