Metal cleaning waste water zero discharge cleaning equipment DTRO membrane offline and online cleaning methods Author:? Industries as an important basic conditions for progress and development of human society, I believe we all know, the industrial sector can cause pollution of water resources, especially for metal cleaning The environment is also a kind of destruction. Everyone will choose metal cleaning wastewater zero discharge equipment. As time goes by during the use of metal cleaning wastewater zero discharge equipment, DTRO membrane elements will gradually become fouled. Depending on the degree of pollution, it will be necessary to shut down for offline cleaning if necessary. An operation is very important, so it is necessary to understand the cleaning specifications. Let's take a look at the offline cleaning method of the special DTRO membrane element for the metal cleaning wastewater zero discharge equipment. 1. Replace the membrane elements to be cleaned on the DTRO reverse osmosis system with spare membrane elements with excellent performance to ensure that the zero discharge treatment system of metal cleaning wastewater does not stop running and ensure the continuous stability of the entire production process. 2. Test the performance of DTRO reverse osmosis membrane elements. 3. Before cleaning the dedicated DTRO membrane element for metal cleaning wastewater zero discharge equipment, understand the current operating status of the system, collect and run the DTRO reverse osmosis system parameters, and record the original data. 4. Judging the cleaning process according to the user's raw water analysis report, performance test results and the information of the zero discharge treatment system for metal cleaning wastewater. 5. For the identification of pollutants, preliminary judgment is made based on the analysis results of 3 and 4, and further verification by special equipment and appliances to determine the specific pollutant types. 6. According to the analysis results, determine the required cleaning formula and concentration. 7. Use the above cleaning agent combination treatment cleaning methods on the DTRO reverse osmosis special cleaning equipment to perform experimental cleaning to select the appropriate cleaning formula and cleaning procedure. 8. Determine the cleaning method and treat all membrane elements. 9. Test and record the cleaned membrane elements. Those that do not meet the requirements will be sent back to the cleaning equipment for processing.
