A MULTIPARAMETER ANALYSIS OF VOLATILE ORGANIC-COMPOUND EMISSIONS FROMSEWERS

A wide range of parameters affect the extent of volatile organic compo und (VOC) stripping from municipal and industrial sewers. These parame ters can generally be classified as VOC physicochemical properties, wa stewater fluid properties, wastewater flow conditions, and sewer gas n ow conditions. However, because of the continuous spectrum of possible parameter combinations, previous studies related to VOC emissions fro m sewers have been based on highly simplifying assumptions that repres ent only a small subset of parameter values. A computational model was used to simulate greater than 2.5 million parameter combinations. A f requency array approach was used to facilitate a semiquantitative asse ssment of parameter combinations that lead to high VOC stripping effic iencies. Results were interpreted in terms of their practical signific ance with respect to industrial discharge control and VOC emissions re duction.
