A prevalent issue with RO membrane elements is fouling. While fouling doesn't alter the fundamental structure of RO membrane elements, the presence of foulants on the membrane's surface can greatly diminish its operational performance.
Proshare Anti-Fouling reverse osmosis (RO) mitigates fouling by utilizing an exclusive hydrophilic coating on the membrane surface. This innovative approach ensures sustained stable operations. By reducing fouling, the decreased cleaning frequency leads to significant OPEX reductions at water treatment facilities.
Proshare Anti- Fouling is perfectly tailored to meet your needs for treating urban sewage water, ideal for industrial applications.
