Why is pretreatment necessary before using the membrane?

Pretreatment is needed because high concentration organic solvents or unqualified wastewater can destroy the membrane surface, block pores, and reduce water flux.

Where is the factory located?

The factory is located at No.1006, Yuexiu Road, Fenhu High-Tech Development Zone, Wujiang District, Suzhou, Jiangsu, China.
