Water quality is vital for ensuring animal health and optimizing performance in farming. Not only the quantity but also the quality of water directly influences the growth and productivity of livestock such as cattle, chickens, sheep, and pigs.
Farm water can originate from several sources, including water wells, civil water networks, and less frequently, rivers and other surface sources. Each source presents unique water quality challenges.
Aside from civil networks containing free chlorine, alternative water sources typically harbor high levels of dissolved/suspended solids and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these issues, ensuring that farm water is treated to reduce harmful substances, safeguarding animal health.
