Farming applications
Water is an irreplaceable resource ensuring the health of animals like cattle, chickens, sheep, and pigs, and it is crucial for optimizing their productivity. However, not only the quantity but also the quality of water significantly influences the desired growth and performance of these animals.
Farm water often originates from diverse sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding civil water networks containing free chlorine, other sources typically present high concentrations of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology has proven to be the most efficient method for mitigating these adverse effects. Contaminated farm water must undergo technological treatment to diminish harmful substances, ensuring the well-being of animals.

Proshare Team's Groundbreaking Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully developed a cutting-edge generation of reverse osmosis membranes, pioneering the future of filtration with polymer interface nano-self-assembly technology. Through two monumental advancements, we have overcome the traditional barriers that limited reverse osmosis membrane development:
Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to a strikingly minimal level, achieving a layer that is at least three times thinner than the conventional polyamide thin film (historically constrained to 100 nm). This significant leap forward dramatically enhances water flux, resulting in a substantial increase in permeability.
Enhanced Performance: Through the introduction of sophisticated nanoparticles and specialized hydrophilic polymers, we have unlocked groundbreaking enhancements in the membrane's hydrophilicity, superior anti-fouling capability, robust durability, and unparalleled oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's innovation reveals transformative breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control with nano-doping modification, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This cutting-edge approach surpasses the conventional limitations of polyamide membranes in both thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This innovation culminates in >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Exceptional Chemical Stability
Moving beyond traditional polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) combined with ceramic-organic hybrids, showcasing extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within a 1-12 pH range).
