In farming, water quality is crucial to ensure the optimal health and productivity of animals, including cattle, chickens, sheep, and pigs. It's not just the water quantity; the quality critically influences the growth and performance outcomes of these animals, making it a vital factor in farming success.
Farm water sources are diverse, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources, each presenting unique challenges and opportunities.
While civil network water often contains free chlorine, other water sources typically harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis stands out as the most effective method to counter these challenges. It's essential that contaminated farm water undergo technological treatment to remove harmful substances, ensuring the safety and health of livestock.
