A common challenge with RO membrane elements is fouling. While fouling does not alter the internal structure of RO membrane elements, accumulated foulants on the surface can severely impact performance.
Proshare Anti-Fouling reverse osmosis (RO) addresses fouling efficiently by applying a unique hydrophilic coating on the membrane surface, ensuring enduring stability. By mitigating fouling, it decreases the necessity for cleaning, thus contributing to reduced operational expenditures (OPEX) in water treatment plants.
Proshare Anti- Fouling is the perfect solution for those looking to treat urban sewage water for industrial applications with excellence and efficiency.
