Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology has been successfully applied to water desalination for civil use in hotels and tourist resorts. Fresh water supply is crucial for these infrastructures, and reverse osmosis (R.O.) seawater or brackish water desalination provides an alternative solution that can meet the growing water demands of rapidly expanding tourist areas.
Farming applications
Water is a vital resource to ensure the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Both the quantity and the quality of water play an essential role in the desired growth and performance of these animals.
Farm water sources include water wells, civil water networks, and occasionally rivers and other surface sources. To maintain optimal animal health, water from these sources, especially those not from civil networks (which contain free chlorine), must undergo reverse osmosis treatment. This technology is highly effective in reducing dissolved solids, suspended particles, and pathogens that can negatively impact animal welfare.
Given that water from civil networks often contains free chlorine, other sources typically have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these negative effects, ensuring that contaminated water used in farms is treated to remove harmful substances for safer animal consumption.

Proshare Pioneering the Future: Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This milestone surmounts the conventional barriers faced in traditional reverse osmosis membrane development via two groundbreaking advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, our team triumphantly reduced the separation layer's thickness to at least a third of the conventional polyamide thin film (previously constrained to 100 nm). This innovation significantly boosts water flux, resulting in a considerable enhancement in permeability.
Augmented Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has led to transformative developments in the membrane's hydrophilicity, anti-fouling capacity, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshareachieves breakthroughs in four essential areas:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control and nano-doping modification, we create ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovative approach transcends the conventional limitations of polyamide membranes concerning thickness uniformity and material diversity.
Improved Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This results in more than 3x increased water flux coupled with 30% reduced energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Surpassing polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials showcase unparalleled oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH stability (remaining stable in a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, drastically reduces organic fouling likelihood by 50%. This extends chemical cleaning intervals from 3 months to a notable 6 months and slashes maintenance expenses by 40%.
