ABSTRACT:
The present invention involves a system and method of making ferric chloride with reduced amounts of hydrochloric acid for water treatment. The method comprises preparing a reactant batch comprising ferric oxide and hydrochloric acid at a predetermined molar ratio. The method further includes mixing the reactant batch with an impeller rotating between about 60 and 150 revolutions per minute. The method further includes maintaining the reactant batch at a temperature between about 70° Fahrenheit and 180° Fahrenheit. The method forms a reaction product including ferric chloride and a reduced amount of hydrochloric acid.
