Farming Applications
In farming, water quality is of paramount importance to ensure the health and peak productivity of animals such as cattle, chickens, sheep, and pigs. Beyond mere quantity, water quality plays a pivotal role in achieving the desired growth and optimal performance of these animals.
Farm water can be sourced from a variety of origins, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Apart from water from civil networks (which contains free chlorine), other sources often present high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has emerged as the most effective solution to mitigate these adverse effects. Consequently, contaminated farm water must undergo technological treatment to eradicate substances detrimental to animal welfare.
