- Decreases cleaning frequency by an impressive up to 50%
due toTFN membrane's outstanding anti-fouling attributes, significantly reducing microorganism and inorganic contamination, thus minimizing cleaning needs.
- Cut Operating Expenses (OPEX) by 30%-50%
thanks to unparalleled cleaning performance, robustness, and durability, facilitated by an extensive cleaning pH range and excellent chemical tolerance.
Key Applications:
Ideal for softening, producing pure water, and water reuse in
industries including pharmaceuticals, electronics, power, petrochemical, refinery, food & beverage, and municipal applications.
A typical issue with RO membrane elements is fouling. While fouling doesn't alter the RO membrane's structure, it can drastically impact performance due to surface foulant accumulation.
Proshare's Extreme Anti-Fouling reverse osmosis (RO)technologycombats fouling by implementing an proprietary hydrophilic coating on the membrane surface, ensuring long-term, stable operation. By inhibiting fouling, cleaning frequency is reduced, ultimately leading to lower OPEX in water treatment facilities.
Proshare's Extreme Anti- Fouling membrane is perfectly suited for treating urban sewage water in industrial applications.

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships was dominated by a select few international brands. The variability in feed water quality, such as salinity and temperature, along the cruise ship's journey requires membranes to be adaptable to diverse conditions, all while ensuring consistent water production to meet the rigorous demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have demonstrated remarkable performance, achieving exceptional desalination rates and steady water production. The quality of water produced surpasses the stringent requirements set by luxury cruise ships.
This outstanding performance led to the replacement of existing desalination membranes on three more cruise ships. Proshare's triumph marks it as the first national brand to secure international luxury cruise ship orders for desalination RO membranes, a significant milestone.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has ingeniously crafted a trailblazing generation of reverse osmosis membranes, utilizing the groundbreaking polymer interface nano-self-assembly technology. This innovation shatters the constraints of conventional membrane development, thanks to two major breakthroughs:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, we have succeeded in crafting a separation layer that sets a new standard in thinness-three times thinner than the traditional polyamide thin film, which previously stood at 100 nm. This remarkable advancement dramatically boosts water flux, leading to an unprecedented leap in permeability.
Enhanced Performance: The strategic integration of nanoparticles and specialized hydrophilic polymers has ushered in revolutionary improvements in the hydrophilicity, anti-fouling ability, durability, and oxidation resistance of the membrane.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs across four pivotal areas:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control with nano-doping modification, we've created ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This innovative method transcends the limitations of traditional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we've achieved precise control over the functional layer's thickness, culminating in a remarkable 3x reduction compared to traditional membranes, resulting in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Going beyond polyamide, we employ state-of-the-art hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These materials provide exceptional oxidation resistance (able to withstand 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, boasting a contact angle of less than 10°, combined with nanoparticle reinforcement, dramatically lowers the propensity for organic fouling by 50%. This extends chemical cleaning cycles from 3 to 6 months and reduces maintenance costs by an impressive 40%.
