A persistent challenge with RO membrane elements is the issue of fouling, which can be a significant concern. While fouling doesn't alter the fundamental structure of RO membranes, the deposition on the surface can markedly diminish performance efficiency.
Proshare Anti-Fouling reverse osmosis (RO) defends against fouling with a unique and proprietary hydrophilic coating on the membrane, ensuring prolonged and stable performance. By minimizing fouling, frequent cleanings are reduced, leading to substantial savings in operational expenses (OPEX) for water treatment facilities.
The Proshare Anti- Fouling solution is ideal for efficiently treating urban sewage for industrial applications, meeting high demands with ease.

Farming applications
Water plays a critical role in ensuring the optimum health and productivity of farm animals such as cattle, chickens, sheep, and pigs. While water quantity is important, the quality of water is equally crucial in influencing the desired growth and performance of these animals.
Farm water supply sources are diverse, originating from water wells, civil water networks, and occasionally from rivers and other surface sources. Each source presents unique characteristics essential for consideration.
Apart from civil networks (which contain free chlorine), other water sources often exhibit high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology proves to be a highly effective method to mitigate negative impacts, treating contaminated farm water to remove harmful substances and ensuring animal well-being.

Proshare Pioneering Team's Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has successfully crafted a new generation of reverse osmosis membranes utilizing advanced polymer interface nano-self-assembly technology. This revolutionary approach surpasses the limitations faced by traditional reverse osmosis membrane development through two remarkable advancements:
Revolutionary Ultra-Thin Separation Layer: Through the ingenious use of polymer interface nanotechnology, our team has achieved an incredible reduction in the separation layer's thickness, rendering it at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This momentous breakthrough leads to a dramatic enhancement in water flux, substantially elevating permeability.
Superior Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, Proshare has achieved remarkable advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
When compared to the traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation shines through remarkable breakthroughs in four fundamental aspects:
Self-Assembled Nanocomposite Films at Their Best
Employing nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This strategy overcomes the challenges of conventional polyamide membranes concerning thickness uniformity and material diversity.
Elevated Water Flux and Unmatched Energy Efficiency
Thanks to the optimized layer-by-layer self-assembly process, we precisely control the functional layer's thickness, resulting in a remarkable threefold reduction compared to traditional membranes. This leads to over 3 times higher water flux and a remarkable 30% reduction in energy consumption.
Introduction of Novel Polymer Materials with Unparalleled Chemical Stability
Our advancement beyond polyamide involves the use of leading-edge hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials boast remarkable oxidation resistance (enduring exposure to 10 ppm chlorine) and outstanding pH tolerance (maintaining stability within a 1-12 pH range).
Revolutionary Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle of less than 10°) reinforced by nanoparticles significantly diminishes organic fouling propensity by a margin of 50%, extending chemical cleaning cycles from three months to six months, and reducing maintenance costs by an impressive 40%.
Our dedication to the highest standards is showcased through our comprehensive certifications.
