Palanisamy Great comment. I have been working on water quality with farmers and if I would add a comment about the solution, it would be treating the water hardness beforehand. To reduce the water hardness, you may use reverse osmosis or an ion exchange system. Do not use ion-exchange if the water is already high in sodium unless using potassium chloride instead of sodium chloride. Acidification (for example citric acid) can be used to dissolve scale caused by hardness.
