Our R.O. sea water or brackish water desalination solutions effectively meet the burgeoning water demands of rapidly expanding tourist areas.
Farming applications
In the realm of agriculture, water plays a pivotal role in ensuring the optimal health and productivity of livestock such as cattle, chickens, sheep, and pigs. It's not just the quantity of water that matters but also its quality, which greatly influences animal growth and performance.
Farm water can originate from a diverse array of sources including water wells, public water networks, and, to a lesser extent, rivers and other surface sources.
Excluding water from civil networks, which contain free chlorine, all other sources often have high concentrations of dissolved and suspended solids as well as pathogens. Reverse osmosis technology stands as the premier solution to mitigate these adverse effects. Farms must employ this technological treatment to diminish harmful substances in water that could impact animal health.

Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Traditionally, international luxury cruise liners have relied on a select few global brands for desalination membranes. Given that a cruise ship's route influences water characteristics-such as salinity and temperature-the membranes must be versatile and consistently produce high-quality water, fulfilling the demands of these ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set new standards in both desalination efficiency and consistent water production. The pristine water quality provided by these membranes meets the rigorous standards set by luxury cruise ships.
This outstanding achievement led to the upgrade of desalination systems on three more cruise ships. Proshare's remarkable performance marks it as the pioneering national brand securing international luxury cruise ship orders for desalination RO membranes.
A Complete Water Treatment Plant for Generating Ultra-pure Water in Semiconductor Industry
It is universally acknowledged that the requirements for electronic-grade ultra-pure water's desalination rate are exceptionally stringent, with only a handful of brands meeting these exacting standards.

Proshare Revolutionary Breakthrough by Our Team in Advanced Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously developed a pioneering generation of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology, shattering the constraints of traditional membrane technology with two monumental advancements:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, we have dramatically minimized the separation layer thickness to a groundbreaking level-three times thinner than conventional polyamide thin films, which were previously constrained to 100 nm. This monumental innovation markedly enhances water flux and ushers in a new era of improved permeability.
Elevated Performance: The strategic incorporation of nanoparticles and specially designed hydrophilic polymers has precipitated extraordinary advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new industry standards.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have engineered ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This approach transcends the limitations of conventional polyamide membranes in terms of thickness consistency and material diversity.
Optimized Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer thickness is precisely governed, resulting in a 3x thickness reduction compared to traditional membranes. Consequently, this leads to over 3x increase in water flux and a remarkable 30% decrease in energy consumption.
Revolutionary Polymer Materials with Unparalleled Chemical Stability
Surpassing the realm of polyamide, our team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids that demonstrate exceptional oxidation resistance (enduring up to 10 ppm chlorine exposure) and pH resilience (maintaining stability across the 1-12 pH spectrum).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle less than 10°) synergized with nanoparticle reinforcement significantly curtails organic fouling tendencies by 50%, extending chemical cleaning intervals from 3 to 6 months and slashing maintenance expenses by an impressive 40%.
