A common challenge with RO membrane elements is the occurrence of fouling. Fouling may not alter the structure of RO membrane elements, but the accumulation of foulants on the membrane surface can dramatically degrade its performance.
Proshare Anti-Fouling reverse osmosis (RO) has the capability to prevent fouling through a unique hydrophilic coating applied to the membrane surface, ensuring long-term stable operations. This innovative approach to preventing fouling minimizes cleaning frequency, thereby significantly contributing to lower Operational Expenditure (OPEX) at water treatment facilities.
Proshare Anti- Fouling is precisely tailored to meet your needs for treating urban sewage water in industrial applications.

Farming applications
Water plays a vital role in ensuring the optimal health and performance of farm animals such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water significantly impact the growth and productivity of these animals.
Farm water resources can originate from diverse sources like water wells, municipal water networks, and, to a lesser extent, from rivers and surface sources.
Apart from water from municipal networks (which contain free chlorine), other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most efficient method to mitigate these adverse effects, ensuring contaminated water undergoes essential technological treatment to eliminate substances detrimental to animal health.

Proshare Team's Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes leveraging polymer interface nano-self-assembly technology. This innovation triumphantly transcends the traditional barriers in the development of reverse osmosis membranes through two pivotal breakthroughs:
Ultra-Thin Separation Layer Mastery: Harnessing the power of polymer interface nanotechnology, the team has achieved a remarkable reduction in the thickness of the separation layer, crafting it to be at least three times thinner than the conventional polyamide thin film (historically restricted to 100 nm). This revolutionary advancement dramatically bolsters water flux, thereby boosting permeability to unprecedented levels.
Advanced Performance Augmentation: With the strategic integration of nanoparticles and specialized hydrophilic polymers, we have catalyzed groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling capabilities, robustness, and resistance to oxidation.
In contrast to the traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modifications, we achieve the creation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This sophisticated approach surpasses the conventional limits of polyamide membranes in achieving uniform thickness and material diversity.
Enhanced Water Flux and Elevated Energy Efficiency
By refining the layer-by-layer self-assembly process, we meticulously manage the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This optimization leads to a remarkable >3x increase in water flux coupled with a substantial 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Venturing beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These avant-garde materials exhibit extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering Excellence
The ultra-hydrophilic surface (contact angle <10°) fortified with nanoparticle enhancement significantly decreases organic fouling potential by 50%, thereby extending chemical cleaning intervals from 3 to 6 months and cutting maintenance costs by an impressive 40%.
