Hospitality/Seawater and Brackish Water Desalination Applications
Proshare showcases exceptional prowess in desalination technology, particularly for water purification in hotels and tourist resorts. Ensuring a continuous supply of fresh water is vital for such infrastructures, and our innovative R.O. seawater or brackish water desalination solutions meet the escalating demands of burgeoning touristic zones, providing essential coverage for their water needs.
Farming Applications
Water plays a pivotal role in maintaining the health and productivity of farm animals like cattle, chickens, sheep, and pigs. However, it is not merely the quantity but also the water's quality that significantly influences the growth and performance of these animals.
Farm water originates from diverse sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface water sources.
Apart from civil network water, which contains free chlorine, other sources typically exhibit high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology stands out as the most effective solution to mitigate these adverse effects. The contaminated water used in farms necessitates advanced technological treatment to minimize harmful substances for the animals.

Proshare Revolutionizing Reverse Osmosis with Cutting-Edge Membrane Technology
Proshare Our team has ingeniously crafted a next-gen reverse osmosis membrane utilizing polymer interface nano-self-assembly technology. This revolutionary approach shatters the constraints of traditional membrane development through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging polymer interface nanotechnology, our experts have adeptly minimized the separation layer thickness to at least three times thinner than its conventional polyamide counterparts (previously confined to 100 nm). This scientific marvel drastically boosts water flux, culminating in remarkable permeability enhancements.
Superior Enhanced Performance: The groundbreaking amalgamation of nanoparticles and innovative hydrophilic polymers propels the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance to new heights.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation embodies breakthroughs in four significant dimensions:
State-of-the-Art Self-Assembled Nanocomposite Films
With nano-scale precision and nano-doping modification, our membranes boast ultra-thin, meticulously ordered separation layers, crafted using polymer interface nanotechnology. This avant-garde technique transcends the thickness uniformity and material diversity limitations of conventional polyamide membranes.
Boosted Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is precisely calibrated, achieving a remarkable 3x reduction compared to traditional membranes. This translates into >3x increased water flux and a dramatic 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Our departure from polyamide embraces advanced hydrophilic polymers (like modified polysulfones) and novel ceramic-organic hybrids. These materials boast extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and comprehensive pH tolerance (withstanding stability in a 1-12 pH range).
Pioneering Anti-Fouling Surface Engineering
