Reverse osmosis membrane is a key component of pure water treatment equipment. Reverse osmosis membranes are receiving increasing attention from people. Due to the high price of reverse osmosis membranes, how to extend their service life has become one of the concerns of users. Regular maintenance is beneficial for increasing usage time.

The reverse osmosis membrane separation technology in purified water equipment is a technique for separating solutions at room temperature, suitable for the separation and concentration of substances sensitive to heat sources. Compared to previous separation methods, it consumes less power. The reverse osmosis membrane separation technology has good effects, high desalination and recovery rates, and can capture nanoscale particle substances.

Unused pure water equipment reverse osmosis membrane components are usually soaked in 1% sodium bisulfite and 18% glycerol aqueous solutions, and then stored in closed plastic bags. It can be stored for about a year without damaging the plastic bag, and repeated use will not affect its service life and performance. Please use the plastic bag as soon as possible when opening it.

After debugging the pure water treatment equipment, two methods can be used to protect the reverse osmosis membrane. After two days of operation, maintain the equipment with a 2% formaldehyde solution. Alternatively, after running for 2-6 hours, the reverse osmosis membrane elements should be kept in a 1% sodium bisulfite solution. Both methods can achieve satisfactory results. But firstly, it has high cost and can be used after long-term equipment shutdown. Secondly, it can be used after short-term shutdown.
