Farming Applications

Water is crucial in ensuring the health and optimal performance of animals (such as cattle, chickens, sheep, and pigs). Both the quantity and quality of water significantly impact the desired growth of animals.
Water used on farms can originate from various sources, including water wells, civic water networks, and, to a lesser extent, rivers and other surface sources.
Excluding water from civic networks (which contains free chlorine), other sources typically feature high concentrations of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology has proven to be the most effective in mitigating these negative effects. Contaminated farm water should undergo technological treatment to minimize substances harmful to animals.

Our Advantages

Proshare Team's Groundbreaking Leap in Future-Forward Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes through revolutionary polymer interface nano-self-assembly technology. This advancement triumphantly surpasses the constraints of traditional reverse osmosis membranes with two pivotal innovations:
Revolutionary Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, our team has achieved an incredible feat by reducing the separation layer's thickness to an unprecedented level-at least three times thinner than the traditional polyamide thin film, which was previously capped at 100 nm. This extraordinary development propels water flux to new heights, delivering remarkable improvements in permeability.
Performance Beyond Compare: The groundbreaking infusion of nanoparticles and advanced hydrophilic polymers has revolutionized the membrane's hydrophilicity, anti-fouling ability, robustness, and resistance to oxidation. This innovation sets new standards in membrane performance and longevity.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's transformative innovation achieves unprecedented breakthroughs in four essential domains:
Pioneering Self-Assembled Nanocomposite Films
Utilizing nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via cutting-edge polymer interface nanotechnology. This technique shatters the boundaries of traditional polyamide membranes' uniformity in thickness and material selection.
Superior Water Flux and Optimal Energy Efficiency
Through meticulous refinement of the layer-by-layer self-assembly process, we exert precise control over the functional layer thickness, achieving an impressive 3x reduction compared to conventional membranes. Consequently, this results in >3x enhanced water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Surpassing the limitations of polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and groundbreaking ceramic-organic hybrids. These materials demonstrate remarkable resistance to oxidation (withstanding 10 ppm chlorine exposure) and pH adaptability (stable across a pH range of 1-12).
Sophisticated Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle of <10°) combined with nanoparticle reinforcement drastically reduces organic fouling by 50%, effectively extending the duration between chemical cleanings from 3 months to 6 months and slashing maintenance expenses by 40%.
