Water temperature is only one factor. 20 degrees is the best state for reverse osmosis. When our factory is the coldest, the water temperature is only 3 degrees, so it can still work, but the water flow is. smaller.
You can check the ORP without adding any reducing agent, and the ORP probe should not be used for more than two years, which means you should confirm that your meter display is correct.
If the conductivity increases rapidly over a short period of time, the conductivity of the raw water and the reverse osmosis membrane should be checked. If the conductivity of the raw water increases, this may be due to increased water consumption or failure of the softening resin in the water softener, and should be analyzed and eliminated. But if this is due to problems with the reverse osmosis membrane (structural damage to the membrane caused by residual chlorine or desioxidants, membrane fouling caused by high hardness, metal oxides, etc., leakage of the O-ring in the membrane, etc.), it is a water treatment failure that needs to be repaired.
