Farming Applications
Water is indispensable for ensuring animal well-being and optimizing their productive performance, whether they be cattle, chickens, sheep, or pigs. It's not just the volume but also the quality of water that significantly influences the desired growth outcomes in animals.
Water utilized in farming can originate from a diverse array of sources, including water wells, civil water networks, and, though to a lesser degree, rivers and other surface sources.
While civil networks typically contain free chlorine, other sources often exhibit high concentrations of dissolved solids, suspended particles, and pathogens. Consequently, reverse osmosis technology emerges as the preeminent solution for mitigating these adverse effects, ensuring that farm water undergoes the necessary technological treatments to eliminate harmful substances, safeguarding animal health.
