The main aim of this Master’s thesis project is to investigate how type 0041 is affected by different ozone dosages and reaction times, and thereafter propose new ozonation strategies at Klagshamn WWTP.
A literature survey should be performed to increase the knowledge about filamentous bacteria type 0041 and possibly other filamentous microorganisms that is favored by the absence of M. parvicella. Also people at other WWTPs that have used ozonation to prevent bulking sludge should be contacted and interviewed about their experiences. Full-scale tests at Klagshamn of different ozone dosages and reaction times should be evaluated by activity tests and microscopic characterisation of the ozonated sludge.
