1. To guarantee optimal performance, the permeate flow rate and stabilized salt rejection are based on meticulously tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before any hot water disinfection.
2. Please bear in mind, the variation range of permeate flow is +/-15%, and the ultimate water yield may encounter additional fluctuations due to
the exigencies of the heat treatment process involved.

Agricultural Applications
Ensuring optimal animal health and productivity is critically dependent not only on the availability but also on the exceptional quality of water for animals such as cattle, chickens, sheep, and pigs. Superior water quality plays a pivotal role in fostering desired growth and maximizing animal performance.
Farm water sources are diverse, ranging from water wells, civic water networks, to rivers and other surface sources, each with unique characteristics.
Apart from chlorine-treated civic network water, other sources often contain high levels of dissolved and suspended solids and pathogens. Hence, reverse osmosis technology emerges as the most effective solution to mitigate these contaminants. For farm water, particularly from non-civic sources, technological treatment is essential to reduce harmful substances, safeguarding the health and welfare of the animals.
