A prevalent issue with RO membrane elements is fouling. While fouling doesn't alter the intrinsic structure of RO membrane elements, it can greatly impair performance due to deposits on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) combats fouling through the application of a unique hydrophilic coating on the membrane's surface. This innovative approach ensures stable, long-term operation. By minimizing fouling, the frequency of cleaning is reduced, ultimately leading to lower operational expenses (OPEX) at the water treatment facility.
Proshare Anti- Fouling is the perfect solution for addressing the challenges of treating urban sewage water for industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has achieved a revolutionary leap forward with the development of a state-of-the-art reverse osmosis membrane. Leveraging the cutting-edge polymer interface nano-self-assembly technology, we've shattered the constraints of traditional membrane development with two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, Proshare has successfully crafted a separation layer that is at least three times thinner than the conventional polyamide thin films, which were previously restricted to a 100 nm thickness. This remarkable achievement greatly enhances water flux, making a substantial leap in permeability possible.
Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, Proshare has unlocked unprecedented advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting a new standard in membrane technology.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation reveals breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification has enabled the creation of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This advancement transcends the limitations of conventional 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, the thickness of the functional layer is meticulously controlled, achieving a threefold reduction compared to standard membranes. This meticulous engineering results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our experts utilize advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These innovative materials exhibit exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, reduces the tendency for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to an impressive 6 months, significantly reducing maintenance costs by 40%.
