1.The maximum temperature for continuous operation at a pH above 10 is 35°C.
2.Under certain conditions, the presence of residual chlorine and other oxidants can lead to premature membrane failure. It is recommended that users remove it through pretreatment before residual chlorine comes into contact with the membrane.
