Description:
A distilled water shake test, the elutriate test, was developed and tested to provide a fast, simple, procedure for predicting the escape of pollutants from treated and untreated sludges. The preliminary test consisted of subjecting various treated and untreated flue gas desulfurization (FGD) and industrial waste sludges to the elutriate test procedure and measuring the levels of a wide variety of constituents in the elutriate and comparing these with analyses of digested sludges. The resulting data are presented as percent attenuation and a comparison is made between treated and untreated wastes. The shortterm elutriate test results were compared to results of a longterm leaching test using the same treated and untreated sludges. The results suggest that the elutriate test may be useful in predicting the pollutant potential of various treated or untreated wastes. Further research and modifications are suggested to improve the predictive value of the test.
