A prevalent issue with RO membrane elements is fouling. While fouling does not alter the RO membrane's structure, the accumulation on its surface can drastically diminish performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) effectively combats fouling by employing a pioneering hydrophilic coating on the membrane surface, ensuring long-term stable operation. This fouling prevention reduces cleaning frequency, contributing to significantly lower OPEX at water treatment facilities.
Proshare Extreme Anti- Fouling is tailored to meet the demands of treating urban sewage water for industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has redefined the benchmarks of reverse osmosis membranes by employing cutting-edge polymer interface nano-self-assembly technology. Through our tireless dedication, we have transcended the constraints of traditional development, achieving transformative improvements in two pivotal areas:
Ultra-Thin Separation LayerUtilizing advanced polymer interface nanotechnology, our team has successfully achieved an astonishing reduction in the separation layer's thickness to a remarkable degree-making it a minimum of three times thinner than the conventional 100 nm polyamide thin film. This groundbreaking advancement exponentially boosts water permeability and significantly elevates water flux.
Enhanced PerformanceWith the strategic inclusion of nanoparticles and cutting-edge hydrophilic polymers, we have radically enhanced the membrane's hydrophilicity, fortified its anti-fouling capabilities, and substantially improved both its durability and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas achieved remarkable breakthroughs in four crucial domains:
Self-Assembled Nanocomposite Films
Harnessing nano-scale precision control alongside nano-doping modifications, we craft ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This sophisticated method triumphs over traditional polyamide membrane limitations concerning thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we expertly regulate the functional layer's thickness, achieving a remarkable threefold reduction compared to conventional membranes. This innovation culminates in an impressive >3x increase in water flux and an outstanding 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
In a significant departure from traditional polyamide solutions, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These forward-thinking materials demonstrate remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and superb pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, boasting a contact angle of less than 10°, combined with robust nanoparticle reinforcement, effectively diminishes organic fouling by an impressive 50%. This breakthrough extends chemical cleaning cycles from 3 months to 6 months, while slashing maintenance costs by 40%.
