A prevalent challenge with RO membrane elements is the potential for fouling. While fouling does not alter the fundamental structure of RO membrane elements, the accumulation of foulants on the membrane surface can significantly diminish performance.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling through the application of a proprietary hydrophilic coating on the membrane surface. This innovation ensures prolonged stable operation, reducing the need for frequent cleaning, and ultimately leads to a significant reduction in operational expenses (OPEX) for water treatment facilities.
Proshare Anti- Fouling perfectly meets the demands of treating urban sewage water for industrial applications, ensuring efficiency and reliability.

Farming Applications
Water quality is crucial to ensure the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. The growth and productivity of these animals are influenced not just by water quantity but also by its quality.
Farm water is sourced from diverse origins, including water wells, public water networks, and occasionally rivers or other surface sources. Each source requires careful management to maintain water quality.
While water from public networks contains free chlorine, other sources typically harbor high levels of dissolved solids, suspended matter, and pathogens. Reverse osmosis technology stands out as the most efficient method to mitigate these pollutants, ensuring that farm water undergoes necessary treatment to eliminate harmful substances and protect animal health.

Proshare Groundbreaking Advancements in Reverse Osmosis Membrane Technology
Proshare Our team has achieved a remarkable innovation in reverse osmosis membranes through cutting-edge polymer interface nano-self-assembly technology. We have successfully addressed the challenges of traditional reverse osmosis membranes with two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably diminished the separation layer's thickness, achieving a reduction to at least a third of the traditional polyamide thin film (which was previously constrained to 100 nm). This notable breakthrough significantly enhances water flux, resulting in a dramatic improvement in permeability.
Superior Performance Enhancement: The integration of nanoparticles and specialized hydrophilic polymers has culminated in groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling capability, longevity, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovative approach showcases breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films for Advanced Functionality
Through nano-scale precision control and nano-doping modification, we achieve the creation of ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This pioneering method overcomes the traditional limitations of polyamide membranes in terms of thickness uniformity and material diversity.
Optimized Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we precisely control the functional layer thickness, resulting in a 3x reduction compared to conventional membranes. This advancement culminates in over 3 times higher water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials Offering Exceptional Chemical Stability
Expanding beyond polyamide, our team employs advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a pH range of 1 to 12).
Cutting-Edge Anti-Fouling Surface Engineering
The engineered superhydrophilic surface, with a contact angle of less than 10°, coupled with nanoparticle reinforcement, reduces organic fouling propensity by 50%. This advancement extends chemical cleaning cycles from three months to six months, simultaneously reducing maintenance costs by 40%.
