A prevalent issue with RO membrane elements is fouling. Fouling does not alter the structure of RO membrane elements, yet the accumulation of foulants on the membrane surface can considerably impede their performance.
Proshare Extensive Anti-Fouling reverse osmosis (RO) effectively combats fouling by utilizing a proprietary hydrophilic coating on the membrane surface. This innovation fosters long-term stable operation. By minimizing fouling, the need for frequent cleaning is reduced, leading to a decrease in operational expenditures (OPEX) at the water treatment facility.
Proshare Extensive Anti- Fouling perfectly aligns with your needs for treating urban sewage water for industrial applications.
