Farming applications
Water plays a critical role in ensuring the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. It's not just the quantity but the quality of water that significantly impacts the desired growth and performance of these animals.
Farms may source water from diverse origins, such as water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
While water from civil networks may contain free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology proves to be the most effective solution for mitigating the negative impacts of contaminated water used in farms, ensuring it undergoes treatment to reduce substances potentially harmful to animals.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a new era of reverse osmosis membranes, harnessing the cutting-edge polymer interface nano-self-assembly technology. This innovation triumphantly surpasses the traditional development hurdles of reverse osmosis membranes, brought forth by two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the artful application of polymer interface nanotechnology, our team has meticulously thinned the separation layer, achieving dimensions at least three times thinner than the conventional polyamide thin film (historically constrained to 100 nm). This remarkable breakthrough vastly enhances water flux, culminating in a notable leap in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and bespoke hydrophilic polymers has ushered in revolutionary advancements in the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation achieves remarkable progress across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By seamlessly blending nano-scale precision control with nano-doping modification, we have crafted ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This technique addresses the limitations of conventional polyamide membranes concerning thickness uniformity and material variety.
Enhanced Water Flux and Energy Efficiency
The optimization of the layer-by-layer self-assembly process ensures precise functional layer thickness control, achieving a remarkable 3x reduction compared to traditional membranes. This innovation results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from the confines of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials showcase incredible oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface, with a contact angle of less than 10°, along with nanoparticle reinforcement, diminishes organic fouling propensity by 50%. This advancement extends chemical cleaning intervals from 3 months to an impressive 6 months, slashing maintenance costs by 40%.
