A common challenge with RO membrane elements is fouling, which can impede efficiency. While fouling doesn't alter the intrinsic structure of RO membrane elements, the accumulation of foulants on the membrane surface can drastically diminish its operational performance.
Proshare Anti-Fouling reverse osmosis (RO) combats fouling effectively by utilizing an exclusive hydrophilic coating on the membrane surface. This innovation ensures prolonged stable operation. By mitigating fouling, it reduces cleaning frequency, ultimately contributing to lower operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling fulfills your requirements for treating urban sewage water, optimized for industrial applications.

Farming applications
Water quality is paramount in ensuring the well-being and optimal performance of livestock, such as cattle, chickens, sheep, and pigs. While the quantity of water is crucial for desired growth, its quality is equally vital to animal health.
Farm water sources are diverse, comprising water wells, civil water networks, and occasionally rivers or other superficial sources. Each source requires careful management to maintain water quality.
Non-civil water sources often contain high levels of dissolved and suspended solids along with pathogens. Reverse osmosis technology is proven to be the most effective method to counter these adverse effects, necessitating technological treatment of farm water to minimize harmful substances that could affect animal health.

Proshare Unveiling the Team's Revolutionary Leap in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our visionary team at Proshare has ingeniously crafted a next-gen reverse osmosis membrane harnessing groundbreaking polymer interface nano-self-assembly technology. This pioneering development triumphs over traditional membrane constraints through two groundbreaking innovations:
Revolutionary Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has impressively minimized the separation layer's thickness to a remarkable one-third of the conventional polyamide thin film (previously limited to 100 nm). This monumental advancement dramatically amplifies water flux, ushering in a new era of permeability.
Unparalleled Performance Enhancement: By integrating nanoparticles and specialized hydrophilic polymers, we've achieved transformative advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and unparalleled oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's innovation represents a quantum leap forward in four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have mastered the ability to craft ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This state-of-the-art approach transcends the limitations of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux Coupled with Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving an astounding 3x reduction compared to traditional membranes. This breakthrough culminates in over 3x higher water flux and a striking 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Exceptional Chemical Stability
Advancing beyond polyamide, our team employs avant-garde hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials exhibit extraordinary oxidation resistance (capable of withstanding up to 10 ppm chlorine exposure) and pH resilience (maintaining stability within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (boasting a contact angle of less than 10°) combined with nanoparticle reinforcement minimizes organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to an exceptional 6 months, while simultaneously slashing maintenance costs by a substantial 40%.
