Farming applications

Water is a critical component to ensure the health and vitality of farm animals (including cattle, chickens, sheep, and pigs), thereby enhancing optimal animal performance. However, the desired growth of these animals is not merely influenced by the quantity but also by the quality of the water they consume.
In farms, water is sourced from a variety of channels, including water wells, civil water networks, and occasionally from rivers and other superficial sources.
Except for water from civil networks, which contains free chlorine, other sources typically exhibit high concentrations of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology emerges as the most effective solution to mitigate these adverse effects. Contaminated farm water must undergo technological treatment to remove harmful substances and ensure safety for animal consumption.
