Farming applications
In farming, water is crucial for ensuring the health and productivity of livestock such as cattle, chickens, sheep, and pigs. It's not just the quantity of water that matters, but also the quality, which significantly impacts the animals' growth and performance.
Farm water can originate from various sources like wells, civil water networks, and occasionally from rivers or other surface sources.
Aside from water from civil networks, which contains free chlorine, other sources often have high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most efficient method for mitigating these negative effects, ensuring contaminated farm water undergoes thorough technological treatment to eliminate harmful substances.

Proshare Revolutionary Leap: Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a new generation of reverse osmosis membranes, utilizing cutting-edge polymer interface nano-self-assembly technology. This breakthrough shatters the boundaries of traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging polymer interface nanotechnology, we've achieved an unprecedented reduction in the separation layer's thickness, now at least three times thinner than the conventional polyamide thin films, which were previously limited to 100 nm. This triumph dramatically amplifies water flux, offering a remarkable boost in permeability.
Enhanced Performance: By incorporating nanoparticles and expertly crafted hydrophilic polymers, we've reached groundbreaking improvements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modifications, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This groundbreaking method surpasses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
With precise optimization of the layer-by-layer self-assembly process, we've precisely controlled the functional layer thickness, achieving 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
Venturing beyond polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials demonstrate outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, dramatically reduces the propensity for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by 40%.
