Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive expertise in desalination technology is harnessed to facilitate water desalination for civil use in hotels and tourist resorts. Ensuring a steady supply of fresh water is vital for these infrastructures. Our R.O. seawater and brackish water desalination solutions efficiently meet the burgeoning water demands of rapidly expanding tourist areas, accommodating their growing capacities.
Farming applications
Water is indispensable in maintaining animal health and achieving optimal productivity in livestock such as cattle, chickens, sheep, and pigs. However, the growth and well-being of animals depend not just on the quantity but significantly on the superior quality of water provided.
Water for farms can originate from various sources, including water wells, civil water networks, and, to a lesser degree, from rivers and other superficial sources.
Excluding water from civil networks (often containing free chlorine), other sources typically exhibit high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most efficient method to mitigate these adverse elements. Contaminated water used in farming should undergo advanced technological treatment to eliminate harmful substances, safeguarding the health of the animals.

Proshare Pioneering Breakthroughs: Revolutionizing Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted a new wave of reverse osmosis membranes using polymer interface nano-self-assembly technology. This innovative approach addresses the constraints of traditional membranes with two transformative advancements:
Ultra-Thin Separation Layer: Leveraging state-of-the-art polymer interface nanotechnology, our team has successfully minimized the separation layer thickness to an extraordinary level-three times thinner than the standard polyamide thin film. This achievement dramatically boosts water flux, leading to an impressive leap in permeability.
Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we have achieved remarkable enhancements in hydrophilicity, anti-fouling capabilities, robustness, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshareis proud to showcase groundbreaking advancements in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This method transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By expertly refining the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a 3x reduction compared to traditional membranes. This leads to: >3x dramatic increase in water flux and 30% remarkable reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Advancing beyond polyamide, our team utilizes cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These outstanding materials showcase exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
State-of-the-Art Anti-Fouling Surface Engineering
