CLEANER

ENVY series of high efficiency cleaning agents contain a variety of surface active agents, chelating agents, defoamer, acid or alkaline AIDS and membrane protectants. It is suitable for the cleaning of different kinds of membrane such as RO\NF\UF. It can quickly and effectively remove the pollutants deposited on the membrane surface, but also prolong the service life of the membrane elements.
