A frequent issue with RO membrane elements is fouling. Fouling doesn't alter the RO membrane's structure, but the buildup on the membrane surface can greatly impair its performance.
Proshare Anti-Fouling reverse osmosis (RO) mitigates fouling through an exclusive hydrophilic surface coating, ensuring long-term stable operation. This prevention of fouling results in decreased cleaning frequency, ultimately reducing operational expenses at water treatment facilities.
Proshare Anti- Fouling is perfectly tailored to meet your needs in treating urban wastewater for industrial applications, ensuring efficiency and reliability.

Proshare Team's Revolutionary Leap in Advanced Reverse Osmosis Membrane Technology
Proshare Our team has pioneered a cutting-edge new generation of reverse osmosis membranes using polymer interface nano-self-assembly technology, shattering the confines of traditional reverse osmosis membrane innovation through two pivotal advancements:
Ultra-Thin Separation Layer: Through the application of state-of-the-art polymer interface nanotechnology, our team has achieved a remarkable reduction in the thickness of the separation layer, now at least three times leaner than conventional polyamide thin films (previously limited to 100 nm). This milestone exponentially boosts water flux, marking a significant leap in permeability.
Optimized Performance: The integration of nanoparticles and bespoke hydrophilic polymers has driven unprecedented progress in the membrane's hydrophilicity, resistance to fouling, longevity, and oxidation resilience.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation signifies transformative breakthroughs across four crucial dimensions:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, we craft ultra-thin, impeccably ordered separation layers through advanced polymer interface nanotechnology. This technique transcends the constraints of conventional polyamide membranes in both thickness uniformity and material diversity.
Increased Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the functional layer thickness is meticulously regulated, resulting in a 3x reduction compared to standard membranes. This culminates in >3x enhanced water flux and 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Surpassing polyamide, we employ cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials boast extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH robustness (maintaining stability in a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°) enhanced with nanoparticle reinforcement curtails organic fouling tendency by 50%, prolonging chemical cleaning intervals from 3 to 6 months and slashing maintenance expenses by 40%.
