Farming applications

Water quality is pivotal to ensuring the health and optimal productivity of farm animals, such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water affect animal growth and performance, underscoring the necessity for high-standard water management in farming.
Farm water can originate from water wells, civil water networks, and, to a lesser degree, rivers and other surface sources. Our advanced water management solutions ensure that every drop of water meets the stringent quality standards required for optimal farming performance.
Apart from water from civil networks, which contains free chlorine, other sources often harbor high concentrations of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology stands out as the most effective method to mitigate their adverse effects. Contaminated farm water undergoes rigorous treatment to eliminate substances harmful to animals, safeguarding their health and productivity.

Successful Cases Reference

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has achieved a remarkable breakthrough in developing a new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have effectively conquered the constraints of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Through the revolutionary application of polymer interface nanotechnology, our team has successfully crafted a separation layer that is at least three times thinner than conventional polyamide films, which were confined to a thickness of 100 nm. This groundbreaking reduction not only significantly boosts water flux but also dramatically elevates permeability.
Enhanced Performance: By incorporating nanoparticles and uniquely engineered hydrophilic polymers, we have achieved revolutionary enhancements in the membrane's hydrophilicity, anti-fouling capabilities, longevity, and oxidation resistance, setting a new standard in the field.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases significant advancements in four crucial dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we have pioneered the production of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This novel method transcends the typical limitations of conventional polyamide membranes, specifically in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our optimization of the layer-by-layer self-assembly process enables precise control over the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes. This innovation leads to an impressive >3x increase in water flux while also slashing energy consumption by an outstanding 30%.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the boundaries of polyamide, our team employs state-of-the-art hydrophilic polymers, including modified polysulfones, and innovative ceramic-organic hybrids. These advanced materials demonstrate exceptional oxidation resistance (enduring exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our membranes feature a superhydrophilic surface with an impressively low contact angle of <10°, reinforced by nanoparticles to reduce organic fouling by 50%. This advancement doubles the chemical cleaning cycle from 3 to 6 months, and slashes maintenance costs by an exceptional 40%
