A prevalent issue with RO membrane elements is fouling, which our solution addresses comprehensively. While fouling does not alter the structural integrity of RO membrane elements, the presence of foulants on the membrane surface can drastically impair its operational efficiency.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling through the application of a patented hydrophilic coating on the membrane surface. This innovation ensures long-term stable operation. By minimizing fouling, the frequency of cleaning is reduced, which in turn lowers the operational expenditure (OPEX) in water treatment facilities.
Proshare Anti- Fouling is the perfect solution for your needs in treating urban sewage water for industrial applications, offering both efficiency and reliability.
