A prevalent issue with RO membrane elements is fouling, which can drastically diminish their efficacy. While fouling does not alter the structural integrity of RO membrane elements, the deposits on the membrane surface can significantly impair performance.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by utilizing an innovative hydrophilic coating on the membrane surface. This advanced technology enables long-term stable operation, reducing the need for frequent cleanings and thereby decreasing operational expenses (OPEX) in water treatment facilities.
Proshare Anti- Fouling perfectly addresses your requirements for treating urban sewage water, tailored for industrial applications.

Proshare Team's Revolutionary Advancement in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our brilliant team has ingeniously crafted a new era of reverse osmosis membranes leveraging cutting-edge polymer interface nano-self-assembly technology. This remarkable innovation pushes past the boundaries of traditional membrane development with two transformative advancements:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our experts have impressively refined the separation layer's thickness to a striking three-fold reduction compared to conventional polyamide thin films (originally capped at 100 nm). This pioneering advancement significantly amplifies water flux, driving a remarkable leap in permeability.
Enhanced Performance: The strategic introduction of nanoparticles alongside specialized hydrophilic polymers has ushered in groundbreaking progress in the membrane's hydrophilicity, robust anti-fouling capabilities, exceptional durability, and impressive oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's breakthrough reveals innovations across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through precision nano-scale control and advanced nano-doping modification, ultra-thin, highly ordered separation layers are masterfully created using polymer interface nanotechnology. This methodology triumphs over traditional polyamide membranes' challenges in uniform thickness and material versatility.
Enhanced Water Flux and Energy Efficiency
By meticulously fine-tuning the layer-by-layer self-assembly process, the functional layer's thickness is expertly managed, resulting in a substantial 3x reduction compared to traditional membranes. This advancement delivers a remarkable >3x increase in water flux while ensuring a notable 30% reduction in energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
By surpassing polyamide, the team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which showcase extraordinary resistance to oxidation (withstanding exposure to 10 ppm chlorine) and impressive pH resilience (maintaining stability in the pH range of 1 to 12).
