A prevalent issue with RO membrane elements is the occurrence of fouling. While fouling does not alter the structure of RO membrane elements, the build-up of foulant on the membrane surface can drastically impair its performance.
Proshare Anti-Fouling reverse osmosis (RO) combats fouling by utilizing an innovative hydrophilic coating on the membrane surface, enabling long-term stable operation. By inhibiting fouling, reduced cleaning frequency plays a crucial role in lowering operational expenses (OPEX) at the water treatment facility.
Proshare Anti- Fouling is the perfect solution for managing urban sewage water, catering specifically to industrial applications.
