ABSTRACT
This chapter presents a case study in the application of the batch activated sludge process. This particular application of this technology is somewhat unique in that it was instituted in place of a completely new physical/chemical treatment facility which was found to be incapable of meeting the permit requirements. Given the limited amount of time allowed for treatability, development of design criteria, and installation of the equipment, the application has proven to be quite successful. The general scope of the project was to perform wastewater treatability evaluations for development of an upgrade alternative for their existing wastewater treatment system. Evaluation of the treatability data collected over four weeks of continuous operation indicated the process to be viable and capable of achieving the desired level of treatment. The process requirements included nutrient additions, alkalinity addition, and antifoam addition. The estimated dosages for these chemicals were deferred for definition during full-scale operation.
