Farming applications
Water quality is paramount in ensuring optimal health and productivity of livestock such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water play critical roles in animal growth and performance, influencing the overall outcomes of farming operations.
Farming operations draw water from a variety of sources including wells, civil water networks, and less commonly from rivers and surface sources. Ensuring quality across these diverse origins is crucial for maintaining the health of livestock.
Beyond civil water networks containing free chlorine, other water sources often contain high levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology stands out as the most effective solution to mitigate these negative impacts. Contaminated farm water must undergo technological treatment to eliminate harmful substances and safeguard animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The team at Proshare has pioneered an extraordinary leap in reverse osmosis membrane technology. Utilizing cutting-edge polymer interface nano-self-assembly techniques, they have shattered the confines of traditional development with two significant advancements:
Ultra-Thin Separation Layer: Through the remarkable application of polymer interface nanotechnology, our team has managed to thin the separation layer to an astonishing degree, making it at least three times thinner than the previous standard polyamide thin film of 100 nm. This monumental breakthrough drastically enhances water flux and ushers in a new era of permeability.
Enhanced Performance: By integrating nanoparticles and tailored hydrophilic polymers, we have achieved unprecedented strides in advancing the membrane's hydrophilicity, bolstering its anti-fouling capabilities, enhancing durability, and vastly improving oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation stands as a beacon of progress, showcasing advancements across four pivotal domains:
Self-Assembled Nanocomposite Films
The seamless fusion of nano-scale precision control and nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This revolutionary method surmounts the challenges faced by conventional polyamide membranes, particularly in achieving thickness uniformity and diversifying material composition.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the thickness of the functional layer is precisely controlled, culminating in a reduction that is three times less than that of traditional membranes, resulting in >3x heightened water flux and a remarkable 30% decrease in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking free from the confines of polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These avant-garde materials exhibit exceptional resilience against oxidation (withstanding exposure to up to 10 ppm of chlorine) and robust pH tolerance (maintaining stability across a pH range of 1 to 12).
Anti-Fouling Surface Engineering
The synergistic combination of a superhydrophilic surface, with a contact angle of less than 10°, and nanoparticle reinforcement effectively diminishes the tendency for organic fouling by 50%. This enhancement effectively doubles the chemical cleaning cycle duration from 3 to 6 months, while simultaneously reducing maintenance costs by an impressive 40%.
