520	3 |a"Biodegradability testing of nonionic surfactants was performed by the 0.E.C.D. dynamic simulation (confirmatory) test. A bench-scale activated sludge plant was used with a continuous flow of synthetic sewage containing the surfactants to be tested. Details of operation and modifications to prevent excessive foaming are described. These techniques can be modified for testing the biodegradability and intermediate products of other classes ofcompounds. Results showed the extent of primary biodegradation of the three nonionic surfactants tested followed the order: linear primary alcohol ethoxylate >> nonylphenol ethoxylate > branched alkylphenol ethoxylate"--Abstract, page 1.
