Farming applications

Water quality is crucial for ensuring the health and optimal performance of livestock such as cattle, chickens, sheep, and pigs. Not only the quantity but also the quality of water significantly impacts growth and productivity.
Farm water is sourced from various origins, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding chlorinated civil network water, other sources often contain high levels of dissolved solids and pathogens. Reverse osmosis technology has proven to be the most effective method for reducing these harmful elements. Therefore, contaminated farm water should undergo technological treatment to minimize substances harmful to animals.

Successful Cases Reference

Proshare's Exceptional PSI MEMBRANE World-class Desalination RO Membrane Pioneering Desalination Solutions for Elite Cruise Ships
The prestigious utilization of desalination membranes on international luxury cruise ships has traditionally been the realm of a select few renowned global brands. As the ships navigate through their voyages, the feed water's quality is subject to fluctuation in factors such as salinity and temperature. Consequently, these membranes must dynamically adjust to varying conditions, all the while delivering a consistent output of high-quality water to cater to the demanding requirements of ocean-bound vessels.
Exhibiting unrivaled performance, the PSI MEMBRANE Pro-HR-SW seawater desalination membranes excelled in both desalination efficacy and consistent water output. The water quality achieved by these membranes surpassed the rigorous standards set by luxury cruise ships.
This phenomenal achievement prompted the replacement of desalination membranes on three additional cruise liners. Proshare's landmark success in this endeavor marks it as the pioneering national brand to secure international luxury cruise ship contracts for desalination RO membranes.

Our Advantages

Proshare Team's Revolutionary Advancement in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully crafted a new era of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional membrane development by delivering two pivotal enhancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, we have achieved a remarkable reduction in the separation layer's thickness, rendering it at least three times thinner than the conventional polyamide thin film (which was previously constrained to 100 nm). This extraordinary leap forward significantly boosts water flux and achieves a profound improvement in permeability.
Enhanced Performance: By introducing nanoparticles alongside specialized hydrophilic polymers, we have pioneered groundbreaking advancements that remarkably enhance the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's innovation unveils breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control with nano-doping modification, we craft ultra-thin, impeccably ordered separation layers via polymer interface nanotechnology. This novel approach surmounts the limitations of traditional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing our layer-by-layer self-assembly process, we expertly manage functional layer thickness, achieving a threefold reduction over traditional membranes. This innovation leads to over three times higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond traditional polyamide, our team employs cutting-edge hydrophilic polymers, including modified polysulfones and ceramic-organic hybrids. These materials boast remarkable oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (remaining stable within a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle of <10°), enhanced by nanoparticle reinforcement, dramatically reduces the propensity for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 to 6 months and cuts maintenance costs by an impressive 40%.
