A prevalent issue with RO membrane elements is fouling. While fouling doesn't alter the structure of RO membrane elements, the buildup of fouling agents on the membrane's surface can severely diminish its performance.
Proshare's Anti-Fouling reverse osmosis (RO) successfully mitigates fouling by utilizing a proprietary hydrophilic coating on the membrane surface, ensuring long-term stable operations. This fouling prevention strategy reduces cleaning frequency, contributing to lower operational expenditures (OPEX) at water treatment facilities.
Proshare's Anti- Fouling membrane meets your needs for treating urban sewage water for industrial applications with excellence.

Proshare's extensive experience in desalination technology is harnessed for civil water needs in hotels and tourist resorts. Our R.O. desalination solutions for seawater and brackish water are the perfect response to the increasing water demand in burgeoning tourist areas, ensuring a steady supply of fresh water to support rapid expansion.
Farming applications
Water quality is vital to guarantee the optimal health and productivity of farm animals such as cattle, chickens, sheep, and pigs. The quality, as well as quantity, of water can significantly influence growth and performance outcomes.
The water utilized on farms originates from multiple sources such as water wells, civil water networks, and occasionally rivers and other surface sources.
Apart from civil networks, which contain free chlorine, other water sources typically harbor high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has been proven to effectively minimize these detriments. Farm water, therefore, necessitates sophisticated treatment to mitigate harmful substances, safeguarding animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare Innovation Suzhou Co., Ltd. has ingeniously crafted a state-of-the-art generation of reverse osmosis membranes, leveraging the cutting-edge polymer interface nano-self-assembly technology. We have transcended the barriers of conventional reverse osmosis membrane development through two pivotal breakthroughs:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has remarkably minimized the thickness of the separation layer, making it at least three times thinner than the customary polyamide thin films, which were previously constrained to a 100 nm thickness. This innovation markedly enhances water flux, leading to a significant boost in permeability.
Enhanced Performance: By infusing nanoparticles and specialized hydrophilic polymers, we have pioneered unprecedented advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's trailblazing innovation unveils breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
Through the seamless integration of nanoscale precision control and nano-doping modification, we have engineered ultra-thin and highly ordered separation layers via polymer interface nanotechnology. This strategy surmounts the challenges of conventional polyamide membranes, ensuring thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving a dramatic 3x reduction compared to traditional membranes. This meticulous engineering culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond the limitations of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and remarkable pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
With an ultra-hydrophilic surface (contact angle <10°) and nanoparticle reinforcement, we have effectively reduced the tendency for organic fouling by 50%. This innovation extends the duration between chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by 40%.
