Farming applications
Water quality is vital for ensuring optimal animal health and productivity on farms, be it cattle, chickens, sheep, or pigs. Not just the quantity, but the quality of water significantly influences animal growth and performance.
Farms utilize water from diverse sources like wells, civil water networks, and, to a lesser extent, rivers and other superficial sources. Ensuring high water quality is paramount.
Non-civil network water sources often contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these negative effects, ensuring that water used on farms undergoes necessary technological treatment to eliminate harmful substances for animal health.

Proshare Revolutionizing the Future: Our Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has pioneered a transformative approach to reverse osmosis membranes, employing polymer interface nano-self-assembly technology. This innovation decisively surpasses traditional membrane limitations with two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging polymer interface nanotechnology, our team has achieved a separation layer that is at least three times thinner than conventional polyamide thin films (previously restricted to 100 nm). This remarkable enhancement dramatically boosts water flux, offering a significant leap in permeability.
Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we have unlocked extraordinary advancements in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation shines in four crucial areas:
Self-Assembled Nanocomposite Films
Our integration of nano-scale precision control and nano-doping modification allows the fabrication of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This technique effectively addresses the challenges of thickness uniformity and material diversity inherent in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we precisely manage functional layer thickness, achieving a threefold reduction compared to traditional membranes. This advancement delivers >3x the water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Going beyond polyamide, we employ leading-edge hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials demonstrate remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (stability maintained across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°) fortified with nanoparticle reinforcement significantly reduces organic fouling by 50%, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance costs by 40%.
