A prevalent challenge with RO membrane elements is fouling, impacting operational efficiency. While fouling does not alter the structural integrity of RO membrane elements, the accumulation of foulants on the membrane surface can significantly hinder its performance.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling through the application of a proprietary hydrophilic coating on the membrane surface, ensuring prolonged and stable operation. This anti-fouling protection reduces the frequency of cleaning interventions, thereby significantly lowering operational expenditures (OPEX) at water treatment facilities.
Proshare Anti- Fouling is meticulously designed to meet your requirements for treating urban sewage water for industrial applications, ensuring efficiency and reliability.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has achieved an innovative leap forward by developing a pioneering new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have triumphed over the confines of traditional methods through two remarkable advancements:
Ultra-Thin Separation Layer: Leveraging sophisticated polymer interface nanotechnology, our team has managed to reduce the separation layer's thickness to an astonishingly minimal level-up to three times thinner than conventional polyamide thin films, which were previously restricted to 100 nm. This significant advancement greatly boosts water flux, resulting in a dramatic enhancement in permeability.
Enhanced Performance: By integrating nanoparticles and advanced hydrophilic polymers, we have unlocked transformative improvements in the membrane's hydrophilicity, resistance to fouling, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new standards with breakthroughs in four essential areas:
Self-Assembled Nanocomposite Films
By employing nano-scale precision control and nano-doping modification, we have crafted ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This method effectively overcomes the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving an impressive threefold reduction compared to traditional membranes. This innovation delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the polyamide paradigm, we employ advanced hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These cutting-edge materials demonstrate remarkable oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability in a pH range of 1-12).
Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface with a contact angle of less than 10°, reinforced with nanoparticles, our design dramatically reduces the propensity for organic fouling by 50%. This advancement extends the interval between chemical cleanings from 3 months to 6 months, simultaneously reducing maintenance costs by 40%.
Our unwavering commitment to excellence is backed by our adherence to the highest standards of quality and safety, as evidenced by our prestigious certifications. Our portfolio includes the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the globally recognized ISO9001 Quality System Certificate.
