1. To guarantee peak performance, the permeate flow rate and salt rejection stability are meticulously determined under strictly controlled standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection.
2. Please be reminded that the variation range of permeate flow is +/-15%, and the ultimate water yield may vary due to
the intricacies of the heat treatment process.

Ensuring top-notch water quality is essential for optimal animal health and productivity (across cattle, chickens, sheep, and pigs). High-quality water is a critical factor influencing desired growth and maximizing the performance of these animals.
Farm water sources are diverse, drawing from water wells, civil water networks, and, on occasion, rivers and other surface sources, each with its own unique properties.
Apart from chlorine-treated civil network water, other sources often carry elevated levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as the leading solution for mitigating such contaminants. It's essential for farm water, particularly from non-civil origins, to undergo advanced treatment to reduce harmful substances, ensuring the health and safety of livestock.
