A common challenge with RO membrane elements is fouling, which can hamper their functionality. While fouling doesn't alter the intrinsic structure of RO membrane elements, the accumulation of foulants on the membrane surface can drastically undermine its performance.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling by utilizing a unique hydrophilic coating on the membrane surface. This innovation ensures long-term stable operation by minimizing fouling risks, thereby reducing the frequency of required cleanings and ultimately decreasing the operational expenditures (OPEX) at water treatment facilities.
Proshare Anti- Fouling is the optimal solution for meeting your urban sewage water treatment needs in industrial applications.

Farming applications
Water is paramount in guaranteeing optimal animal health and achieving superior animal productivity, be it for cattle, chickens, sheep, or pigs. It's not just the volume of water that influences growth, but the quality too.
Farm water can originate from a myriad of sources, including water wells, municipal water systems, and occasionally from rivers and other surface sources.
Excluding municipal water systems (which contain free chlorine), alternative sources tend to have high concentrations of dissolved and suspended solids and pathogens. Hence, reverse osmosis technology emerges as the leading solution, effectively treating contaminated farm water to minimize harmful substances that could adversely affect livestock.

Proshare Revolutionary Leap in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our pioneering team has ingeniously crafted a new era of reverse osmosis membranes, employing cutting-edge polymer interface nano-self-assembly technology. By surmounting the hurdles faced by traditional methods, we've introduced two groundbreaking enhancements:
Ultra-Thin Separation Layer: Harnessing advanced polymer interface nanotechnology, we've remarkably slimmed down the separation layer to a mere fraction of its traditional counterpart (previously constrained to 100 nm). This innovation catapults water flux to new heights, revolutionizing permeability with unprecedented efficiency.
Elevated Performance: Through the strategic incorporation of nanoparticles and bespoke hydrophilic polymers, we've achieved monumental strides in enhancing the membrane's hydrophilicity, anti-fouling prowess, robustness, and resistance to oxidation.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation exemplifies breakthroughs in these four vital dimensions:
Self-Assembled Nanocomposite Films
By seamlessly blending nano-scale precision control with revolutionary nano-doping modification, we craft ultra-thin, meticulously structured separation layers through polymer interface nanotechnology. This innovative method triumphs over the limitations of traditional polyamide membranes in terms of thickness consistency and material versatility.
Augmented Water Flux and Energy Efficiency
Our meticulously optimized layer-by-layer self-assembly process ensures precise control of functional layer thickness, resulting in a dramatic 3x reduction compared to conventional membranes. This advancement leads to water flux more than tripling and an impressive 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Resilience
Transitioning beyond polyamide, we leverage cutting-edge hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These materials showcase remarkable oxidation resistance (withstanding 10 ppm of chlorine exposure) and exceptional pH stability (operational within a 1-12 pH spectrum).
Innovative Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles, this design minimizes organic fouling by 50%, prolongs chemical cleaning intervals from 3 to 6 months, and reduces maintenance expenditures by an astounding 40%.
