Farming Applications

Water plays a pivotal role in ensuring optimal animal health and productivity on farms, impacting livestock such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water significantly influence the growth and productivity of animals. Ensuring high-quality water is a prerequisite for achieving desired performance levels.
The water utilized on farms can originate from various sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources. Each source presents distinct characteristics that must be managed effectively.
Excluding civil network water (which contains free chlorine), other sources typically possess high levels of dissolved and suspended solids along with pathogens. Reverse osmosis technology has emerged as the most effective solution for mitigating these adverse effects. It ensures the harmful substances in contaminated farm water are significantly reduced, safeguarding animal health and optimizing growth.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has pioneered a revolutionary leap forward, crafting a new era of reverse osmosis membranes through the use of cutting-edge polymer interface nano-self-assembly technology, shattering the confines of conventional methodologies with two pivotal innovations:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, we have ingeniously minimized the separation layer's thickness to an impressive scale, achieving a remarkable reduction-three times thinner than the standard polyamide thin film, which was previously constrained to 100 nm. This monumental achievement supercharges water flux, dramatically boosting permeability.
Enhanced Performance: With the infusion of nanoparticles and unique hydrophilic polymers, we have attained phenomenal enhancements in the membrane's hydrophilicity, resistance to fouling, robustness, and protection against oxidation, setting new performance benchmarks.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation excels in four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control coupled with nano-doping enhancements, we craft ultra-thin, intricately structured separation layers with polymer interface nanotechnology. This strategy transcends the barriers of conventional polyamide membrane design, offering unmatched thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly technique allows for exacting control over the functional layer's thickness, achieving a remarkable 3x reduction versus traditional membranes. The result is an impressive >3x increase in water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond the realms of polyamide, we employ state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability in a pH range of 1-12).
Anti-Fouling Surface Engineering
Our cutting-edge superhydrophilic surface (contact angle <10°), fortified with nanoparticle reinforcements, effectively reduces organic fouling risk by 50%, doubling the interval for chemical cleaning cycles from 3 months to 6 months, thereby slashing maintenance costs by 40%.
