Assessment of biodegradability of synthetic surfactants by tests simulating sewage treatment

The official German activated-sludge test for determining the biodegradability of synthetic surfactants is compared with a modified test in which the sludge is retained in a porous polythene vessel, and with a proposed standard filtration test. The advantages and disadvantages of the various tests a...
