Farming applications

Water is vital to ensuring the health and performance of animals such as cattle, chickens, sheep, and pigs. It is not just the quantity but the quality of water that influences optimal growth and productivity.
Farm water can originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and surface sources.
Other than civil network water which contains free chlorine, other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these negative effects. Therefore, farm water should undergo technological treatment to remove substances harmful to animals.

Our Advantages

Proshare: Pioneers of Innovation Revolutionary Leap in Reverse Osmosis Membrane Innovation
Proshare: Leader in Membrane Technology Our dedicated team has embark on an innovative journey to develop a cutting-edge generation of reverse osmosis membranes. Utilizing state-of-the-art polymer interface nano-self-assembly technology, we've shattered the barriers of traditional membrane concepts through two groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has remarkably thinned the separation layer to one-third of the thickness of conventional polyamide films (previously limited to 100 nm). This bold innovation enhances water flux, delivering remarkable improvements in water permeability.
Unmatched Performance Enhancement: The infusion of nanoparticles and specialized hydrophilic polymers heralds unprecedented progress in boosting the membrane's hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
In comparison with standard polyamide reverse osmosis membranes, Proshare'sinnovations signify breakthroughs across four critical domains:
Pioneering Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with innovative nano-doping, we craft ultra-thin and meticulously ordered separation layers using cutting-edge polymer interface nanotechnology. This method transcends the constraints of traditional polyamide membranes in terms of thickness uniformity and material versatility.
Superior Water Flux and Energy Optimization
Through refined layer-by-layer self-assembly processes, we meticulously control the thickness of the functional layer, achieving a significant 3x reduction relative to traditional membranes. This precision engineering results in more than 3x higher water flux, alongside a 30% reduction in energy consumption,enhancing efficiency dramatically.
Innovative Polymer Materials with Unmatched Chemical Stability
Beyond conventional polyamides, we harness advanced hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These avant-garde materials showcase exceptional resistance to oxidation, withstanding exposure to 10 ppm chlorine and, demonstrating pH resilience, stable within a broad pH range of 1-12.
Sophisticated Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface (with a contact angle <10°), augmented by nanoparticle fortification, reduces organic fouling potential by 50%. This leads to an extension of chemical cleaning cycles from 3 to 6 months, while cutting maintenance costs by 40%.
