Farming Applications
To ensure the pinnacle of animal health and productivity (spanning cattle, chickens, sheep, and pigs), the excellence of water quality is as pivotal as its availability. Premium water quality is instrumental in propelling desired growth and optimizing animal performance.
Farm water sources can vary greatly, originating from water wells, civil water networks, and at times from rivers and additional surface sources, each harboring unique qualities.
Besides the chlorine-treated civil network water, alternative sources frequently possess elevated levels of dissolved and suspended solids alongside pathogenic elements. Thus, adopting reverse osmosis technology stands as the paramount approach to mitigate these impurities. It is imperative for farm water, particularly from non-civil origins, to undergo advanced technological treatment to eliminate harmful substances, safeguarding the animals' health and welfare.
