Farming applications
Water plays a crucial role in ensuring the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. While quantity matters, the quality of water is equally critical in promoting optimal animal growth and performance.
Farm water sources vary widely, originating from water wells, civil water networks, and occasionally rivers and surface sources. Each source presents unique characteristics that must be managed for optimal water quality.
Excluding chlorine-treated civil networks, most farm water sources tend to have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the best method to mitigate these contaminants, effectively lowering harmful substances in farm water to protect animal health and ensure superior productivity.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a new generation of reverse osmosis membranes based on cutting-edge polymer interface nano-self-assembly technology, triumphing over the constraints of traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: By masterfully employing polymer interface nanotechnology, the team has remarkably reduced the thickness of the separation layer to at least three times thinner than the conventional polyamide thin film (previously limited to 100 nm). This innovative leap significantly enhances water flux, achieving a dramatic improvement in permeability.
Enhanced Performance: The pioneering introduction of nanoparticles and specialized hydrophilic polymers has ushered in groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation stands out with breakthroughs in four key areas:
Self-Assembled Nanocomposite Films
The meticulous integration of nano-scale precision control and nano-doping modification enables the formation of ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This method triumphs over the limitations of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, achieving an impressive 3x reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond traditional polyamide, the team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and robust ceramic-organic hybrids. These materials showcase exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable in a 1-12 pH range).
Anti-Fouling Surface Engineering
The extraordinarily superhydrophilic surface (contact angle <10°) combined with nanoparticle reinforcement dramatically reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months and significantly cutting maintenance costs by 40%.
