With the widespread application of water purification equipment in the water treatment industry, reverse osmosis membranes are gradually being valued. The cost of reverse osmosis membranes is one of the most concerned issues for consumers. Good maintenance can help extend the service life of reverse osmosis membranes.
After the equipment test runs, we protect the reverse osmosis membrane in two ways. The equipment test machine runs for two days (15-24h), and then uses 2% formaldehyde solution for maintenance; or after 2-6h operation, uses 1% NaHSO3 aqueous solution to maintain the reverse osmosis membrane (the air in the equipment pipeline should be exhausted , To ensure that the equipment does not leak, close all inlet and outlet valves). Both methods can achieve satisfactory results. The first method is more expensive and is used when the idle time is long, and the second method for maintaining the reverse osmosis membrane is used when the idle time is short.
