Fouling is a prevalent issue that can affect RO membrane elements. While fouling does not alter the RO membrane's structure, the accumulation of foulants on its surface can significantly hamper performance.
Proshare Anti-Fouling reverse osmosis (RO) proactively combats fouling through a patented hydrophilic coating on the membrane surface, ensuring consistent and reliable long-term operation. By minimizing fouling, the frequency of cleaning is reduced, leading to lower operational expenses (OPEX) in water treatment facilities.
Proshare Anti- Fouling solutions perfectly meet your needs for treating urban sewage water in industrial applications.

Water is indispensable in ensuring optimal animal health (e.g., cattle, chickens, sheep, pigs) and achieving superior productivity. Both the quantity and quality of water are crucial to the desired growth and performance of livestock.
Farms source water from various origins such as wells, civil water networks, and occasionally from rivers and surface sources.
Excluding civil network water (which contains free chlorine), other sources often present high levels of dissolved/suspended solids and pathogens. Reverse osmosis technology has emerged as the most effective method to mitigate the adverse effects of contaminants in farm water, necessitating advanced technological treatment to safeguard animal health.

Proshare Revolutionizing Reverse Osmosis with Cutting-Edge Technology
Proshare Our visionary team has pioneered a groundbreaking new generation of reverse osmosis membranes, leveraging the sophisticated prowess of polymer interface nano-self-assembly technology. This breakthrough triumphantly surpasses the constraints of traditional reverse osmosis membranes with two monumental advancements:
Ultra-Thin Separation Layer: With the innovative use of polymer interface nanotechnology, our team has remarkably thinned the separation layer to a mere fraction-three times thinner than the conventional polyamide thin film (historically constrained to a 100 nm limit). This landmark achievement dramatically boosts water flux, delivering a significant leap in permeability.
Enhanced Performance: Through the strategic incorporation of nanoparticles and state-of-the-art hydrophilic polymers, we have realized unparalleled strides in enhancing the membrane's hydrophilicity, anti-fouling strength, robustness, and resistance to oxidation.
When compared to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation boasts substantial breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By marrying nano-scale precision control with nano-doping modification, we deftly engineer ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This methodology breaks the barriers of conventional polyamide membranes, enhancing both thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our mastery of the layer-by-layer self-assembly process allows us to precisely control the functional layer thickness, slashing it by a factor of three compared to traditional membranes. This innovation leads to >3x the water flux while reducing energy consumption by 30%.
Novel Polymer Materials with Unmatched Chemical Stability
Surpassing the limitations of polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These advanced materials showcase extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and exceptional pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Mastery
Our ultra-hydrophilic surface (boasting a contact angle of <10°) fortified with nanoparticle reinforcement dramatically diminishes organic fouling by 50%. This innovation extends chemical cleaning intervals from three to six months while slashing maintenance costs by 40%.
Our commitment to excellence is underscored by our prestigious certifications, including the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the acclaimed ISO9001 Quality System Certificate.
