Farming applications
Water is indispensable for ensuring the health and optimal performance of livestock such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water are crucial for achieving the desired growth and productivity of these animals.
On farms, water can originate from various sources, including water wells, municipal water networks, and to a lesser extent, rivers and other surface sources.
Apart from municipal water networks (which contain free chlorine), other sources typically harbor high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology stands out as the most effective means to mitigate these contaminants. Consequently, farm water must undergo advanced treatment to eliminate harmful substances, safeguarding animal health.

Proshare Team's Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our dynamic team has masterfully crafted a groundbreaking new generation of reverse osmosis membranes, harnessing the revolutionary power of polymer interface nano-self-assembly technology. This advancement conquers the constraints faced by traditional membrane development through two monumental breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, we've achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the former polyamide thin film (previously constrained to 100 nm). This transformative advancement significantly boosts water flux, resulting in a dramatic enhancement in permeability.
Unmatched Enhanced Performance: The infusion of nanoparticles and specialized hydrophilic polymers has paved the way for unprecedented advancements in membrane hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new benchmarks across four pivotal domains:
Revolutionary Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers using advanced polymer interface nanotechnology. This innovative approach transcends the traditional boundaries of polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Optimized Energy Efficiency
By finely tuning the layer-by-layer self-assembly process, the thickness of the functional layer is meticulously controlled, achieving a 3x reduction compared to conventional membranes. This technological leap results in >3x increased water flux alongside a 30% reduction in energy consumption,ushering in a new era of efficiency.
Innovative Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials showcase exceptional resistance to oxidation (capable of withstanding exposure to 10 ppm chlorine) and resilience to pH variations, maintaining stability within a pH range of 1 to 12.
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface, with a remarkably low contact angle (<10°), in combination with nanoparticle reinforcement, diminishes the propensity for organic fouling by 50%. This extends the chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by an impressive 40%.
