Farming applications
Water is a vital component for ensuring the well-being of livestock, such as cattle, chickens, sheep, and pigs, and optimizing their productive performance. Not only the quantity but also the quality of water plays a pivotal role in promoting the desired growth of the animals.
Water used on farms can originate from diverse sources, including water wells, municipal water networks, and, to a lesser degree, rivers and other surface sources.
Aside from water from municipal networks (which contains free chlorine), other sources typically possess high concentrations of dissolved solids, suspended particles, and pathogens. Consequently, reverse osmosis technology has proven to be the most effective in mitigating these adverse effects. To protect animal health, contaminated farm water must undergo technological treatment to reduce harmful substances.
