Measuring Efficacy of Biological Cleaner Operations

This paper presents the results of investigations into the claims of biological cleaners. The primary advantage of biological cleaning would be that these systems digest oily soils removed from metal parts to carbon dioxide and water by way of a culture of suitable bacteria and other microbes. By directly measuring carbon dioxide evolved by representative biological cleaning systems with several soils, Henkel Technologies has quantified the amount of digestion to carbon dioxide and found it to be less than expected. We have modeled system dynamics and identified input and output balances within the system
