Farming applications
Water is crucial in maintaining animal health and optimizing productivity in farming environments. Both the quantity and quality of water play vital roles in the growth and performance of livestock such as cattle, chickens, sheep, and pigs, emphasizing the need for superior water management solutions.
Farm water can originate from a variety of sources, including water wells, municipal water networks, and to a lesser extent, rivers and other surface sources. Each source demands careful management to ensure water quality remains uncompromised and suitable for farm use.
Aside from municipal water networks, which typically contain free chlorine, other sources often harbor high levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis has proven to be the most effective technology in mitigating these adverse effects. It ensures that water used in farms undergoes crucial technological treatment to remove harmful substances, safeguarding animal health and productivity.
Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship

Proshare Trailblazing Innovations in Reverse Osmosis Membrane Technology by Our Expert Team
Proshare Our talented team has ingeniously crafted cutting-edge reverse osmosis membranes utilizing polymer interface nano-self-assembly technology. This innovation marks a significant departure from conventional methods through two remarkable breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, we have achieved an unprecedented reduction in separation layer thickness to a mere fraction-three times thinner than the traditional 100 nm polyamide thin film. This extraordinary advancement propels water flux to new heights, offering a remarkable boost in permeability.
Superior Performance Enhancement: By embedding nanoparticles and incorporating specialized hydrophilic polymers, we've unlocked transformative improvements in the membrane's hydrophilicity, anti-fouling prowess, robustness, and resistance to oxidation.
In contrast with traditional polyamide reverse osmosis membranes, Prosharepioneers key breakthroughs across four critical dimensions:
Innovative Self-Assembled Nanocomposite Films
Our mastery of nano-level precision control and nano-doping modification leads to the formation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This method triumphs over the conventional polyamide membrane's limitations in uniformity and material diversity.
Enhanced Water Flux Coupled with Unparalleled Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over functional layer thickness, slashing it by a factor of three compared to traditional membranes. This innovation results in a water flux exceeding threefold while consuming 30% less energy.
Pioneering Polymer Materials with Exceptional Chemical Stability
Going beyond the standard polyamide, our team leverages avant-garde hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These materials shine with remarkable resistance to oxidation (withstanding exposure up to 10 ppm chlorine) and broad pH tolerance (retaining stability within a 1-12 pH range).
Ingenious Anti-Fouling Surface Engineering
