ABSTRACT

This chapter discusses two Advanced Wastewater Treatment (AWT) Facilities which serve approximately 700,000 people in two counties. Both AWT's include the processes of nitrification and ozone disinfection following conventional primary sedimentation and bioroughing trickling filter processes. With the implementation of an Industrial Pretreatment Program, it became necessary for the City to address the potential problems associated with the disposal of septage at the AWT. The primary area of investigation of the study involved the generation of a data base which could be used to evaluate the impact of septage on the treatment processes and to determine and assess the extent of any existing regulatory problems. The Industrial waste Section increased surveillance activities on several haulers. The system of tracking and billing the haulers was also evaluated. During the phase of the study it was discovered that there were several haulers who had substantial unpaid balances for septage dump fees.
