Farming applications
Water is vital for ensuring the health and optimal performance of farm animals (e.g., cattle, chickens, sheep, pigs). Not only does the quantity, but the quality of water significantly affects their growth and productivity.
Farm water can originate from diverse sources, including water wells, civil water networks, and occasionally rivers and surface sources.
Excluding water from civil networks, which contains free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these adverse effects, ensuring the technological treatment of contaminated water on farms to reduce harmful substances for animals.

Proshare The Team's Landmark Achievement in Revolutionary Reverse Osmosis Membrane Technology
Proshare Our team has pioneered a groundbreaking new generation of reverse osmosis membranes through the innovative use of polymer interface nano-self-assembly technology, surmounting the challenges posed by traditional membrane development with two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has engineered the separation layer to be at least three times thinner than conventional polyamide thin films (previously restricted to 100 nm). This extraordinary achievement dramatically boosts water flux, delivering a remarkable leap in permeability.
Enhanced Performance: Through the strategic incorporation of nanoparticles and custom hydrophilic polymers, we have unlocked unprecedented improvements in the membrane's hydrophilicity, anti-fouling capacity, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modifications, we can create ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This innovative approach triumphs over the conventional polyamide membranes' limitations in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, resulting in a dramatic 3x reduction compared to traditional membranes. This transformation yields >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Moving beyond the confines of polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These advanced materials demonstrate exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable within a pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
Our superhydrophilic surface (achieving a contact angle <10°) fortified with nanoparticle reinforcement reduces the tendency for organic fouling by 50%. This advancement extends the chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by 40%
