  • Limestone for pH Adjustment in Industrial Wastewater

    Limestone pH Adjustment Systems The use of limestone for pH adjustment was once widespread. However its use today as a treatment step must be considered carefully.. In a typical limestone treatment system influent flows enter the bottom of a limestone retention tank. Flow percolates up through the limestone bed and out the top of the tank.
