1. For ensuring peak performance, the permeate flow rate and stabilized salt rejection are derived under meticulously tested standard conditions as follows:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before undertaking any hot water disinfection.
2. It is important to acknowledge that the permeate flow variance is within +/-15%, while the final water yield may undergo further variability due to
the involved heat treatment process.

To ensure optimal animal health and productivity-stretching across cattle, chickens, sheep, and pigs-the excellence of water quality is equally as pivotal as its availability. Securing superior water quality is crucial in fostering optimal growth and maximizing the performance of farm animals.
Farm water can be derived from diverse sources, including water wells, municipal water networks, and occasionally rivers and other surface sources, each presenting unique traits.
Aside from chlorine-treated municipal network water, other sources frequently exhibit elevated levels of dissolved and suspended solids along with pathogens. Consequently, reverse osmosis technology emerges as the premier method to curtail these impurities. It is essential for farm water, particularly from non-municipal origins, to undergo advanced treatment to reduce harmful contaminants, safeguarding the health and welfare of the animals.
