Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is also harnessed in the civil water desalination landscape for hotels and touristic resorts. Ensuring a fresh water supply is vital for such infrastructures, and our R.O. seawater or brackish water desalination solutions are designed to meet the escalating capacities and burgeoning water demands of rapidly expanding touristic hubs.
Farming applications
Water quality is indispensable for ensuring the optimal health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Not just the quantity, but the quality of water plays a critical role in achieving desired growth and performance in livestock.
On farms, water can be sourced from a variety of origins, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources.
Excluding civil network water, which contains free chlorine, alternative sources often harbor high concentrations of dissolved solids, suspended matter, and pathogens. Reverse osmosis technology has proven to be the most effective means of mitigating these detrimental effects. Contaminated farm water requires thorough technological treatment to minimize substances that could harm the animals.

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 employing cutting-edge polymer interface nanotechnology, our team has achieved an incredible feat by reducing the separation layer thickness to at least three times thinner than the traditional polyamide thin film (previously capped at 100 nm). This remarkable breakthrough significantly boosts water flux, leading to an outstanding improvement in permeability.
Enhanced Performance: With the introduction of nanoparticles and specialized hydrophilic polymers, we have pioneered significant advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new standards in membrane technology.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases groundbreaking breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This approach transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity, revolutionizing membrane design.
Enhanced 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 reduction of threefold compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, our team employs advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials exhibit exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and remarkable pH tolerance (remaining stable in a pH range of 1-12).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) reinforced by nanoparticles, we significantly reduce organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by 40%.
We proudly hold the following prestigious certifications, which stand as a testament to our commitment to excellence and sustainability: Health & Safety Management System Certificate, Environmental Management System Certificate, and the ISO9001 Quality System Certificate.
