A common challenge for RO membrane elements is fouling. While fouling does not alter the membrane's structure, it can greatly diminish performance by accumulating on the surface.
Proshare Anti-Fouling reverse osmosis (RO) combat fouling by employing a proprietary hydrophilic coating on the membrane surface, ensuring long-lasting stable operation. This fouling prevention results in reduced cleaning frequency, which ultimately lowers the operational expenses (OPEX) of your water treatment facilities.
Proshare Anti- Fouling is the optimal solution for treating urban sewage water for various industrial applications.

Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been controlled by a few prestigious international brands. As these ships traverse different seas, the quality of feed water varies in salinity and temperature. Thus, these membranes must adapt to fluctuating conditions while ensuring consistent and stable water production, meeting the rigorous demands of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have exhibited exceptional performance, excelling in both desalination rate and stable water output. These membranes produce water of quality that meets the stringent criteria set by luxury cruise ships.
This outstanding achievement led to the replacement of desalination membranes on three more cruise ships. Proshare's triumph in this endeavor marks it as the pioneering national brand to secure international luxury cruise ship orders concerning desalination RO membranes.

Proshare Team's Pioneering Breakthrough in Cutting-Edge Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously crafted a groundbreaking new generation of reverse osmosis membranes by harnessing the power of polymer interface nano-self-assembly technology. This innovation triumphantly shatters the constraints of traditional reverse osmosis membrane development with two pivotal advancements:
Ultra-Thin Separation Layer: Through the strategic use of advanced polymer interface nanotechnology, our team has achieved an astounding reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously capped at 100 nm. This remarkable breakthrough significantly boosts water flux, leading to a stellar enhancement in permeability.
Enhanced Performance: The infusion of nanoparticles and specially designed hydrophilic polymers has ushered in revolutionary advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and resistance to oxidation.
When compared to traditional polyamide reverse osmosis membranes, Proshare's revolutionary innovation showcases exceptional breakthroughs in four critical aspects:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modification, we create ultra-thin, meticulously ordered separation layers through state-of-the-art polymer interface nanotechnology. This technique transcends the limitations of traditional polyamide membranes in terms of thickness uniformity and material variety.
Enhanced Water Flux and Energy Efficiency
By refining the meticulous layer-by-layer self-assembly process, the functional layer's thickness is expertly moderated, achieving an impressive 3x reduction when compared to traditional membranes. The outcome is >3x increased water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Unmatched Chemical Stability
Transitioning beyond polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These materials display outstanding oxidation resistance capabilities (withstanding exposure to 10 ppm chlorine) and remarkable pH resilience (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle of <10°) combined with robust nanoparticle reinforcement dramatically minimizes organic fouling propensity by 50%. This advance extends chemical cleaning cycles from 3 months to an impressive 6 months, while slashing maintenance costs by 40%.
