A prevalent challenge with RO membrane elements is fouling, which can hinder the efficiency of the system. Although fouling does not alter the core structure of RO membrane elements, the presence of foulants on the membrane surface can markedly diminish its operational efficacy.
Proshare's Anti-Fouling Reverse Osmosis (RO) system combats fouling proactively by utilizing a unique hydrophilic coating on the membrane surface. This innovation ensures enduring stability, minimizing cleaning requirements and subsequently lowering operational expenditure (OPEX) in water treatment facilities.
Proshare's Anti- Fouling solution is perfectly tailored to meet the demands of treating urban sewage water for industrial applications, offering a robust and efficient solution.

Farming applications
Water quality is crucial for farm animal health and achieving optimal productivity in livestock such as cattle, chickens, sheep, and pigs. Not only the quantity but the purity of water significantly impacts the growth and well-being of animals.
Farm water may originate from diverse sources including wells, municipal networks, and to a lesser extent, rivers and surface sources.
While municipal water typically contains free chlorine, other sources often have high levels of dissolved solids and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these contaminants, ensuring farm water undergoes treatment to remove harmful substances that could affect animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has pioneered an innovative leap forward in reverse osmosis membrane technology. Utilizing cutting-edge polymer interface nano-self-assembly techniques, the team has transcended the limitations of traditional methods with two revolutionary advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, the team has achieved a remarkable reduction in the thickness of the separation layer-now at least three times thinner than the conventional polyamide thin film (previously restricted to 100 nm). This breakthrough significantly amplifies water flow, resulting in a dramatic enhancement in permeability.
Enhanced Performance: The infusion of nanoparticles and specialized hydrophilic polymers has ushered in groundbreaking improvements in the membrane's hydrophilicity, robust anti-fouling capabilities, enduring durability, and exceptional oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping innovation allows for the crafting of ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This approach surmounts the limitations of conventional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
With precise mastery over the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, achieving a remarkable 3x reduction compared to standard membranes. The outcome is >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the realm of polyamide, the team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These advanced materials exhibit phenomenal oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) combined with nanoparticle fortification reduces organic fouling propensity by 50%, extending chemical cleaning intervals from 3 months to 6 months while slashing maintenance costs by 40%.
