Farming applications
Water is vital for ensuring the well-being and productivity of livestock, such as cattle, chickens, sheep, and pigs. Beyond quantity, water quality significantly impacts the growth and performance of animals.
Farm water can originate from a variety of sources, including water wells, urban water networks, and occasionally from rivers and other surface sources.
Excluding urban-supplied water (which contains free chlorine), most other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective in mitigating these adversities. Therefore, water utilized in farms must undergo advanced treatment to eliminate harmful substances detrimental to animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our groundbreaking team has innovatively crafted a new era of reverse osmosis membranes built on the cutting-edge polymer interface nano-self-assembly technology. This marvel of engineering has shattered the constraints of traditional development with two monumental advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, our team has triumphantly reduced the thickness of the separation layer, making it at least three times thinner than the conventional polyamide thin films, which were restricted to a cumbersome 100 nm. This pivotal breakthrough empowers a significant leap in water flux, dramatically boosting permeability.
Enhanced Performance: Through the innovative incorporation of nanoparticles and specially engineered hydrophilic polymers, we've achieved transformative advancements. Our membrane now boasts unparalleled hydrophilicity, superior anti-fouling capabilities, impressive durability, and exceptional oxidation resistance.
Compared to the conventional polyamide reverse osmosis membranes, Proshare's visionary innovation sets new standards with groundbreaking breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with sophisticated nano-doping modification allows the creation of ultra-thin, highly ordered separation layers using state-of-the-art polymer interface nanotechnology. This revolutionary approach resolves the challenges of traditional polyamide membranes in achieving uniform thickness and material versatility.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a remarkable 3x reduction compared to standard membranes. This innovation results in >3x greater water flux and a significant 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Transcending the limitations of polyamide, our team employs cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These advanced materials demonstrate remarkable oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability in a wide pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with an impressively low contact angle of less than 10°, combined with the strength of nanoparticle reinforcement, dramatically cuts organic fouling potential by 50%. This enhancement extends chemical cleaning intervals from 3 to 6 months, slashing maintenance costs by an impressive 40%.
