Using an NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), and an RO membrane (2000ppm NaCl solution,

1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection process.

2. The permeate flow variation range is +/-15%, and the final water yield may experience additional fluctuations due to

the heat treatment process, ensuring optimal performance.

Farming applications

Water is crucial to ensuring the health and optimal productivity of livestock such as cattle, chickens, sheep, and pigs. It's not only the quantity but the quality of water that affects animal growth, necessitating high standards of water quality on farms.
Farm water can originate from multiple sources, including water wells, civil water networks, and to a lesser extent, rivers and surface water sources. Ensuring the highest water quality is key to supporting farm operations.
Water sourced from civil networks often contains free chlorine, while other sources may have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these adverse effects. Contaminated farm water should be treated using advanced technologies to remove harmful substances, safeguarding animal health and productivity.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has innovatively developed a revolutionary generation of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This pioneering approach triumphs over the challenges faced by traditional reverse osmosis membranes through two pivotal advancements:
Ultra-Thin Separation Layer: With the expertise of polymer interface nanotechnology, our team has remarkably reduced the separation layer thickness to an unprecedented level-at least three times thinner than the conventional polyamide thin films, which were restricted to a thickness of 100 nm. This innovation substantially elevates water flux, leading to a remarkable boost in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has resulted in groundbreaking strides in enhancing the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation illustrates breakthroughs in four essential domains:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we have mastered the art of creating ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This method surpasses the conventional polyamide membranes' limitations regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This advancement results in >3x higher water flux, and a 30% reduction in energy consumption,making our solution both powerful and eco-friendly.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from the limitations of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials display extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a broad pH range of 1-12).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) and nanoparticle reinforcement, we successfully reduce organic fouling propensity by 50%, effectively extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by an impressive 40%.
