Farming Applications
Water is crucial to ensure the well-being of livestock, such as cattle, chickens, sheep, and pigs, fostering optimal animal performance. The water quality, alongside its quantity, significantly influences the desired growth and productivity of the animals.
Farm water sources can vary greatly, originating from water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding civil network water, which contains free chlorine, other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective solution for mitigating these negative effects. Contaminated farm water requires sophisticated treatment to remove harmful substances, safeguarding animal health and productivity.
