Farming Applications

Water is fundamental to ensuring the wellness and optimal productivity of farm animals, such as cattle, chickens, sheep, and pigs. Beyond just quantity, the quality of water plays a critical role in achieving the desired growth and performance in animals.
On farms, water is sourced from diverse origins, such as water wells, municipal water networks, and, to some extent, rivers and other surface sources.
Excluding municipally supplied water (which contains free chlorine), other sources often harbor high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be an exceptionally effective method for mitigating these adverse effects. It is essential that contaminated water used on farms undergo advanced technological treatment to minimize harmful substances for animal health.

Successful Cases Reference

Our Advantages

Proshare Revolutionary Breakthrough in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our brilliant team has shattered barriers in reverse osmosis innovation by ingeniously developing a cutting-edge generation of membranes. By harnessing polymer interface nano-self-assembly technology, we have triumphed over conventional membrane challenges with two monumental advancements:
Ultra-Thin Separation Layer: Utilizing the groundbreaking potential of polymer interface nanotechnology, our team has remarkably minimized the separation layer thickness to less than one-third of the traditional polyamide thin film's thickness (previously confined to 100 nm). This pioneering feat dramatically boosts water flux, leading to an extraordinary surge in permeability.
Enhanced Performance: Our innovative infusion of nanoparticles and specialized hydrophilic polymers has led to unprecedented strides in enhancing the membrane's hydrophilicity, superior anti-fouling properties, remarkable durability, and exceptional oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's trailblazing innovation shines with breakthroughs across four vital areas:
Self-Assembled Nanocomposite Films
The synergy of nano-scale precision and nano-doping modification allows for the crafting of ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This transformative method transcends the barriers of traditional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
With the perfection of the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, achieving a reduction to one-third compared to conventional membranes, culminating in >3x superior water flux and a 30% decrease in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Transcending the limits of polyamide, our team employs state-of-the-art hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials boast unparalleled oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH endurance (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) reinforced with nanoparticles significantly diminishes organic fouling by 50%, doubling the duration between chemical cleanings from 3 to 6 months and slashing maintenance costs by 40%.
