A prevalent issue with RO membrane elements is fouling, a challenge we adeptly address. While fouling does not alter the structural integrity of RO membrane elements, the presence of foulants on the membrane surface can significantly impede their performance efficiency.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling by implementing a proprietary hydrophilic coating on the membrane surface. This strategic enhancement facilitates long-term stable operation. By proactively preventing fouling, it substantially reduces the frequency of cleanings, ultimately leading to a noticeable decrease in OPEX at the water treatment facility, benefiting the bottom line.
Proshare Anti- Fouling is the ideal solution for your requirements in treating urban sewage water tailored for industrial applications.

Farming applications
Water is crucial to ensure the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. The quality, not just the quantity of water, plays a significant role in optimizing animal growth and performance.
Farm water sources vary, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding civil network water, which contains free chlorine, other sources often have high levels of dissolved and suspended solids and pathogens. Hence, reverse osmosis technology proves highly effective in mitigating these negative impacts, treating contaminated farm water to reduce harmful substances for animals.

Proshare - Pioneering Excellence The Team's Revolutionary Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare - Leading Innovation Our pioneering team at Proshare has masterfully crafted a new era of reverse osmosis membranes leveraging advanced polymer interface nano-self-assembly technology. This innovation triumphs over the traditional constraints of reverse osmosis membrane development by spearheading two monumental advancements:
Ultra-Thin Separation Layer - A Leap Ahead: Utilizing state-of-the-art polymer interface nanotechnology, our team has ingeniously minimized the separation layer's thickness to a mere fraction of its former dimensions, making it at least three times thinner than the conventional polyamide thin film (which was capped at 100 nm). This groundbreaking achievement significantly boosts water flux, thereby offering a remarkable enhancement in permeability.
Enhanced Performance - A New Standard: Thanks to the infusion of nanoparticles and specially engineered hydrophilic polymers, we have unveiled groundbreaking improvements in our membrane's hydrophilicity, anti-fouling properties, endurance, and oxidation resilience.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovative strides illuminate breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films - Precision Redefined
By seamlessly integrating nano-scale precision control with nano-doping modifications, we create ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovation transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material variety.
Enhanced Water Flux and Superior Energy Efficiency
Through the refinement of the layer-by-layer self-assembly process, we precisely manage the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This advancement culminates in >3x higher water flux, coupled with a 30% reduction in energy consumption.
Novel Polymer Materials Boasting Unrivaled Chemical Stability
Surpassing the constraints of polyamide, our team employs advanced hydrophilic polymers (like modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials boast exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering - Redefining Clean
Our ultra-hydrophilic surface (boasting a contact angle of <10°) enhanced with nanoparticle reinforcement, diminishes organic fouling inclination by 50%, effectively doubling chemical cleaning intervals from 3 to 6 months and slashing maintenance expenses by 40%.
