Treatability Assessments: From Bench to Field-Scale Testing

Abstract

Batch and continuous culture reactors are used widely for conducting treatability assessments of industrial wastewaters. Batch tests have the advantage of producing results on a rather rapid basis – typically hours or a few days. The major disadvantage of batch tests is that they represent a short-term response of a seed culture to the test wastewater and can be affected by toxicity, lack of acclimation, or initial dilution effects. Continuous laboratory-scale reactor tests provide more realistic measures of treatability but require operation for sufficient lengths of time to allow steady-state conditions to be approached. Continuously operated reactors simulate fullscale operation more closely than batch tests. Laboratory-scale pilot tests provide a realistic simulation of anticipated full-scale operating conditions and provide a reliable alternative to costly field-scale pilot tests. The objective of this paper is to show how laboratory-scale pilot tests can be used to avoid costly field-scale pilot testing.

Treatability assessments using batch-fed reactors have the advantage of producing results on a rather rapid basis – typically hours or a few days but the results can be affected by toxicity, lack of acclimation, or initial dilution effects. Continuous laboratory-scale reactor tests provide more realistic measures of treatability and have the advantage of allowing sufficient time for culture acclimation but require operation for sufficient lengths of time to allow steady-state conditions to be approached. Laboratory-scale pilot tests provide a realistic simulation of anticipated full-scale operating conditions and thereby provide a reliable alternative to costly field-scale pilot tests.
