Farming Applications
In farming, water quality stands as a cornerstone for ensuring the health and optimal productivity of animals such as cattle, chickens, sheep, and pigs. Beyond mere quantity, water quality profoundly influences the desired growth and performance of these animals.
Farm water originates from a myriad of sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface water sources.
Besides water from civil networks (which contains free chlorine), other sources generally harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most potent method to combat these challenges. Consequently, farm water that is contaminated necessitates technological treatment to eradicate harmful substances that may endanger the animals.
