Farming Applications
Water is a critical component in ensuring the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Achieving peak animal performance is influenced not only by the quantity but also by the quality of water provided.
Farm water sources can be varied, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. It is essential to ensure water quality for optimal farm operations.
Excluding civil network water (which contains free chlorine), other sources often harbor high concentrations of dissolved and suspended solids, along with pathogens. Reverse osmosis technology has proven to be the most effective solution for mitigating these adverse effects. To protect animal health, contaminated farm water must undergo advanced technological treatment to eliminate harmful substances.
