Farming applications

Water is indispensable for ensuring the health and optimal performance of animals, such as cattle, chickens, sheep, and pigs. It's not just the quantity but the quality of water that is pivotal in influencing their growth and productivity.
Farms utilize water from diverse sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources, each impacting the quality of water available for agricultural use.
Excluding water from civil networks, which contains free chlorine, other sources often have high concentrations of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology stands out as the most effective solution for mitigating these negative impacts. Contaminated farm water requires technological treatment to reduce harmful substances, safeguarding animal health and ensuring optimal growth.

Our Advantages

Proshare Team's Pioneering Leap in Advanced Reverse Osmosis Membrane Technology
Proshare team has revolutionized the field by crafting a cutting-edge new generation of reverse osmosis membranes through polymer interface nano-self-assembly technology. By conquering the traditional reverse osmosis membrane's limitations, we've achieved two groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Through the strategic application of polymer interface nanotechnology, our team has expertly minimized the separation layer's thickness to a remarkable fraction of the traditional polyamide thin film (once confined to 100 nm). This landmark achievement exponentially boosts water flux, marking a significant leap in permeability.
Superior Enhanced Performance: By integrating nanoparticles and advanced hydrophilic polymers, we have unlocked unprecedented improvements in hydrophilicity, anti-fouling properties, longevity, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's ingenuity shines through breakthroughs in four remarkable domains:
Innovative Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification allows the formation of ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This innovative strategy transcends the common constraints of conventional polyamide membranes, notably in thickness consistency and material versatility.
Enhanced Water Flux and Unmatched Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, we've achieved impeccable control over functional layer thickness, shrinking it to a third of traditional membrane thickness. This innovation yields over 3x the water flux and a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Exceptional Chemical Stability
Beyond polyamide, our team embraces cutting-edge hydrophilic polymers, including modified polysulfones and ceramic-organic hybrids. These strategic materials showcase outstanding resistance to oxidation (capable of withstanding 10 ppm chlorine exposure) and tolerance to a wide pH spectrum (remaining stable across a pH range of 1-12).
Revolutionary Anti-Fouling Surface Engineering
The superhydrophilic surface (with a contact angle of less than 10°), bolstered by nanoparticle reinforcement, reduces organic fouling tendencies by an impressive 50%. This extends chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by 40%.
