- Reduced Cleaning Frequency:The TFN membrane's superior anti-fouling performance significantly diminishes the presence of microorganisms and inorganic pollutants, leading to a reduced need for frequent cleanings.
- Wide Cleaning pH Range (1-13):Delivers unrivaled cleaning efficiency, robustness, and longevity due to its extensive cleaning pH range and exceptional chemical tolerance.
Key applications:
Ideal for softening, producing pure water, and water reuse in diverse sectors such as
pharmaceuticals, electronics, power, petrochemical, refinery, food & beverage, and municipal industries.
A prevalent issue with RO membrane elements is fouling. While fouling does not alter the inherent structure of RO membranes, deposits on the membrane surface can drastically impair its efficiency.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling through an innovative hydrophilic coating on the membrane surface, ensuring long-term stable operations. By hindering fouling, the reduced cleaning frequency significantly lowers the operational expenses (OPEX) at water treatment plants.
Proshare Anti- Fouling is perfectly suited for treating urban sewage water to meet the rigorous demands of industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes. Utilizing the revolutionary polymer interface nano-self-assembly technology, we have tackled the constraints of traditional membrane development through two pivotal breakthroughs:
Ultra-Thin Separation Layer: Through the adept application of polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness, making it over three times thinner than conventional polyamide thin films, previously confined to 100 nm. This milestone dramatically boosts water flux, resulting in a notable enhancement in permeability.
Enhanced Performance: By infusing nanoparticles and exclusive hydrophilic polymers, we have achieved monumental strides in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovative approach leads to breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
Harnessing nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This pioneering method surpasses conventional polyamide membranes' limitations in thickness uniformity and material variability.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly technique, we precisely regulate the functional layer thickness, slashing it by 3x compared to traditional membranes. This delivers >3x higher water flux while ensuring 30% lower energy consumption,.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, our team employs state-of-the-art hydrophilic polymers (like modified polysulfones) and ceramic-organic hybrids. These materials display extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and offer pH tolerance (stable across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°) coupled with nanoparticle reinforcement substantially reduces organic fouling tendency by 50%, extending chemical cleaning intervals from 3 to 6 months, and trimming maintenance costs by 40%.
