Tiivistelmä
Source separated human urine is an innovative approach to relieve the envi-ronmental stressors of wastewater treatment and fertilizer production since urine is a continuous source of wastewater and coincidentally accounts for the major nutrients essential for plant growth. This thesis tackles an ongoing chal-lenge in the treatment of source separated urine, where its aim is to investigate the use of advanced oxidation processes (AOP) for the removal of organic mat-ter and simultaneous determination of nitrogen availability from urine with vary-ing concentration factors.
The contents of this thesis will encompass optimal parameters for persulfate activation, COD removal, and nitrogen availability. The methods used to con-duct this thesis include literature reviews and laboratory work.
The obtained results indicate that persulfate AOP is an adequate treatment for nitrogen recovery where roughly 90% nitrogen availability was achieved for source separated urine with varying concentration factors. However, persulfate AOP indicates an inadequate treatment for the removal of organic matter. The presence of chloride ions in urine proves to be the leading cause for nitrogen losses and minimal organic matter removal.
