Abstract
A new approach to the determination of biodegradable dissolved organic carbon (BDOC) is proposed, specially suited to water industry needs. It is a dynamic approach which uses circulating water continuously pumped over a biofilm attached to sand particles inside a glass column. The BDOC value corresponds to the DOC decrement when inlet and outlet water samples are compared. The time taken by BDOC analysis is less than two hours.
