One of the typical challenges with RO membrane elements is fouling. While fouling doesn't alter the inherent structure of RO membrane elements, the accumulation of deposits on the surface can considerably impair their performance.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by utilizing an exclusive hydrophilic coating on the membrane surface. This innovation promotes prolonged, stable operations by mitigating fouling, ultimately reducing cleaning frequency and lowering the overall operational expenses (OPEX) in water treatment facilities.
Proshare Anti- Fouling is the perfect solution for processing urban sewage water tailored for industrial application needs.

Proshare: A Leader in Innovation Team's Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare: Innovating for the Future Our talented team has ingeniously crafted an advanced generation of reverse osmosis membranes leveraging polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional membrane methodologies, thanks to two pivotal breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Through the application of state-of-the-art polymer interface nanotechnology, the team has successfully achieved a remarkable reduction in the thickness of the separation layer, making it at least three times thinner than the conventional polyamide thin film, which was previously limited to 100 nm. This significant advancement elevates water flux, delivering a profound enhancement in permeability.
Unprecedented Enhanced Performance: The strategic incorporation of nanoparticles and tailored hydrophilic polymers has catalyzed extraordinary improvements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare'sinnovative technology showcases remarkable breakthroughs in four critical areas:
Advanced Self-Assembled Nanocomposite Films
