ABSTRACT

As discussed in Chapter 2, air quality regulations will, in some instances, require that emissions from wastewater treatment plants be controlled. In addition, the regulations often will, at a minimum, require control technologies to be evaluated to determine their technical feasibility and cost effectiveness. This chapter summarizes the technologies available to control emissions from POTWs. It includes an overview of control technologies, criteria for evaluation and rating and summaries of performance of each major technology category. This information can be used as part of a cost effectiveness evaluation required when a control technology standard such as best available control technology (BACT) must be applied. This evaluation process is described in Chapter 16. Control technologies can also be used to reduce emissions to avoid certain regulatory and permitting requirements.
