It offers a superior membrane solution with exceptional water purity, enhanced fouling resistance, and reduced energy consumption.
Key Features:
- 30% lower Pressures :Guarantees excellent salt-rejection capabilities with 30% lower operating pressures, enhancing efficiency.
- Reduced Cleaning Frequency:The TFN membrane's outstanding anti-fouling performance significantly minimizes microorganism and inorganic buildup, leading to reduced cleaning frequency.
- Extensive Cleaning pH (1-13) Range:Delivers superior cleaning performance, robustness, and durability thanks to its extensive cleaning pH range and chemical resistance.
Key Applications:
Ideal for softening, producing pure water, and water reuse across industries such as
pharmaceutical, electronics, power, petrochemical, refinery, food & beverage, and municipal sectors.
A common challenge with reverse osmosis (RO) membrane elements is fouling. While fouling does not alter the structure of RO membrane elements, it can significantly diminish performance due to accumulation on the membrane surface.
Proshare Extreme Anti-Fouling reverse osmosis (RO) prevents fouling by employing a unique hydrophilic coating on the membrane surface. This allows for long-term stable operation and, by reducing fouling, decreases cleaning frequency, resulting in lower operational expenditures (OPEX) at the water treatment facility.
Proshare Extreme Anti- Fouling is tailored to meet your needs for treating urban sewage water intended for industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare With unmatched innovation, our Proshare team has pioneered a revolutionary generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This groundbreaking development transcends the traditional bounds of membrane design through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has achieved an unprecedented reduction in the separation layer's thickness, making it at least three times thinner than the standard polyamide thin films, previously confined to a mere 100 nm. This monumental breakthrough not only enhances water flux but also propels permeability to new heights.
Enhanced Performance: Our ingenious use of nanoparticles alongside specialized hydrophilic polymers has resulted in transformative improvements in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance-pioneering advancements that set new benchmarks in performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation sets itself apart by achieving breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
Our integration of nano-scale precision control and innovative nano-doping modification crafts ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This sophisticated method triumphs over the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely minimized, achieving a dramatic 3x reduction when compared to traditional membranes. This innovation results in >3x higher water flux and 30% lower energy consumption,marking a new frontier in membrane efficiency.
Novel Polymer Materials with Superior Chemical Stability
Shattering the constraints of polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials boast exceptional oxidation resistance, withstanding exposure to 10 ppm chlorine, and pH tolerance, remaining stable across a wide range from pH 1 to 12.
Anti-Fouling Surface Engineering
