1.4 AimThe aim of this thesis work is to try to identify all the methods that have evolved over the years at treating reject water from dewatering sludge. From the introductory part of this thesis based on referenced literature, studies on sludge liquor treatment have been done independent of the wastewater treatment plant as a whole. It has specifically looked at nitrogen or phosphorus removal based on particular systems depending on the type of study, without looking at its’ effect on a year round operation of the plant. Such as treatment by biological, physical, chemical methods and the type of reactor configuration that achieves nutrient removal. This thesis attempts to bring all the treatment methods in a single source and with a descriptive list of the treatment processes provide easy reference for adaptation of the technology.More so, find what factors have stimulated the continued interest at improving the technology of reject water treatment. Trace how the discoveries of new processes in the biological cycle from different parts of Europe; deammonification in Switzerland, Holland, Germany and Sweden, oxygen-limited autotrophic nitrification-denitrification (OLAND) in Belgium and complete autotrophic nitrogen removal over nitrite (CANON) process in Holland are shaping8Francis Narteh Ocansey, Master Thesis-WaterLu, 2005advanced research in sludge liquor treatment and management. Lastly evaluate the applicability of these processes at treating sludge liquor from 2 WWTPs in Sweden.
