Farming applications

Water is crucial for ensuring optimal animal health and performance, such as cattle, chickens, sheep, and pigs. While water quantity is important, its quality is equally vital to fostering desired animal growth.
Farm water sources include water wells, civil water networks, and occasionally rivers and surface water. However, these sources often contain high levels of dissolved solids and pathogens.
Water from non-civil networks, often laden with dissolved and suspended solids and pathogens, necessitates reverse osmosis treatment-the most effective technology for counteracting harmful contaminants in farm water, safeguarding animal health.

Our Advantages

Proshare Pioneering Breakthroughs in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted an advanced generation of reverse osmosis membranes, leveraging revolutionary polymer interface nano-self-assembly technology. We have transcended the traditional barriers in membrane development with two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has achieved a remarkable reduction in separation layer thickness, now at least three times thinner than the conventional 100 nm polyamide films. This innovation dramatically boosts water flux, resulting in unprecedented permeability improvements.
Unmatched Performance Enhancement: Through the strategic infusion of nanoparticles and state-of-the-art hydrophilic polymers, we have set new standards in membrane hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's remarkable innovation showcases transformative breakthroughs across four critical domains:
Ingenious Self-Assembled Nanocomposite Films
Our precise nano-scale control and innovative nano-doping modification have facilitated the development of ultra-thin, highly structured separation layers. These layers are crafted through polymer interface nanotechnology, overcoming conventional polyamide membrane limitations in uniformity and material variety.
Superior Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly technique, we accurately manage the functional layer's thickness, achieving a remarkable 3x reduction compared to standard membranes. This leads to >3x enhancement in water flux and 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Going beyond polyamide, we employ advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials possess remarkable resistance to oxidation (endure 10 ppm chlorine exposure) and tolerance to a wide pH range (remaining stable in pH levels from 1 to 12).
Cutting-Edge Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle less than 10°, bolstered by nanoparticle reinforcement, reduces organic fouling by 50%. This extends chemical cleaning intervals from 3 to 6 months and slashes maintenance costs by 40%.
