Abstract
To develop treatment technology information in support of the USEPA selenium drinking water regulation of 0.01 mg/L, the Drinking Water Research Division, USEPA, Cincinnati, OH, conducted laboratory jar tests and pilot plant tests for selenium IV and VI removal by conventional coagulation and lime-soda ash softening. This paper presents the results of these studies that showed removals to be dependent on the valence and concentration of selenium, type and dose of coagulant, and pH of the feed water. Selenium VI was poorly removed by both processes whereas selenium IV was moderately removed.
