A common challenge with RO membrane elements is fouling, which can affect performance. Fouling does not alter the RO membrane elements' structure, but the foulant on their surface can significantly diminish their efficiency.
Proshare Anti-Fouling reverse osmosis (RO) prevents fouling by utilizing an exclusive hydrophilic coating on the membrane surface, ensuring long-term stable operations. This prevention reduces cleaning frequency, ultimately lowering the operational expenses (OPEX) at a water treatment facility.
Proshare Anti- Fouling addresses your need for treating urban sewage water for industrial applications with remarkable efficiency.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our talented team at Proshare has remarkably advanced reverse osmosis membrane technology, utilizing cutting-edge polymer interface nano-self-assembly. We have overcome traditional constraints with two revolutionary advancements:
Ultra-Thin Separation Layer: By leveraging state-of-the-art polymer interface nanotechnology, we have remarkably reduced the separation layer thickness to a mere third of the conventional polyamide thin film, which was previously constrained to 100 nm. This innovation significantly boosts water flux, leading to a remarkable increase in permeability.
Enhanced Performance: Through the strategic inclusion of nanoparticles and specialized hydrophilic polymers, we have introduced transformative improvements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of the membranes.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation achieves breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the masterful integration of nano-scale precision control and nano-doping modification, our approach allows for the creation of ultra-thin, highly ordered separation layers with polymer interface nanotechnology. This method triumphs over the constraints of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we precisely manage the functional layer thickness to achieve a threefold reduction compared to conventional membranes, resulting in more than three times the water flux while consuming 30% less energy.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the limits of polyamide, we harness the potential of advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These remarkable materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface, boasting a contact angle of less than 10°, coupled with nanoparticle reinforcement, drastically reduces organic fouling tendency by 50%. This extension of chemical cleaning cycles from three to six months slashes maintenance costs by 40%.
Our unwavering commitment to excellence is validated by our prestigious certifications, which include: Health & Safety Management System Certificate, Environmental Management System Certificate, and the esteemed ISO9001 Quality System Certificate.
