Farming Applications
Water is the lifeblood of agriculture, crucial for ensuring the optimal health of animals such as cattle, chickens, sheep, and pigs, thereby enhancing their productivity. However, achieving the desired growth in animals depends not only on the availability of water but significantly on its quality as well.
In farms, water can be sourced from various origins, including water wells, civil water networks, and to a lesser extent, rivers, and other surface sources.
Aside from water sourced from civil networks, which typically contains free chlorine, other sources often possess high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology emerges as the most effective solution to mitigate negative effects. Contaminated water in farms should undergo comprehensive technological treatment to eliminate harmful substances, safeguarding animal health and optimizing farm productivity.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously crafted a pioneering generation of reverse osmosis membranes by harnessing polymer interface nano-self-assembly technology. This innovation transcends the constraints faced by traditional reverse osmosis membrane development, marked by two transformative advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, the team has achieved an impressive reduction in the separation layer's thickness, creating a layer at least three times thinner than the conventional polyamide thin film (previously limited to 100 nm). This remarkable feat substantially enhances water flux, ushering in significant improvements in permeability and efficiency.
Enhanced Performance: Through the integration of nanoparticles and specialized hydrophilic polymers, we have catalyzed revolutionary advancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting a new standard in membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation heralds breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
The synergy of nano-scale precision control and nano-doping modification enables the crafting of ultra-thin, highly ordered separation layers through revolutionary polymer interface nanotechnology. This approach triumphs over the limitations of conventional polyamide membranes in terms of uniform thickness and a rich diversity of materials.
Enhanced Water Flux and Energy Efficiency
Through meticulous refinement of the layer-by-layer self-assembly process, the functional layer's thickness is precisely controlled, achieving a 3x reduction compared to traditional membranes. This precision engineering delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the realm of polyamide, our team exploits advanced hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials showcase unparalleled oxidation resistance capable of withstanding 10 ppm chlorine exposure and demonstrate remarkable pH tolerance maintaining stability across a pH range of 1-12.
