A prevalent issue with RO membrane elements is fouling, which can impact operational efficiency. Fouling does not alter the inherent structure of RO membrane elements, yet the accumulation of foulants on the membrane surface can markedly decrease performance.
Proshare Anti-Fouling reverse osmosis (RO) technology effectively combats fouling through the application of a proprietary hydrophilic coating on the membrane surface, ensuring prolonged and stable operations. By mitigating fouling, the system reduces the frequency of cleaning, ultimately leading to decreased operational expenditure (OPEX) in water treatment facilities.
Proshare Anti- Fouling is the ideal choice for processing urban sewage water tailored for industrial applications.

Farming applications
Water quality is crucial in ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. While the volume of water is important, its quality plays a pivotal role in promoting desired animal growth.
Farm water sources can include water wells, municipal water networks, and, to a lesser extent, rivers and other surface sources. While municipal water may contain free chlorine, other sources often harbor high levels of dissolved solids, suspended particles, and pathogens.
Reverse osmosis technology has proven to be the most effective means of mitigating the adverse impacts of contaminants found in farm water. It is imperative that farm water undergoes technological treatment to diminish substances potentially harmful to animal health.

Proshare Unleashing Innovation: Pioneering Advancements in Next-Gen Reverse Osmosis Membrane Technology
Proshare has revolutionarily crafted a cutting-edge series of reverse osmosis membranes through groundbreaking polymer interface nano-self-assembly technology, transcending traditional developmental constraints with two pivotal innovations:
Revolutionary Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has ingeniously refined the separation layer's thickness to be at least three times thinner than conventional polyamide thin films (formerly restricted to 100 nm). This monumental stride dramatically elevates water flux, marking a remarkable boost in permeability.
Enhanced Membrane Performance: By integrating cutting-edge nanoparticles and uniquely tailored hydrophilic polymers, Proshare has achieved unprecedented leaps in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative advancements across four critical dimensions:
Self-Assembled Nanocomposite Films: A Paradigm Shift
Harnessing nano-scale precision control and nano-doping modification, Proshare engineers ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This novel technique overcomes the traditional polyamide membrane limitations in thickness uniformity and material diversity.
Optimized Water Flux and Energy Efficiency
Through the refined layer-by-layer self-assembly process, we achieve exact control over functional layer thickness, attaining a 3x reduction compared to conventional membranes. This exceptional precision results in >3x the water flux paired with 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Surpassing the boundaries of polyamide, our team employs avant-garde hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials exhibit extraordinary resistance to oxidation (withstanding chlorine exposure up to 10 ppm) and tolerance to pH variations (maintaining stability across a pH range of 1-12).
Pioneering Anti-Fouling Surface Engineering
