Farming applications
Water is indispensable in ensuring the vitality and optimal productivity of farm animals such as cattle, chickens, sheep, and pigs. Not only does the volume of water play a critical role, but so does its quality, which significantly impacts the animals' growth and productivity.
Farms draw water from a multitude of sources, including water wells, municipal water networks, and to a lesser degree, rivers and other surface sources.
Aside from municipal water (which contains free chlorine), these alternative sources often exhibit high concentrations of dissolved solids, suspended particles, and potential pathogens. Reverse osmosis technology emerges as the preeminent solution to mitigate these adverse effects, necessitating technological intervention to purify the water used in farms, thereby safeguarding animal health and productivity.

Proshare Our Pioneering Achievement in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes, capitalizing on polymer interface nano-self-assembly technology. This innovation transcends the traditional boundaries of reverse osmosis membrane development through two pivotal breakthroughs:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has successfully diminished the thickness of the separation layer to at least one-third the thickness of traditional polyamide thin films, previously constrained to 100 nm. This remarkable achievement dramatically enhances water flux, resulting in a significant leap in permeability.
Enhanced Performance: Through the integration of nanoparticles and specialized hydrophilic polymers, we've ushered in transformative advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation exemplifies groundbreaking progress in four critical dimensions:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modification, we're crafting ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This technique transcends the limitations of conventional polyamide membranes in both thickness uniformity and material diversity.
Enhanced Water Flux and Superior Energy Efficiency
By fine-tuning the layer-by-layer self-assembly process, we've precisely controlled the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. Consequently, this innovation results in over 3x augmented water flux and a 30% reduction in energy consumption.
Novel Polymer Materials Featuring Superior Chemical Stability
Beyond polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These advanced materials boast exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a 1-12 pH range).
Revolutionary Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, dramatically reduces the propensity for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, slashing maintenance costs by 40%.
