Abstract

Investigation of flow structures and mixing processes in separation tank models A.J. Kuck, E. Freistiihler, G. Rouve fn^We /or gi/drWic Engweermg Ma^ageme^ Aachen [/mverg^y o/ Aachen, Germany ABSTRACT The basic processes of multi-phase interaction and tank hydraulics in light liquid separators are worked out thus defining the requirements for set-up and operation of physical model studies. Appropriate in-field and laboratory measurement techniques are presented which allow a detailed study of the internal flow structures of the tanks. INTRODUCTION A major source of environmental contamination are hazardous light liquids which are dispersed in water and which discharge to natural water bodies. Especially industrial plants which handle large quantities of these substances have to be supplied with technically reliable separation facilities. Widely propagated measures for this purpose are hydraulic separation tanks which depend on the gravity effect, i.e. on the buoyancy
