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.
"," as the word suggests, is the addition of limestone (calcite), primarily calcium carbonate (CaCO3), to neutralize acid waters and soils and buffer them from rapid fluctuations in pH. Limestone typically is applied to lawns, gardens, pastures, and croplands to supply calcium, an essential plant nutrient, and to decrease soil acidity.
