A common issue with conventional RO membrane elements is fouling. Although fouling doesn't alter the core structure of RO membrane elements, the build-up of foulants on the membrane's surface can drastically degrade its performance.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling by utilizing an innovative hydrophilic coating applied directly to the membrane surface. This ensures long-term stable operation, reducing cleaning frequency and ultimately decreasing operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling is the perfect solution for urban sewage water treatment tailored for industrial applications.
