Farming Applications
Water quality is paramount in farming to ensure the health and optimal productivity of animals such as cattle, chickens, sheep, and pigs. Beyond quantity, water quality significantly impacts the desired growth and performance of these animals.
Farm water can originate from various sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Apart from water from civil networks (which contains free chlorine), other sources typically present high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to counteract these adverse effects. Therefore, contaminated farm water must undergo technological treatment to eliminate substances that may harm the animals.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The innovative minds at Proshare have achieved a revolutionary leap in reverse osmosis membrane technology, harnessing the power of polymer interface nano-self-assembly to surpass traditional limitations through two groundbreaking advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has successfully reduced the separation layer thickness to an unprecedented level, at least threefold thinner than the conventional 100 nm polyamide thin film. This remarkable breakthrough significantly amplifies water flux and dramatically elevates permeability.
Enhanced Performance: Thanks to the strategic incorporation of nanoparticles and specialized hydrophilic polymers, we have achieved extraordinary improvements in hydrophilicity, anti-fouling capabilities, and membrane robustness. This innovation ensures unmatched durability and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation heralds breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control and nano-doping modifications, we establish ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This technique surpasses the traditional limits of polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely managed, achieving a threefold reduction compared to conventional membranes. The outcome is an impressive >3x higher water flux and 30% lower energy consumptionensuring eco-friendly and cost-effective performance.
Novel Polymer Materials with Superior Chemical Stability
Transitioning beyond polyamide, our team employs advanced hydrophilic polymers like modified polysulfones and ceramic-organic hybrids.
