A common issue with RO membrane elements is fouling, which can impact performance. While fouling does not alter the fundamental structure of RO membranes, it can significantly impair their efficiency by accumulating on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) prevents fouling with a cutting-edge exclusive hydrophilic coating applied to the membrane surface. This innovation ensures long-term stable operation and, by minimizing fouling, reduces the frequency of cleaning. Ultimately, this leads to a decrease in operational expenditures (OPEX) at water treatment facilities.
Proshare Anti- Fouling is tailored to address the needs of treating urban sewage water for industrial applications, ensuring high performance and reliability.

Farming applications
Water is crucial for ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. Not only does the quantity of water matter for animal growth, but also its quality is essential.
Farm water can originate from diverse sources, including water wells, civil water networks, and occasionally rivers and other surface sources.
Excluding civil networks (which contain free chlorine), other water sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these negative effects. Contaminated farm water requires technological treatment to reduce harmful substances and promote animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has masterfully crafted a revolutionary line of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This breakthrough triumphantly surmounts the constraints of traditional reverse osmosis membrane development, achieved through two transformative advancements:
Ultra-Thin Separation Layer: Utilizing the power of polymer interface nanotechnology, our team has ingeniously reduced the separation layer's thickness to a fraction of its traditional counterpart-at least three times thinner than the conventional 100 nm polyamide thin film. This monumental achievement drastically enhances water flux, leading to an extraordinary boost in permeability.
Enhanced Performance: The infusion of state-of-the-art nanoparticles and bespoke hydrophilic polymers has catalyzed unprecedented advancements in the membrane's attributes, including hydrophilicity, anti-fouling prowess, durability, and heightened oxidation resistance.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation signifies unparalleled breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control coupled with nano-doping modification, we have engineered ultra-thin, exquisitely ordered separation layers through polymer interface nanotechnology. This revolutionary method transcends the constraints of traditional polyamide membranes, paving the way for superior thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the refined layer-by-layer self-assembly process, the functional layer's thickness is meticulously regulated, achieving an astounding 3x reduction compared to traditional membranes. This yields >3 times the water flux and 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond conventional polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These avant-garde materials offer remarkable oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface, characterized by a contact angle of less than 10°, combined with nanoparticle reinforcement, drastically curtails organic fouling propensity by 50%. This extends chemical cleaning cycles from 3 months to an impressive 6 months, slashing maintenance costs by a significant 40%.
