(1) New film (before use)
①The membrane element must always be kept in a wet state. Even when it is necessary to temporarily open the same package to confirm the quantity of the same package, it must be in a state without puncturing the plastic bag. This state should be stored until the time of use.
②When storing in an atmosphere over 10℃, avoid direct sunlight and choose a well-ventilated place. At this time, the storage temperature should not exceed 35°C.
③If it freezes, it will be physically damaged, so take heat preservation measures and don't freeze it.
(2) Membrane element after passing water
①The membrane element must be kept in a dark place at all times, the storage temperature should not exceed 35℃, and direct sunlight should be avoided.
②It may freeze when the temperature is below 0℃, so anti-freezing measures should be taken.
③The composite series of membrane elements should be immersed in pure water or reverse osmosis filtered water containing stored chemicals (sodium bisulfite, 500-1000mg/L, pH 3-6).
④ When storing under any circumstances, the membrane should not be kept in a dry state.
⑤ The concentration and pH of the preservation solution must be kept within the above range, and regular inspections are required. If it may deviate from the above range, prepare the preservation solution again.
