Farming applications
Water quality is paramount for ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. It's not just about the quantity but the quality of water that influences desired growth and productivity.
Farms can source water from wells, municipal water networks, and occasionally from rivers or other surface sources. These diverse sources necessitate advanced treatment to ensure safety and quality.
Non-municipal water sources often have high concentrations of dissolved solids and pathogens. Reverse osmosis technology has proven highly effective in mitigating these negative impacts. Contaminated water used in farms should undergo technological treatment to eliminate harmful substances, ensuring animal well-being.

Proshare Trailblazing Breakthroughs in Advanced Reverse Osmosis Membrane Technology
Proshare Our expert team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes, leveraging polymer interface nano-self-assembly technology. This innovation triumphs over the traditional challenges of membrane development through two revolutionary strides:
Ultra-Thin Separation Layer Mastery: Utilizing state-of-the-art polymer interface nanotechnology, we've dramatically thinned the separation layer to merely a fraction-three times thinner than its traditional polyamide counterpart (formerly restricted to 100 nm). This remarkable accomplishment substantially boosts water flux and achieves stellar improvements in permeability.
Enhanced Performance Prowess: Integrating nanoparticles with specialized hydrophilic polymers has catalyzed groundbreaking improvements in the membrane's hydrophilicity, anti-fouling capacity, durability, and resistance to oxidation.
In comparison with conventional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films Precision
By marrying nano-scale precision control with nano-doping modification, ultra-thin and highly ordered separation layers are born through advanced polymer interface nanotechnology. This strategy overcomes the constraints of conventional membranes concerning thickness uniformity and material variety.
Super-Charged Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, a precise reduction in functional layer thickness is achieved, slashing it to a third of traditional membrane thickness. This ingenuity delivers over triple the water flux, accompanied by an impressive 30% decrease in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit unmatched oxidation resistance, enduring 10 ppm chlorine exposure, and pH resilience, maintaining stability across a pH range of 1 to 12.
Revolutionary Anti-Fouling Surface Engineering
The synergy of a superhydrophilic surface (contact angle <10°) with nanoparticle reinforcement drastically reduces the tendency for organic fouling by 50%. This advancement extends chemical cleaning intervals from three months to six months, slashing maintenance costs by a significant 40%.
