Abstract
The effectiveness of conventional drinking water treatment and lime softening was evaluated for beryllium removal from two drinking water sources. Jar test studies were conducted to determine how common coagulants (aluminum sulfate and ferric chloride) and lime softening performed in removing beryllium from spiked waters. Centrifugation was used to simulate filtration. The two source waters used were raw Ohio River water and groundwater from the Great Miami Aquifer. The impact of initial beryllium concentration, coagulant dose, turbidity and pH on beryllium removal was examined and optimum treatment conditions were determined. Jar tests using alum and ferric chloride coagulants were able to achieve 95% and 85% removal of beryllium respectively from surface water. Removal efficiency increased as the pH was increased. Based on the data collected in the study, coprecipitation and precipitation are the two likely mechanisms responsible for beryllium removal.
