Storage of Membrane Elements in Reverse Osmosis Equipment
1. Membrane components should not be sealed by water treatment equipment manufacturers before they are loaded into pressure vessels. They should be stored in a cool and dry place and should not be frozen.
2. Installation of Membrane Components
Before installing membrane components, it should be ensured that the system Hangzhou water treatment equipment has completed cleaning work.
When the membrane components are loaded into the system, O-rings and concentrated water sealing rings should be properly lubricated. Silicon-based reverse osmosis water equipment glue or 50% glycerol aqueous solution can be used. Oil, grease, Vaseline or petroleum compounds are prohibited.
3. Rinse of New Membrane
After installing the membrane elements, the new system should wash the reverse osmosis water equipment thoroughly, and the residual impurities, solvents and protective liquids in the system should be cleaned completely.
4. Issues needing attention in the start-up and operation of the system
Thick water valves should be kept fully open before the system is started. After starting the system, the concentrated water valve can be closed slowly, so that the system can achieve the set recovery rate. It is strictly forbidden to start the equipment when the concentrated water valve is closed.
During the operation of the system, the valves in the production pipeline should not be closed at any time.
Before high-pressure operation, low-pressure flushing is carried out through soft start mechanism or frequency conversion speed regulation to discharge air.
