Farming applications
Water plays an essential role in ensuring the health and optimal performance of livestock such as cattle, chickens, sheep, and pigs. It is not just the quantity but the quality of water that influences the desired growth and productivity of these animals.
Farms have diverse sources of water, including wells, civil water networks, and occasionally rivers and other surface sources.
Except for water from civil networks (which contain free chlorine), other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven highly effective in mitigating these issues. Consequently, farm water must undergo technological treatment to remove harmful substances, ensuring the safety and health of livestock.

Proshare Pioneering Advances in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our expert team has ingeniously crafted the next generation of reverse osmosis membranes, harnessing cutting-edge polymer interface nano-self-assembly. This innovation triumphantly addresses the traditional challenges of reverse osmosis membrane development through two transformative breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has impressively minimized the separation layer's thickness, rendering it at least three times thinner than the conventional polyamide thin films (historically capped at 100 nm). This landmark achievement dramatically boosts water flux, culminating in a remarkable leap in permeability.
Superior Performance Enhancements: By integrating nanoparticles and tailored hydrophilic polymers, we've ushered in significant improvements in hydrophilicity, anti-fouling prowess, durability, and oxidation resistance of the membrane.
In comparison to standard polyamide reverse osmosis membranes, Proshare's groundbreaking innovation shatters benchmarks in four pivotal areas:
Self-Assembled Nanocomposite Films Mastery
Through the synergy of nano-scale precision control and nano-doping modification, we achieve the creation of ultra-thin, highly ordered separation layers using polymer interface nanotechnology, overcoming the constraints of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Unparalleled Water Flux and Energy Efficiency
Refining the layer-by-layer self-assembly process, we meticulously control functional layer thickness, realizing a 3x reduction compared to traditional membranes. This advancement culminates in over 3x enhanced water flux and 30% decreased energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Transitioning beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast extraordinary oxidation resistance (withstanding up to 10 ppm chlorine exposure) and impressive pH stability (remaining stable across a pH range of 1-12).
