Farming applications

Water is a crucial component to ensure the optimal health of farm animals, such as cattle, chickens, sheep, and pigs, and to attain the peak performance of productive animals. The quality, alongside the quantity of water, plays a vital role in influencing the desired growth and health of the animals.
The water utilized on farms can originate from various sources, such as water wells, civil water networks, and occasionally from rivers and other surface water sources.
Apart from water from civil networks (which contains free chlorine), other sources typically possess high levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology has proven to be the most effective solution to diminish these adverse effects. Contaminated farm water should undergo advanced technological treatment to mitigate harmful substances and protect animal health.
