Development of a test method to assess the sludge reduction potential of aquatic organisms in activated sludge.

Abstract

This article shows the development of a quantitative sludge reduction test method, which uses the sludge consuming aquatic worm Lumbriculus variegatus (Oligochaeta, Lumbriculidae). Essential for the test are sufficient oxygen supply and the presence of a non-stirred layer of sludge for burrowing of the organisms. The test eliminates the unwanted effects of… (More)
