Agricultural Applications
Water is a critical factor in ensuring the optimal health and performance of livestock such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water significantly affect the animals' growth and productivity.
Water for agricultural use can originate from a multitude of sources, such as water wells, municipal water networks, and occasionally from rivers and other surface sources.
Apart from municipal networks (which contain free chlorine), other water sources often possess high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proved to be the most effective method to mitigate these harmful effects, ensuring that farm water undergoes comprehensive treatment to remove detrimental substances that can affect animal health.

Proshare Pioneering Breakthroughs in Advanced Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes, leveraging the revolutionary polymer interface nano-self-assembly technology. We've shattered the barriers of traditional membrane development with two monumental advancements:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our experts have remarkably minimized the separation layer thickness to an impressive three times thinner than the conventional polyamide thin films (previously constrained to 100 nm). This significant leap forward in technology tremendously boosts water flux, yielding a remarkable enhancement in permeability.
Unparalleled Enhanced Performance: The strategic introduction of nanoparticles and specialized hydrophilic polymers has catalyzed groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling properties, durability, and robust oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's innovation stands out with breakthroughs in these four pivotal aspects:
Self-Assembled Nanocomposite Films
Through the sophisticated integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers with polymer interface nanotechnology, overcoming the uniformity and diversity limitations of conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we achieve a functional layer thickness that is precisely controlled and reduced by threefold compared to traditional membranes. This results in an impressive >3x higher water flux accompanied by a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Breaking free from polyamide constraints, our team employs advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials show outstanding resistance to oxidation (capable of withstanding chlorine exposure up to 10 ppm) and remarkable pH tolerance (stable within a pH range of 1-12).
Revolutionary Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle <10°) combined with nanoparticle reinforcement significantly diminishes organic fouling by 50%, thereby extending chemical cleaning cycles from 3 to 6 months and cutting maintenance expenses by a notable 40%
