Farming Applications

Water is vital in ensuring the optimal health of animals such as cattle, chickens, sheep, and pigs, and in driving their best productive performance. It's not only the volume of water that matters, but its quality significantly influences the desired growth rates of animals.
Farm water can originate from diverse sources, including water wells, civil water networks, and occasionally from rivers or other surface water sources. Each source poses unique challenges for ensuring water quality.
Excluding civil network water (often containing free chlorine), other sources typically exhibit high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these adverse effects. Contaminated farm water must undergo technological treatments to eliminate harmful substances, ensuring the well-being of animals.

Our Advantages

Proshare Pioneering Leap in Advanced Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously crafted a revolutionary new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have transcended the traditional limitations of reverse osmosis membrane development with two pivotal breakthroughs:
Ultra-Thin Separation Layer Mastery: Through the use of polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to at least three times thinner than the conventional polyamide thin films, previously restricted to a thickness of 100 nm. This innovation not only significantly enhances water flux but also achieves a remarkable improvement in permeability.
Unmatched Performance Enhancement: The inclusion of nanoparticles alongside specially designed hydrophilic polymers has spearheaded revolutionary advancements in the membrane's hydrophilicity. This advancement also boosts anti-fouling capability, durability, and oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Prosharehas introduced groundbreaking innovations in four crucial dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modification, we enable the creation of ultra-thin, highly ordered separation layers using advanced polymer interface nanotechnology. This method overcomes the conventional polyamide membranes' constraints in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely managed, achieving a remarkable threefold reduction compared to traditional membranes. This translates into over 3 times higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Unmatched Chemical Resilience
Pushing beyond polyamide, our team employs advanced hydrophilic polymers (such as modified polysulfones) alongside ceramic-organic hybrids, which exhibit extraordinary resistance to oxidation (able to endure 10 ppm chlorine exposure) and pH tolerance (maintaining stability within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, paired with nanoparticle reinforcement, diminishes organic fouling risk by 50%. This advancement extends chemical cleaning cycles from three months to six months, resulting in a 40% reduction in maintenance expenses.
