Reverse osmosis water treatment device effluent pH value is higher than 5? (1) the hydrolysis of cellulose acetate membrane is easy to cause deterioration of the performance of the reverse osmosis device. For this reason, the pH value of the water must be strictly controlled, and the pH value of the water supply must be maintained at 5-6, and the composite film can be PH3-Run under the PH11 range.(2) when the amount of secondary sodium injection is insufficient and the free chlorine in the water supply cannot be measured, there will be sticky mud on the membrane assembly of the reverse osmosis device, and the pressure difference of the reverse osmosis device will increase.However, for composite films and polyamide films, the amount of free chlorine entering the membrane assembly must be strictly controlled, and exceeding the specified value will lead to oxidation and decomposition of the membrane.(3) if the water with the F1 value exceeding the standard is supplied to the reverse osmosis device as t
