A prevalent issue with RO membrane elements is fouling. While fouling does not alter the structure of RO membrane elements, it significantly hampers performance due to foulant accumulation on the membrane surface.
Proshare's Extreme Anti-Fouling Reverse Osmosis (RO) strategy effectively combats fouling through an exclusive hydrophilic coating that maintains long-term stable operation. This prevention of fouling results in decreased cleaning frequency and contributes to a reduction in overall OPEX at water treatment facilities.
Proshare's Extreme Anti- Fouling solution perfectly meets the demands of treating urban sewage water for industrial applications.

Agricultural Applications
Water is indispensable for ensuring the health and productivity of livestock (such as cattle, chickens, sheep, pigs). The quality of water, not just its quantity, significantly influences animal growth and performance, underscoring the importance of water quality management in agriculture.
Farms derive water from various sources, including wells, civil water networks, and occasionally from rivers and other surface sources.
Outside of civil networks (which contain free chlorine), other water sources frequently have high levels of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology has proven the most effective for mitigating these adverse effects, by ensuring contaminated farm water undergoes technological treatment to minimize harmful substances for livestock health.
Proshare PSI MEMBRANE Desalination RO Membrane Caters to Desalination Needs Luxury Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been the realm of a select few global brands. The journey of a cruise ship introduces varying feedwater conditions, such as fluctuating salinity and temperature. As such, these membranes must seamlessly adapt to diverse conditions while maintaining consistent water production to fulfill the demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibited outstanding performance, achieving an exceptional desalination rate and providing stable water production. The resultant water quality from these membranes perfectly matched the rigorous standards set by the cruise ship.
This outstanding result instigated the replacement of desalination membranes on three more cruise ships, propelling Proshare to become the pioneer national brand securing international luxury cruise ship orders for desalination RO membranes.

Proshare Pioneering Advances in Next-Level Reverse Osmosis Membrane Technology
Proshare Our team has creatively spearheaded a revolution in reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. We have surmounted the traditional development barriers of reverse osmosis membranes through two pivotal innovations:
Ultra-Thin Separation Layer: Utilizing the groundbreaking polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to a third of the conventional polyamide thin film's thickness (previously capped at 100 nm). This innovative leap forward dramatically boosts water permeability and elevates water flux to new heights.
Superior Performance Enhancement: The infusion of nanoparticles and advanced hydrophilic polymers has catalyzed monumental strides in the membrane's capacity to repel fouling, endure wear, and resist oxidation, vastly improving its hydrophilicity along the way.
In stark contrast to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation sets new benchmarks across four critical domains:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping techniques, we construct exceptionally thin and precisely ordered separation layers using polymer interface nanotechnology. This novel approach transcends the limitations of traditional polyamide membranes, offering unprecedented consistency in thickness and a broader array of materials.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly method, we precisely control the functional layer's thickness, achieving a remarkable 3x reduction compared to traditional membranes. The result: >3x greater water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Venturing beyond polyamide, our team harnesses state-of-the-art hydrophilic polymers, like enhanced polysulfones, and ceramic-organic hybrid materials. These advanced materials demonstrate phenomenal oxidation resistance (withstanding up to 10 ppm chlorine exposure) and extraordinary pH range durability (maintaining stability across a pH spectrum of 1 to 12).
Revolutionary Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle of less than 10°) coupled with nanoparticle fortification minimizes organic fouling by 50%. This advancement significantly extends chemical cleaning intervals from every 3 months to every 6 months, while slashing maintenance costs by 40%.
