Farming Applications
Water is a fundamental component in ensuring the health and productivity of livestock, including cattle, chickens, sheep, and pigs. The performance and growth of animals are influenced by both the quantity and quality of water they receive.
Farms utilize various water sources, such as water wells, municipal water networks, and to a lesser extent, rivers and other surface water sources.
Except for water from municipal networks that contain free chlorine, other sources often contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these adverse effects. Therefore, contaminated water used on farms should undergo technological treatment to reduce substances potentially harmful to livestock.

Proshare Pioneering a Revolutionary Leap in Reverse Osmosis Membrane Technology
Proshare Our dynamic team has triumphantly crafted a groundbreaking new generation of reverse osmosis membranes, utilizing cutting-edge polymer interface nano-self-assembly technology. This remarkable innovation triumphs over the traditional limitations faced by conventional reverse osmosis membranes through two pivotal advancements:
Ultra-Thin Separation Layer Mastery: Leveraging the power of polymer interface nanotechnology, our team has ingeniously reduced the separation layer's thickness to a remarkable level, making it at least three times thinner than the conventional polyamide thin films that were previously restricted to 100 nm. This monumental breakthrough supercharges the water flux, culminating in a dramatic enhancement in permeability.
Heightened Performance and Durability: By introducing pioneering nanoparticles alongside specialized hydrophilic polymers, we have achieved extraordinary advancements in the membrane's hydrophilicity, anti-fouling strength, durability, and oxidation resistance.
When compared to the traditional polyamide reverse osmosis membranes, Proshare's state-of-the-art innovation showcases breakthroughs in four fundamental aspects:
Self-Assembled Nanocomposite Films of Superior Precision
By integrating nano-scale precision control with nano-doping modification, we have enabled the creation of ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This sophisticated approach surmounts the limitations of conventional polyamide membranes, notably in aspects of thickness uniformity and material diversity.
Enhanced Water Flux Coupled with Superior Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we have precisely controlled the functional layer's thickness, achieving a phenomenal reduction of 3 times compared to traditional membranes. This leads to over 3 times higher water flux as well as a 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Unmatched Chemical Stability
Surpassing the confines of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These exceptional materials exhibit extraordinary resistance to oxidation (withstanding exposure to 10 ppm chlorine) and impressive pH tolerance (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, dramatically reduces the propensity for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months and significantly reduces maintenance costs by 40%.
