A recurrent challenge with RO membrane elements is fouling, a critical factor in performance degradation. While fouling does not alter the fundamental structure of RO membrane elements, the deposition of foulants on the membrane surface can substantially diminish its performance efficiency.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by incorporating a unique hydrophilic coating on its membrane surface. This innovation ensures prolonged, stable operation, significantly reducing the frequency of cleaning cycles and thereby lowering the operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling fulfills your requirements for treating urban sewage water tailored for industrial applications.

Farming applications
Water quality is paramount in ensuring optimal health and productivity in farm animals such as cattle, chickens, sheep, and pigs. It is not merely the quantity but the purity of the water that influences animal growth and performance to the highest standards.
Farm water supply can originate from various sources like water wells, civil water networks, and occasionally rivers or surface sources. Each source presents unique challenges, primarily when excluding civil networks, which often contain free chlorine.
In farms, water from non-civil sources frequently harbors high concentrations of dissolved solids, suspended particles, and pathogens. Employing cutting-edge reverse osmosis technology proves to be the most effective in mitigating these detrimental elements. Contaminated water must be technologically treated to eliminate harmful substances, ensuring safe and beneficial water usage for livestock.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has ingeniously crafted a revolutionary new generation of reverse osmosis membranes. Leveraging the power of polymer interface nano-self-assembly technology, they have surmounted the traditional development constraints of reverse osmosis membranes through two monumental advancements:
Ultra-Thin Separation Layer: Through the innovative use of polymer interface nanotechnology, our team has masterfully reduced the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This unparalleled breakthrough dramatically augments water flux, achieving a remarkable enhancement in permeability.
Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, we've ushered in groundbreaking improvements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of the membrane, setting a new standard in performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's ingenious innovation showcases significant breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
By fusing nano-scale precision control with nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This groundbreaking approach transcends the conventional limitations of polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our refined optimization of the layer-by-layer self-assembly process allows for precise control of functional layer thickness, achieving a 3x reduction over traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking free from polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials are renowned for their exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
