Farming Applications
Water is a pivotal element in ensuring the well-being and optimal productivity of farm animals, such as cattle, chickens, sheep, and pigs. Both the quantity and the quality of water are crucial to achieving the desired growth and performance of these animals.
Farm water sources are diverse, originating from water wells, civil water networks, and occasionally from rivers and other superficial sources.
Excluding water from civil networks (which contain free chlorine), alternative sources often have high concentrations of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology has proven to be the most efficient method for mitigating the adverse effects of contaminated water. It's imperative that water used on farms undergo thorough technological treatment to reduce harmful substances and ensure the health and productivity of the animals.

Proshare The Team's Revolutionary Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a groundbreaking new generation of reverse osmosis membranes, utilizing state-of-the-art polymer interface nano-self-assembly technology. This innovative approach has shattered the constraints of traditional reverse osmosis membrane development through two remarkable advancements:
Ultra-Thin Separation Layer Mastery: Harnessing the power of polymer interface nanotechnology, our team has achieved a phenomenal reduction in separation layer thickness, creating a layer that is at least three times thinner than the conventional polyamide thin film, which was previously confined to 100 nm. This exceptional breakthrough dramatically boosts water flux, leading to a significant elevation in permeability.
Exemplary Enhanced Performance: The strategic incorporation of nanoparticles and specially formulated hydrophilic polymers has catalyzed groundbreaking advancements in membrane hydrophilicity, extraordinary anti-fouling capabilities, enhanced durability, and superior oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
The seamless integration of nano-scale precision control with nano-doping modification empowers the creation of ultra-thin, highly ordered separation layers using cutting-edge polymer interface nanotechnology. This sophisticated approach transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Superior Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, resulting in a remarkable 3x reduction compared to traditional membranes. This strategic advancement leads to more than 3x higher water flux and an impressive 30% reduction in energy consumption.
Advanced Polymer Materials with Exceptional Chemical Stability
Surpassing the capabilities of polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These avant-garde materials demonstrate remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and robust pH tolerance (exhibiting stability across a pH range of 1 to 12).
