Farming Applications
Water is crucial for guaranteeing the health and productive performance of farm animals (e.g., cattle, chickens, sheep, pigs). Beyond quantity, the water's quality is fundamental to fostering the desired growth of animals.
Farm water sources vary, including wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Quality control is essential for optimal livestock conditions.
Excluding water from civil networks, which contains free chlorine, other sources often have high concentrations of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective in mitigating these negative impacts. Contaminated farm water must be technologically treated to eliminate harmful substances, ensuring animal health and productivity.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our expert team at Proshare has pioneered a revolutionary advancement in reverse osmosis membranes, leveraging the cutting-edge polymer interface nano-self-assembly technology. This innovation pushes beyond the constraints of traditional membrane development through two significant leaps:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, the team has achieved a remarkable reduction in the thickness of the separation layer, making it three times thinner than the conventional polyamide thin film, which was previously confined to a 100 nm limitation. This remarkable stride not only boosts water flux but also brings a dramatic enhancement in permeability.
Enhanced Performance: Through the infusion of nanoparticles and unique hydrophilic polymers, our membrane exhibits groundbreaking advancements in hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new standards in the industry.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Thanks to the integration of nano-scale precision control and nano-doping modification, our technology crafts ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This innovation eradicates the constraints of conventional polyamide membranes, enhancing thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely managed, resulting in a threefold reduction compared to standard membranes. This advancement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Our team transcends traditional polyamide by adopting advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials demonstrate extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable within a 1-12 pH range).
Anti-Fouling Surface Engineering
With a superhydrophilic surface boasting a contact angle of less than 10°, reinforced by nanoparticles, we significantly reduce the tendency for organic fouling by 50%, extending chemical cleaning cycles from 3 months to 6 months, and decreasing maintenance costs by 40%.
