1. Cleaning method of ro membrane filter

At present, the cleaning method of ro membrane filter is divided into online cleaning and offline cleaning. On-line cleaning is a basic cleaning method, mainly used for the maintenance of reverse osmosis system. As we all know, the problem of on-line cleaning is that the content of the cleaning fluid at the rear of the cleaning direction will gradually decrease. At this time, the reverse osmosis membrane should be cleaned offline.

2. Off-line cleaning process of ro membrane filter

①. First, reverse osmosis element membrane that needs to be cleaned is removed and replaced with a spare membrane with excellent performance to ensure that reverse osmosis system does not stop running and to ensure the continuous stability of the entire production process.
②. Test the performance of the membrane.
③. Before cleaning the system, the operating conditions of the system should be grasped, the technical parameters and index values of the reverse osmosis system should be collected, and the original experimental records should be made.
④. According to the customer source water data analysis report, performance test results and system information content, distinguish the entire cleaning process.
⑤. Identification of pollutants. First of all, based on the above analysis results, professional equipment and equipment can be used for further inspection to determine the actual type of pollutants.
⑥. According to the specific analysis results, clarify the required cleaning formula and concentration value.
⑦. In order to better choose the appropriate cleaning formula and cleaning procedure, choose the solution and cleaning method composed of the above cleaning agent, and realize the experimental cleaning of the special cleaning machinery and equipment.
⑧. Clarify the cleaning method and solve the problem of ro membrane filter.
⑨. The cleaned reverse osmosis element membrane enters the test platform for testing and recording. If it does not meet the requirements, it will be sent to the cleaning machinery and equipment for resolution.
The above is the whole content of the cleaning process of ro membrane filter, and I hope it will be helpful to everyone. Timely cleaning can effectively extend the service life of the membrane elements and effectively increase the water output.
