Agricultural Applications
Water is indispensable for ensuring animal health (e.g., cattle, chickens, sheep, pigs) and optimizing their productive performance. Not only does the quantity of water impact animal growth, but its quality is equally critical.
Farm water can stem from a variety of sources, including wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
With the exception of water from civil networks (which contains free chlorine), other sources typically possess elevated levels of dissolved and suspended solids, as well as pathogens. Therefore, reverse osmosis technology has emerged as the most effective method to mitigate these adverse effects. Contaminated farm water requires technological treatment to reduce harmful substances for the animals.
