| Summary: | In this dissertation, conventional processes for oily wastewater treatment were discussed and
dissolved air flotation (DAF) coupled with flocculation pretreatment was proposed as the
most effective process to remove emulsified oil from wastewater mainly due to the reasons
that microbubble, longer residence time and quiescent hydrodynamic conditions provided by
DAF process are essential to effectively separate emulsified oil from wastewater.
Subsequent studies mainly focused on the factors affecting the flocculation and dissolved air
flotation process, surface science of air flotation, and optimization of operating parameters
which are essential to achieve optimal removal efficiency. |
