Elucidating the mechanism and parameters influence of the gas phase (air bubbles) in the separation of oil from a complex oil-in-water emulsion

The destabilization of a hexadecane, water, and baker’s yeast (O/W/Y mixture) emulsion by aeration and formation of a clear oil layer was investigated. The role of the air bubbles to destabilize the emulsion and form a clear oil layer was observed on previous research, but not investigated further until the current research. Initial hypotheses...

Biological drinking water treatment of anaerobic groundwater in trickling filters

Drinking water production from anaerobic groundwater is usually achieved by so called conventional techniques such as aeration and sand filtration. The notion conventional implies a long history and general acceptation of the application, but doesn’t necessarily mean a thorough understanding of the processes involved. This is certainly the case...

Air bubbles for water quality improvement

Thermal stratification in water supply reservoirs can result in a serious degradation in water quality. The techniques of artificial mixing and aeration, using air bubbles, have been applied in a number of impoundments to prevent the formation of the anaerobic conditions that lead to poor water quality. The first part of this report describes...
