Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology has also been successfully applied to the realm of water desalination for civil use in hotels and touristic resorts. Freshwater is indispensable for such infrastructure, and R.O. seawater or brackish water desalination offers a viable alternative solution capable of meeting the increased water demands of fast-growing touristic areas.
Farming applications
Water is vital to ensure the health and productivity of animals (such as cattle, chickens, sheep, pigs) and to achieve optimal performance. The quality of water, in addition to its quantity, significantly impacts the desired growth and productivity of livestock.
Farm water sources may include wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Ensuring the quality of this water is pivotal to animal health and performance.
Excluding civil network water, which contains free chlorine, most other sources typically possess high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these adverse effects. Contaminated farm water should undergo technological treatment to reduce harmful substances, thus safeguarding animal well-being.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The innovative team at Proshare has ingeniously crafted a pioneering generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, they have surpassed the constraints of conventional reverse osmosis membrane development with two groundbreaking advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the traditional polyamide thin film, which was previously confined to 100 nm. This revolutionary advancement dramatically boosts water flux, resulting in a significant surge in permeability.
Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, Proshare has achieved unprecedented progress in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, marking a new era in membrane technology.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation demonstrates breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
Through the amalgamation of nano-scale precision control and nano-doping modification, ultra-thin, intricately ordered separation layers are created via polymer interface nanotechnology. This revolutionary approach surpasses the limitations seen in conventional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, realizing a 3x reduction compared to traditional membranes. Consequently, this innovation results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, the team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These groundbreaking materials exhibit outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The incorporation of a superhydrophilic surface (contact angle <10°) coupled with nanoparticle reinforcement significantly curtails organic fouling propensity by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%.
