The biodegradation of nitrilotriacetic acid (NTA, a detergent builder) in laboratory simulations of the activated sludge process was studied at 2 different concentrations of mixed liquor suspended solids. Responses to changes in the influent NTA concentration such as those which might be associated with a wash day were examined.
