Agricultural Applications
Water is vital to ensure the health and optimal productivity of farm animals such as cattle, chickens, sheep, and pigs. However, it is not just the quantity of water that is crucial; its quality also plays a significant role in achieving desired growth and productivity levels.
Farm water sources can vary greatly, originating from wells, civil water networks, and occasionally rivers or other surface water sources.
Excluding water from civil networks (which often contains free chlorine), these alternative sources typically have higher levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method in mitigating these harmful effects, ensuring the water used on farms is treated to reduce substances that could adversely affect animal health.
