Farming Applications
Water quality is crucial for maintaining animal health and optimizing their productivity. This holds true for cattle, chickens, sheep, and pigs, where both the quantity and quality of water significantly influence their growth and performance.
Water for farms can originate from various sources, such as wells, civil water networks, and to a lesser extent, rivers and surface sources.
Apart from civil networks (containing free chlorine), other sources often harbor high levels of dissolved solids, suspended particles, and pathogens. Hence, reverse osmosis technology emerges as the most effective solution for mitigating these contaminants, ensuring the water used on farms is treated to remove substances detrimental to animal health.
