Economical treatment methods are sought to remove the unregulated disinfection byproduct, N- nitrosodimethylamine (NDMA) from drinking water. This project tested photocatalytic oxidation using a UV-LED lamp and anatase phase titania (800 mg/L and 1200 mg/L). The first order rate of removal, best for the lower concentration, was compared to results for a mercury UV lamp. The comparison showed more efficient removal by the mercury lamp. As an addition to the project, the risk of NDMA in four major rivers was investigated.
