Farming Applications

Water is crucial for ensuring the well-being of farm animals, such as cattle, chickens, sheep, and pigs, and achieving optimal productivity. Both the quantity and quality of water significantly affect the desired growth and health of the animals.
Water used on farms originates from various sources, including water wells, civil water networks, and occasionally, rivers and other surface sources.
Aside from water from civil networks that contain free chlorine, other water sources often present high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology is recognized as the most effective method to mitigate these negative effects. Therefore, contaminated water utilized on farms should undergo advanced technological treatment to remove harmful substances, ensuring the health and safety of the animals.
