Farming applications
Water is an essential resource to ensure optimal health and productivity of animals such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water play a crucial role in influencing the desired growth and performance of livestock.
Farm water sources are diverse, originating from water wells, civil water networks, and occasionally from rivers and other surface sources. This variety necessitates a strategic approach to water quality management on farms.
Excluding civil water networks, which contain free chlorine, other sources often exhibit high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these adverse effects. Thus, contaminated farm water should undergo advanced treatment processes to eliminate harmful substances and safeguard animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The innovative minds at Proshare have revolutionized reverse osmosis membranes, leveraging polymer interface nano-self-assembly technology to transcend the limitations of conventional membrane development with two remarkable advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has ingeniously minimized separation layer thickness to at least one-third of the traditional polyamide thin films, previously constrained to 100 nm. This milestone dramatically boosts water flux, ensuring a phenomenal leap in permeability.
Enhanced Performance: The fusion of nanoparticles with advanced hydrophilic polymers has catalyzed astounding enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation unlocks breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
By uniting nano-scale precision control with nano-doping modification, Proshare's cutting-edge technology crafts ultra-thin, highly ordered separation layers. This breakthrough overcomes the traditional polyamide membrane limitations of thickness uniformity and material diversity through polymer interface nanotechnology.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, functional layer thickness is precisely managed to yield a 3x reduction compared to conventional membranes. This innovative approach results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Evolving beyond polyamide, our team employs advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These avant-garde materials offer remarkable resistance to oxidation (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
