Farming Applications

Water's critical role in ensuring animal health (for instance, cattle, chickens, sheep, pigs) cannot be overstated, as it significantly impacts their productive performance. Both the quantity and the quality of water are pivotal for achieving desired growth outcomes.
Farm water sources are diverse, ranging from wells to civil water networks, and occasionally from rivers and other surface sources.
With the exception of water from civil networks, which contain free chlorine, other sources typically present a high concentration of dissolved and suspended solids and pathogens. Reverse osmosis technology has thus proven to be the most efficient method to mitigate these adverse effects, ensuring that farm water undergoes rigorous technological treatment to reduce harmful substances for the animals.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our groundbreaking team has achieved remarkable innovations by developing a cutting-edge generation of reverse osmosis membranes. Leveraging the sophisticated polymer interface nano-self-assembly technology, we have successfully transcended the conventional boundaries of traditional reverse osmosis membrane production, marked by two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing polymer interface nanotechnology, our team has ingeniously crafted a separation layer at least threefold thinner than the traditional 100 nm polyamide thin film. This pivotal advancement dramatically enhances water flux, delivering a remarkable improvement in permeability.
Enhanced Performance: By integrating nanoparticles along with specialized hydrophilic polymers, we have ushered in groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have engineered ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This strategy triumphs over the challenges of conventional polyamide membranes, achieving unparalleled thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we maintain precise control over the functional layer thickness, achieving a stunning 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
Surpassing the limitations of polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (demonstrating stability across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface (with a contact angle of less than 10°) combined with nanoparticle reinforcement significantly reduces the tendency for organic fouling by 50%, extending the chemical cleaning cycle from 3 to 6 months and slashing maintenance costs by 40%.
