FAQ
1. Dry or Wet type, which is better?
Dry membrane normally understands as easy-keeping.
Wet type mainly understands as quality and performance guaranteed.
Based on nowadays quality control, most of people choose dry type.
2. Wet membrane protection liquid knowledge?
Wet membrane components are strictly tested before leaving the fatory, and 1.0% sodium bisulfite (in winter, 10% glycerol antifreeze is added) solution for storage treatment, and then vacuum packaging, outer packaging for cardboard boxes. To prevent microbial growth during short-term storage, transportation, and system standby, it is recommended to soak components with a protective solution (prepared with RO production water) containing 1.0% sodium bisulfite (food grade).
The water produced in the first hour of operation should be discharged.
In the storage and operation, it is prohibited to add any chemical agent that has an impact on the membrane element. If such chemical agent is used in violation, Hangzhou Puri-guard will not bear all the consequences arising therefrom.

a. When pH >10, the maximum allowable temperature for continuous operation is 95℉(35℃).
b. Under certain conditions, the presence of free chlorine and other oxidants will lead to premature failure of membranes. Therefore, it is recommended that the membrane be pretreated to remove residual free chlorine before water comes into contact with membranes.
