- Reduces Cleaning Frequency by up to 50%
:The TFN membrane's outstanding anti-fouling performance significantly reduces microorganisms and inorganic pollutants, leading to a substantial decrease in cleaning frequency.
- Reduces Operational Expenditure (OPEX) by 30%-50%
Delivers highly effective cleaning performance, robustness, and durability due to its extensive cleaning pH range and chemical resistance.
Key Applications:
Ideal for softening, producing pure water, and facilitating water reuse in
pharmaceutical, electronics, power, petrochemical, refinery, food & beverage, municipal sectors, and more.
A prevalent challenge with RO membrane elements is fouling. While fouling does not alter the structure of RO membrane elements, the presence of foulants on the membrane surface can drastically reduce their performance.
Proshare Extreme Anti-Fouling Reverse Osmosis (RO) prevents fouling by utilizing an exclusive hydrophilic coating on the membrane surface, ensuring long-term stable operation. By preventing fouling, the reduced cleaning frequency results in lower OPEX for water treatment plants.
Proshare Extreme Anti- Fouling perfectly meets the demands of treating urban sewage water for industrial applications.

Farming Applications
Water is vital for ensuring animal fitness and achieving optimal productive performance in farming, whether for cattle, chickens, sheep, or pigs. Beyond quantity, the quality of water is equally influential on animal growth and well-being.
Farm water sources vary, originating from wells, civil water networks, and occasionally from rivers and other surface sources. These diverse origins necessitate reliable treatment solutions to maintain water quality.
Excluding civil network water (with free chlorine), other sources often contain high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as the most effective solution, mitigating these negative effects. Thus, farm water should undergo advanced treatment to remove harmful substances, ensuring safe and healthy conditions for animals.
Proshare PSI MEMBRANE: A Beacon of Innovation Desalination RO Membrane: Transforming Seawater into Freshwater Serves Desalination Needs in Diverse Settings Cruise Ship: Elevating Maritime Water Solutions
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. As cruise ships traverse diverse routes, the quality of feed water-such as salinity and temperature-fluctuates, demanding membranes that can adapt to these dynamic conditions. The goal is to ensure stable water production, crucial for meeting the ocean-going vessels' needs.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have showcased exceptional performance, excelling in both desalination rate and the consistency of water production. The quality of water produced not only meets but exceeds the stringent standards required by luxury cruise lines.
This remarkable achievement led to the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this endeavor cements its status as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Proshare Trailblazing Breakthroughs in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has brilliantly pioneered a revolutionary new generation of reverse osmosis membranes through cutting-edge polymer interface nano-self-assembly technology. We've transcended traditional development constraints with two groundbreaking advancements:
Ultra-Thin Separation Layer Marvel: Harnessing the power of polymer interface nanotechnology, our team has achieved a remarkable feat by thinning the separation layer to be at least three times slimmer than conventional polyamide thin films, which were confined to 100 nm. This innovation dramatically boosts water flux, delivering a significant leap in permeability.
Enhanced Performance Excellence: The infusion of nanoparticles and specially designed hydrophilic polymers has ushered in revolutionary improvements in the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resilience.
When benchmarked against conventional polyamide reverse osmosis membranes, Proshare's technological breakthrough showcases advancements across four critical dimensions:
Innovative Self-Assembled Nanocomposite Films
Employing nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This technique surpasses the traditional polyamide membrane's limitations in thickness consistency and material variance.
Unparalleled Water Flux and Energy Efficiency
Through the refined layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a threefold reduction over traditional membranes. This innovation culminates in over three times higher water flux and a 30% reduction in energy consumption.
Advanced Polymer Materials with Superior Chemical Endurance
Breaking away from polyamide, we harness advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These avant-garde materials exhibit extraordinary oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH robustness (maintaining stability across a pH range of 1-12).
Ingenious Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, coupled with nanoparticle reinforcement, slashes organic fouling potential by 50%, doubling the chemical cleaning cycle from 3 to 6 months, and reducing maintenance costs by a substantial 40%.
