Farming Applications
Water plays a crucial role in ensuring the well-being of animals (e.g., cattle, chickens, sheep, pigs) and is vital for achieving optimal productivity. However, it is not just the quantity but also the quality of water that significantly impacts the desired growth of animals.
Farms may source water from several origins, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water from civil networks (which contains free chlorine), other sources typically have high levels of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology has proven to be the most effective method to mitigate these adverse effects. The contaminated water used on farms should undergo technological treatment to reduce substances that could be detrimental to animal health.

Proshare - Leading the Way in Innovation Team's Breakthrough in Revolutionary Next-Generation Reverse Osmosis Membrane Technology
Proshare - Pioneering Cutting-Edge Solutions Our team has trailblazed a cutting-edge new generation of reverse osmosis membranes, leveraging groundbreaking polymer interface nano-self-assembly technology. This remarkable development transcends the traditional barriers faced in reverse osmosis membrane design, thanks to two pivotal advancements that we've achieved:
Ultra-Thin Separation Layer for Superior Performance: Through the strategic use of polymer interface nanotechnology, our team has triumphantly diminished the separation layer's thickness, achieving an unprecedented reduction to at least three times thinner than conventional polyamide thin films, which were previously constrained at 100 nm. This monumental breakthrough drastically amplifies water flux, leading to a remarkable surge in permeability.
Enhanced Performance and Unparalleled Durability: By incorporating nanoparticles and specialized hydrophilic polymers, we've orchestrated groundbreaking advancements in our membrane technology, significantly boosting its hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation highlights decisive breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films for Cutting-Edge Applications
With the fusion of nano-scale precision control and nano-doping modification, we master the creation of ultra-thin, highly orderly separation layers through polymer interface nanotechnology. This avant-garde approach effectively overcomes conventional polyamide membrane constraints related to thickness uniformity and material diversity.
Enhanced Water Flux and Unmatched Energy Efficiency
By refining the layer-by-layer self-assembly process, we've precisely regulated functional layer thickness, achieving a formidable 3x reduction compared to traditional membranes. This innovation culminates in >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the bounds of polyamide, our team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) along with ceramic-organic hybrids. These advanced materials showcase remarkable oxidation resistance (withstand exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering for Extended Durability
The superhydrophilic surface, characterized by a contact angle of less than 10°, when combined with nanoparticle reinforcement, notably diminishes organic fouling propensity by 50%. This advancement extends chemical cleaning cycles from 3 months to an impressive 6 months and reduces maintenance costs by a substantial 40%.
