Farming Applications
In farming, water quality is critical to guaranteeing the health and peak productivity of animals such as cattle, chickens, sheep, and pigs. Beyond just quantity, the quality of water directly affects the optimal growth and performance of these animals.
Farm water may derive from diverse sources like water wells, civil water networks, and to a lesser degree, rivers and other surface sources.
Besides civil network water (which includes free chlorine), other sources often contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective method to combat these challenges. Consequently, contaminated farm water requires advanced technological treatment to remove harmful substances that could jeopardize animal health.
