1. The permeate flow rate and stabilized salt rejection are based on these precise standard test conditions:
For NF membrane: 2000ppm MgSO4, 0.48 MPa, 25ºC, with a 15% recovery rate. For RO membrane: 2000ppm NaCl solution,
tested at 1.55 MPa, 25ºC, with a 15% recovery rate, all before undergoing any hot water disinfection.
2. The permeate flow variation range is +/-15%, and the final water yield may vary more due to
the intricacies of the heat treatment process.

Water quality is pivotal in ensuring optimal animal health and productivity (e.g., cattle, chickens, sheep, pigs). It's not just about quantity; high-quality water is crucial for achieving the desired growth and performance of farm animals.
Farm water can originate from diverse sources such as wells, civil water networks, and occasionally rivers or surface sources, each contributing uniquely to farm operations.
While civil network water contains free chlorine, other sources often bear high levels of dissolved solids and pathogens. Reverse osmosis technology, proven most effective, treats farm water to diminish these pollutants, safeguarding animal health against harmful substances.

Proshare Pioneering Breakthroughs in Next-Generation Reverse Osmosis Membrane Technology
Proshare The brilliant minds at Proshare have innovatively crafted a cutting-edge generation of reverse osmosis membranes. Using state-of-the-art polymer interface nano-self-assembly technology, they have triumphed over the traditional boundaries in membrane development through two monumental advancements:
Revolutionary Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to a third of that in conventional polyamide thin films (previously constrained to 100 nm). This significant leap forward enhances water flux dramatically, resulting in an unparalleled improvement in permeability.
Unmatched Enhanced Performance: By incorporating cutting-edge nanoparticles and distinctive hydrophilic polymers, we have achieved groundbreaking progress in elevating the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation stands out with breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
With a fusion of nano-scale precision control and nano-doping modification, we masterfully create ultra-thin, meticulously ordered separation layers. This is made possible through polymer interface nanotechnology, effectively overcoming conventional polyamide membranes' challenges in thickness uniformity and material diversity.
Enhanced Water Flux and Unprecedented Energy Efficiency
By refining the layer-by-layer self-assembly technique, we accurately control the functional layer thickness, showcasing a 3-fold reduction compared to standard membranes. This results in >3x superior water flux and a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Unsurpassed Chemical Stability
Breaking free from polyamide constraints, our team employs advanced hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These materials possess extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH versatility (remaining stable across a pH range of 1-12).
Innovative Anti-Fouling Surface Engineering
The synergy of a superhydrophilic surface (contact angle <10°) with nanoparticle reinforcement dramatically mitigates organic fouling propensity by 50%. This extends chemical cleaning intervals from 3 months to 6 months, while slashing maintenance costs by 40%
