Reverse osmosis membrane
Ordinary reverse osmosis membranes can withstand free chlorine attack about 1000ppm·h, and the residual chlorine in the influent water of membrane elements is required to be <0.1ppm It must not contain oxidizing substances, otherwise the membrane elements will be oxidized; and the anti-oxidation reverse osmosis membrane is resistant to free chlorine attack About 26000ppm·h (the desalination rate is still >98%), if the residual chlorine in the influent = 0.5ppm, the membrane element can still be used for 3 years Maintain a salt rejection rate of over 98%. Since the oxidation resistance of the anti-oxidation film is much higher than that of the ordinary film, the pre-treatment In the treatment, the treatment unit for removing residual chlorine (or other oxidizing substances) can be omitted when using anti-oxidation membrane elements. Reduce investment.
