Landfill leachate treatment by advanced
oxidation process (AOP)
Background:

More stringent regulations in Norway for landfill leachate discharge to a water
body requires an advanced effluent treatment

AOP proved as a viable element concerning the characteristics of landfill
leachate and the given Nordic environmental conditions:

(AOP definition: generation of hydroxyl radicals for organic compound
degradation)
Tasks:

Comparison of electrolysis and ozonation (two different AOPs) with regard to
their performance on organic pollutant degradation

Degradation kinetics and pathways will be studied under cold climate conditions,
in dependence on different treatment conditions

Monitoring of hydroxyl- and other possibly formed radicals during the oxidation
process
Tools:

Electrolytical cell & ozonoation reactor

Advanced analytical methods

Enhanced Biological Phosphorous Removal (EBPR)
in flow through Moving Bed Biofilm Reactor (MBBR)
Projects: RECOVER
The enhanced biological phosphorus removal (EBPR) process is
increasingly popular as a sustainable method for removal and
subsequently recovery of phosphorus (P) from wastewater. The
overall aim of this project is to carry out the EBPR in a flow through
biofilm process utilizing a pilot-scale Moving Bed Biofilm Reactor
(MBBR).
Task:
 Investigating the effect of
wastewater quality and
operational parameters on the process performance

Treatment of produced water
Chemical cleaning protocols for ceramic membranes used in
produced water treatment. As we all know, irreversible fouling is the
major obstacle in the widespread application of membrane
technology.
For the project, the student could write a literature review about
chemical cleaning of membranes in the filtration of oily wastewater.
For the later master thesis, he/she could carry out experiments of
different chemical cleaning protocols (based on the literature
review) on three types of ceramic membranes of different materials,
i.e., alumina, titania and zirconia. The optimum protocols will be
selected based on the membrane permeability recovery,
permeability decline trend and possible damage caused by
cleaning.
