One prevalent issue with RO membrane elements is fouling, which can severely impact their efficiency. While fouling does not alter the structural integrity of RO membrane elements, the accumulation of foulant on the membrane surface can drastically diminish performance.
Proshare Anti-Fouling reverse osmosis (RO) hinders fouling by deploying a unique hydrophilic coating on the membrane surface, facilitating long-term stable operation. This anti-fouling feature reduces the cleaning frequency, thereby significantly lowering operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling is perfectly tailored to meet the demands of urban sewage water treatment for industrial applications, providing unmatched efficacy and reliability.

Proshare Revolutionary Team Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our forward-thinking team has ingeniously pioneered a new generation of reverse osmosis membranes, leveraging the groundbreaking polymer interface nano-self-assembly technology. This innovation triumphantly breaks through the traditional barriers in reverse osmosis membrane development by achieving two monumental advancements:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has adeptly minimized the separation layer's thickness to achieve an incredible threefold reduction compared to the conventional polyamide thin films, which were previously constrained to 100 nm. This revolutionary reduction vastly elevates water flux, leading to remarkable gains in permeability.
Enhanced Performance: The incorporation of cutting-edge nanoparticles and unique hydrophilic polymers ushers in transformative enhancements in the membrane's hydrophilicity, anti-fouling prowess, durability, and formidable oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovative strides reveal breakthroughs in four pivotal dimensions:
