A typical issue with RO membrane elements is fouling, which can compromise efficiency. While fouling does not alter the structural integrity of RO membrane elements, it significantly hampers performance due to the accumulation of deposits on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) technology mitigates fouling by employing a unique hydrophilic coating on the membrane surface, ensuring long-lasting stable performance. By minimizing fouling, the system reduces the need for frequent cleaning, ultimately lowering operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling is the perfect solution for treating urban sewage water, tailored for industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a groundbreaking generation of reverse osmosis membranes, leveraging the advanced polymer interface nano-self-assembly technology. This innovative approach triumphs over the constraints of conventional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness to an incredible level-three times thinner than the conventional polyamide thin film, which was previously confined to just 100 nm. This monumental innovation dramatically amplifies water flux, unlocking a significant leap in permeability.
Enhanced Performance: The strategic integration of nanoparticles and specialized hydrophilic polymers has catalyzed revolutionary advancements in our membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs in four crucial domains:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we are able to craft ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This method surpasses the limitations faced by conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, the functional layer's thickness is precision-engineered, achieving a dramatic 3x reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the realm of polyamide, our team has embraced advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These exceptional materials demonstrate remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly reduces organic fouling propensity by 50%. This advancement extends the interval between chemical cleaning cycles from 3 months to 6 months, while also reducing maintenance costs by an impressive 40%.
