A prevalent challenge faced by RO membrane elements is the tendency for fouling, which can impact efficiency. While fouling does not alter the intrinsic structure of RO membrane elements, the accumulation of foulants on the membrane surface can lead to a marked reduction in performance.
Proshare Anti-Fouling reverse osmosis (RO) employs advanced technology to prevent fouling by leveraging a proprietary hydrophilic coating on the membrane surface. This innovation facilitates sustained, stable operation over time. By effectively mitigating fouling, the need for frequent cleanings is diminished, ultimately reducing operational expenses (OPEX) at water treatment facilities.
The Proshare Anti- Fouling solution is the perfect choice for efficient processing of urban sewage water tailored for industrial applications.

Farming applications
Water serves as an essential component in ensuring the health and optimal productivity of farm animals, including cattle, chickens, sheep, and pigs. Not only does the quantity of water matter, but its quality significantly impacts the desired growth performance of these animals.
Water utilized on farms may originate from various sources, including water wells, municipal water networks, and occasionally from rivers and other surface sources, each with distinct characteristics.
Excluding civil network water, which contains free chlorine, other sources often possess high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective in mitigating these adverse effects. Contaminated water on farms should undergo advanced technological treatment to reduce harmful substances, safeguarding animal health and productivity.

Proshare Team's Breakthrough in Revolutionary Reverse Osmosis Membrane Technology
Proshare The cutting-edge innovation by Proshare's team in developing a next-gen reverse osmosis membrane through polymer interface nano-self-assembly technology has shattered the conventional boundaries of traditional membrane development, marked by two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has remarkably minimized the separation layer thickness, achieving a reduction by at least threefold compared to the conventional polyamide thin film (historically capped at 100 nm). This revolutionary stride drastically amplifies water flux, paving the way for significantly enhanced permeability.
Enhanced Performance: Through the incorporation of nanoparticles and advanced hydrophilic polymers, monumental improvements in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resilience have been achieved.
Compared to existing polyamide reverse osmosis membranes, Proshare's innovation shines with breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
The synergy of nano-scale precision control with nano-doping modifications fosters the formation of ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This method transcends the traditional limitations of polyamide membranes concerning uniformity in thickness and material versatility.
Boosted Water Flux and Energy Efficiency
The layer-by-layer self-assembly process undergoes meticulous optimization, allowing precise control over the functional layer's thickness, achieving a remarkable 3x reduction compared to traditional membranes. Consequently, this leads to >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Expanding beyond the realm of polyamide, the team employs cutting-edge hydrophilic polymers (such as modified polysulfones) blended with ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface, boasting a contact angle of less than 10°, coupled with nanoparticle reinforcement, reduces the tendency for organic fouling by 50%, doubling the interval for chemical cleaning cycles from 3 months to 6 months, thereby slashing maintenance costs by 40%.
