Farming applications

Water is vital for ensuring animal health and achieving optimal productivity in farming applications. However, it's not just the quantity, but the quality of water that influences the desired growth and performance of livestock such as cattle, chickens, sheep, and pigs.
The water utilized in farms may originate from various sources, including water wells, civil water networks, and occasionally from rivers and other surface sources.
Other than water from civil networks (which contain free chlorine), alternative sources often have high concentrations of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology emerges as the most efficient means to mitigate these negative effects. Farm water, especially if contaminated, requires advanced technological treatment to eliminate harmful substances, ensuring animal well-being.
