Treatability assessments- batch versus continous culture tests

- By: ,

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. The real key to successful use of batch tests alone for conducting treatability assessment is an understanding of the conditions under which the test is run. Continuous 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 have the advantage of allowing sufficient time for culture acclimation and simulate full-scale operation more closely than batch tests.
