Farming Applications
Water is a vital component in ensuring optimal health and productivity of livestock such as cattle, poultry, and sheep. The quality of water, not just its quantity, plays a crucial role in achieving desired growth and productivity levels in animals.
Farms draw water from various sources including wells, civil water networks, and, to a lesser extent, rivers and surface water. Each source has distinct characteristics that influence the overall water quality.
Excluding municipal water networks that contain free chlorine, other water sources often carry high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these impurities, ensuring that farm water is treated to reduce harmful substances, thereby safeguarding animal health.

Proshare Innovation Suzhou Co., Ltd. Revolutionizing Reverse Osmosis: Our Team's Breakthrough in Cutting-Edge Membrane Technology
Proshare Innovation Suzhou Co., Ltd. Our pioneering team has ingeniously crafted a revolutionary generation of reverse osmosis membranes, leveraging the groundbreaking polymer interface nano-self-assembly technology. This innovative approach transcends the constraints of traditional membrane development through two monumental advancements:
Ultra-Thin Separation Layer: A Leap Forward: Harnessing the power of polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer's thickness, now at least three times thinner than conventional polyamide thin films, previously capped at 100 nm. This substantial innovation dramatically enhances water flux, marking a significant leap in permeability performance.
Enhanced Performance: Unmatched Efficiency: Through the strategic integration of nanoparticles and specialized hydrophilic polymers, we have achieved remarkable enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new industry standards.
When compared to traditional polyamide reverse osmosis membranes, Proshare Innovation Suzhou Co., Ltd.'s innovative solutions showcase breakthroughs in four crucial domains:
Self-Assembled Nanocomposite Films: Precision and Performance
By skillfully integrating nano-scale precision control with nano-doping modifications, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This method triumphs over conventional polyamide membranes' limitations, offering improved thickness uniformity and material diversity.
Enhanced Water Flux and Superior Energy Efficiency
With meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, culminating in a 3x reduction when compared to conventional membranes. This leads to more than three times higher water flux and 30% reduced energy consumption.
Novel Polymer Materials with Exceptional Chemical Stability
Surpassing polyamide limitations, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials boast unparalleled oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (stable within a pH range of 1 to 12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle of less than 10°), combined with nanoparticle reinforcement, slashes organic fouling propensity by 50%, extends chemical cleaning cycles from 3 to 6 months, and reduces maintenance costs by a remarkable 40%.
