A frequent issue with RO membrane elements is fouling. While fouling does not alter the RO membrane element's structure, the buildup of foulants on the membrane surface can drastically diminish its performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) utilizes a proprietary hydrophilic coating on the membrane surface, ensuring prolonged and stable operation. By preventing fouling, the reduced cleaning frequency ultimately results in lower OPEX at the water treatment plant.
Proshare Extreme Anti- Fouling perfectly fits your needs for treating urban sewage water tailored for industrial applications.

Farming applications
Water quality is crucial in ensuring the well-being and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. It's not just the quantity but also the quality of water that matters.
Farm water can originate from various sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water from civil networks containing free chlorine, other sources often contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven most effective in mitigating these negative effects. Contaminated farm water should undergo technological treatment to remove harmful substances, ensuring the health and productivity of the animals.
Proshare PSI MEMBRANE Desalination RO Membrane Caters to Desalination Needs in Luxury Cruise Ships
The utilization of desalination membranes aboard prestigious international luxury cruise ships has, for a significant period, been under the control of leading global brands.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our talented team at Proshare has ingeniously crafted a groundbreaking new generation of reverse osmosis membranes harnessing cutting-edge polymer interface nano-self-assembly technology. This revolutionary approach addresses and surpasses the traditional challenges of reverse osmosis membrane development through two pioneering advancements:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has successfully revolutionized the separation layer, achieving an impressive reduction in thickness-making it at least three times thinner than the conventional polyamide thin film, which was traditionally limited to 100 nm. This remarkable breakthrough enhances water flux, significantly boosting permeability.
Enhanced Performance: By infusing nanoparticles and utilizing specialized hydrophilic polymers, we have unleashed groundbreaking enhancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
The meticulous integration of nano-scale precision control with nano-doping modification allows the formation of ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This innovative strategy not only overcomes the conventional polyamide membranes' constraints in thickness uniformity but also expands material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we precisely manage the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. The outcome is >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Evolving beyond conventional polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These extraordinary materials exhibit unmatched oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
With a superhydrophilic surface boasting a contact angle of less than 10°, paired with nanoparticle reinforcement, we achieve a 50% reduction in organic fouling propensity. This advancement extends chemical cleaning cycles from 3 months to 6 months while slashing maintenance costs by 40%.
