Farming applications

Water is a vital resource in maintaining animal health (e.g., cattle, chickens, sheep, pigs) and achieving optimal animal performance. It's not just the quantity but also the superior quality of water that can significantly impact desired growth outcomes.
Farms utilize water from diverse origins, such as water wells, civil water networks, and to a lesser degree, rivers and other surface sources.
Excluding civil network water (which contains free chlorine), other sources typically possess high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology has proven to be the most effective solution to mitigate these adverse effects, ensuring that contaminated farm water undergoes necessary technological treatment to decrease substances harmful to animal health.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our groundbreaking Proshare team has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes. Utilizing the cutting-edge polymer interface nano-self-assembly technology, we have shattered the conventional boundaries of reverse osmosis membrane development with two transformative breakthroughs:
Ultra-Thin Separation Layer: Harnessing the power of advanced polymer interface nanotechnology, our team has remarkably reduced the thickness of the separation layer to an ultra-fine dimension, at least three times thinner than the traditional polyamide thin film, which was previously constrained to 100 nm. This monumental progress drastically enhances water flux, delivering a remarkable leap in permeability and efficiency.
Enhanced Performance: Through the innovative incorporation of nanoparticles and specialized hydrophilic polymers, we have achieved groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases pioneering advancements in four essential areas:
Self-Assembled Nanocomposite Films
By masterfully integrating nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers using our polymer interface nanotechnology. This sophisticated approach triumphs over the conventional polyamide membranes' limitations in thickness uniformity and material diversity, setting a new standard in the industry.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control of functional layer thickness, accomplishing a remarkable 3x reduction compared to traditional membranes. This innovation results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking the boundaries of traditional polyamide, we utilize state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These innovative materials exhibit extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (stable across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, reinforced with nanoparticles, dramatically reduces organic fouling by 50%, extending chemical cleaning cycles from 3 to 6 months, and slashing maintenance costs by 40%.
