ABSTRACT

In order to assess sewage treatment technology necessary to achieve water quality criteria in the watershed and to ensure best treatment technology is applied in building and expanding PSTWs when establishing the Watershed Sewer System Maintenance Plan, it is necessary to develop assessment guidelines to determinate the best treatment technologies applicable to the public sewage treatment works(PSTWs). Sewage treatment technologies such as anaerobic-anoxic-aerobic treatment process are employed at PSTWs, and treatment efficiency varies due to many factors such as how the PSTWs are operated. Therefore, analyzing assessment guideline of best available technology(BAT) using currently in USA and EU, this study presents assessment parameters for the assessment guidelines to be used in determining the best treatment technologies applicable to PSTWs. We have a plan to implement pilot assessment in preparation for the final assessment guidelines based on the results of professionals survey and to determine weighted factors and assessment parameters using analytic hierarchy process (AHP).
