This analysis is not what we asked for. It shows only that anions of strong acids (not including nitrates) concentration is extremely high, making the water highly corrossive, especially for stainless steel. We need additionally p-alkalinity, m-alkalinity, Ca++, Mg++ and cooling liquid temperaure (what water is cooling). In which degrees you mention the temperature (80-100)? > Of course, citric acid will lower the m-alkalinity and pH, resulting in lower scaling, but you already have highly corrossive water and if you add more acid it will be even more corrossive. I suppose you have much corrosion under scale formations.

about alkalinity, there is alkalinity only in HERO Reject stream but the Softener reject has no Alkalinity so, not measured
pH mentioned in the attached analysis,
this streams will be heated through heat exchanger not cooled, temperature will be exchanged with distilled water.

About Corrosion, it will not affect our system more because we have duplex stainless steel,
