Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's profound experience in desalination technology is harnessed to enhance water desalination for civil purposes in hotels and touristic resorts. Freshwater supply is crucial for these infrastructures, and our R.O. seawater or brackish water desalination solutions are tailored to meet the burgeoning demands of these rapidly expanding touristic zones.
Farming applications
Water is indispensable for ensuring optimal health and productivity in farming animals such as cattle, chickens, sheep, and pigs. The quality of water, beyond just its quantity, is pivotal in influencing the desired growth and productivity of livestock.
Farm water can originate from a myriad of sources, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources.
Except for water from civil networks, which contains free chlorine, other sources typically have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient way to mitigate these adverse effects, ensuring the water used in farms undergoes comprehensive treatment to remove harmful substances.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a new generation of reverse osmosis membranes based on polymer interface nano-self-assembly technology, overcoming the limitations of traditional reverse osmosis membrane development through two key advancements:
Ultra-Thin Separation Layer: By harnessing state-of-the-art polymer interface nanotechnology, the team has achieved remarkable success in reducing the separation layer's thickness to an unprecedented level-at least three times thinner than the conventional polyamide thin film's 100 nm threshold. This pioneering approach dramatically boosts water flux, achieving a phenomenal improvement in permeability.
Enhanced Performance: Through the strategic incorporation of nanoparticles and specialized hydrophilic polymers, we have unlocked groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation demonstrates breakthroughs in four key aspects:
Self-Assembled Nanocomposite Films
The integration of nano-scale precision control and nano-doping modification enables the creation of ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This sophisticated approach transcends the limitations of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, achieving a remarkable 3x reduction compared to traditional membranes. This innovation results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These advanced materials showcase exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface (with a contact angle less than 10°), reinforced by nanoparticles, significantly reduces the propensity for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 months to 6 months, simultaneously slashing maintenance costs by an impressive 40%.
