Protective fluid residueThe new RO film contains protective liquid before leaving the factory. The first operation needs to open the water production discharge valve and rinse for 30 to 60 minutes. After the protective liquid is thoroughly rinsed, the TDS value will return to normal.
Membrane element installation in place problem: Check whether the RO membrane sealing ring is damaged or not installed in place, resulting in a "short circuit" of the raw water directly entering the production pipe without filtration.
pretreatment failureCheck whether the pre-media filter, softening water or scale inhibitor dosing system is running normally, and the influent SDI (pollution index) or hardness exceeding the standard will directly affect the desalination rate of the RO film.
