Q:How long is the service life of the membrane?

There is no fixed service life for the membrane. Generally, it lasts 1-2 years. The actual service life depends on factors like raw water quality, water consumption, the ratio of pure water to wastewater of the equipment, pre-filter media, and the operating pressure of the equipment all of which affect the lifespan of the RO membrane.
