Hospitality/Seawater and Brackish Water Desalination Applications
With a wealth of experience in desalination technologies, Proshare extends its prowess to the civil water sector, particularly in hotels and tourist resorts. Supplying fresh water is crucial in these infrastructures, and our RO seawater or brackish water desalination solutions are precisely engineered to meet the expansive demands of burgeoning tourist locales, ensuring a reliable and efficient water supply.
Farming applications
Water is a vital component in ensuring the health and productivity of livestock, including cattle, chickens, sheep, and pigs. Achieving peak animal performance depends not only on water quantity but significantly on its quality.
Farms secure their water from various origins such as water wells, municipal networks, and to a lesser degree, rivers and other surface sources.
Excluding municipal network-sourced water (which contains free chlorine), other sources typically contain elevated levels of dissolved and suspended solids, along with pathogens. Reverse osmosis technology has proven to be exceptionally effective in mitigating these adverse effects. Thus, it's recommended that farm water undergoes technological treatment to remove harmful substances.

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes in international luxury cruise ships has been the domain of a select few international giants. The ever-changing quality of feed water, due to salinity and temperature fluctuations as the cruise ships voyage through diverse waters, demands membranes that can adapt seamlessly. These membranes must provide dependable and stable water output to fulfill the rigorous demands of ocean-faring vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set a new benchmark with their outstanding desalination rate and unyielding water production stability. The water quality achieved by these membranes not only meets but exceeds the high standards required by luxury cruise liners.
This exceptional performance catalyzed the replacement of desalination membranes on three additional cruise ships, marking a significant triumph for Proshare. This milestone positions Proshare as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Proshare Trailblazing Achievements in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare The team at Proshare has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes. Harnessing the power of polymer interface nano-self-assembly technology, they have effectively surpassed the constraints of conventional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has dramatically thinned the separation layer, rendering it at least three times slimmer than the standard polyamide thin film, which was previously constrained to 100 nm. This monumental leap forward significantly augments water flux, remarkably enhancing permeability.
Superior Enhanced Performance: By incorporating advanced nanoparticles and uniquely specialized hydrophilic polymers, we have achieved unparalleled breakthroughs in the membrane's hydrophilicity, anti-fouling capabilities, robustness, and oxidation resistance.
When juxtaposed with traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in these four crucial aspects:
Self-Assembled Nanocomposite Films
Our integration of nano-scale precision control paired with nano-doping modification masterfully crafts ultra-thin, impeccably ordered separation layers through advanced polymer interface nanotechnology. This revolutionary approach transcends 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 thickness is precisely calibrated, achieving an impressive 3x reduction compared to traditional membranes. This innovation culminates in >3x greater water flux while ensuring a 30% decrease in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond the realm of polyamide, our team deploys cutting-edge hydrophilic polymers (such as modified polysulfones) alongside ceramic-organic hybrids. These avant-garde materials exhibit extraordinary oxidation resistance (effortlessly withstanding 10 ppm chlorine exposure) and impressive pH tolerance (maintaining stability within a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Boasting a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles, our innovation reduces the propensity for organic fouling by 50%, thereby extending the chemical cleaning cycles from three to six months and slashing maintenance costs by 40%.
