For example, the TDS value of raw tap water is 400 ppm, and the purified water is 40 ppm, so the desalination rate of the RO membrane of this equipment is 90%. How to judge the need to replace the RO membrane? The TDS value is significantly higher than usual, or the salt rejection rate is significantly reduced. If there is no other reason, it may be that the life of the RO membrane of the machine has expired and should be replaced.
