Reverse osmosis pure water making machine membrane element how to offline cleaning

In reverse osmosis making machine run normally, trouble-free, reverse osmosis systems generally use online cleaning and maintenance, the impact of sterilization and protection on a regular basis. But, if when the reverse osmosis membrane element severe pollution, on-line cleaning is powerless, this time you need to reverse osmosis membrane element offline cleaning. Reverse osmosis membrane element, as a deep filtering method, the surface would inevitably residue colloid, microorganism, impurity particles and difficult to soluble salts in the glaze Su pestle or surface precipitation, therefore, use the reverse osmosis device in a variety of areas, once put into use, in the end need to be cleaned, just different from the length of the cleaning cycle. The following will introduce the reverse osmosis membrane offline cleaning of specific methods and steps. Step 1: replace with good performance of alternate membrane element on the reverse osmosis system for cleaning membrane element, to ensure that the reverse osmosis system does not stop running, guarantee the stability of the whole production process of continuous. The second step: reverse osmosis membrane element performance test ( This step is important) : for every one membrane element separately to test various performance indicators, including: desalination of horseshoe crabs fruits You rate, water rate, pressure difference and bandits dog zhi chi, quantity, and make a good record of test before. Desalination rate, water rate and differential pressure test condition: conform to the standards of different types of film makers *. Step 3: system to understand the status of the system is currently running before cleaning; Step 4: collect run the parameters of the reverse osmosis system indicators, make original records; Step 5: according to user's raw water analysis report, the performance test results and the understanding of system information judgment cleaning process; Step 6: identification of pollutants. First initially determined according to the analysis of the fifth step, then through the production of special machine, instrument for further verification, to determine the specific types of pollutants. Step 7: according to the analysis of the fifth step, step 6, determine the required cleaning formula. When RO membrane pollutants is determined, we can choose membrane keener trent building manufacturers * series formula, choose the suitable one or two formula; Or choose new-type computer rubbing grave cruise choose the special formula ( When the RO membrane is special pollutants, inefficiency of using the ordinary formula, or from the perspective of economy, the special formulation is more economic) 。 At home and abroad at present, there are a lot of reverse osmosis membrane element cleaning special agents, such as kaiyuan hengye KY series cleaning agent and bactericide, according to the author's experience, the use effect is good, and compared to traditional medicament, economy is good too. Step 8: the special cleaning production machine with the reverse osmosis above detergent combining physical cleaning method to clean a pilot, to select the appropriate cleaning formula and the program; Step 9: make sure the cleaning method, to deal with all these membrane element; Step 10: after the cleaning of membrane element into the testing platform for testing and record, do not conform to the requirements of clean back into making machine for processing; Data cleaning, cleaning summary report.
