Tiivistelmä
This thesis is related to the Finnish government decree on treating domestic wastewater in areas outside sewer networks (542/2003). The aim of this thesis was to design a simple, cheap and effective domestic wastewater treatment system and build its model.
The thesis includes not only the theoretical explanations of methods for removing nitrogen, phosphorus and BOD7, engineering designed and building processes of model, but also the experimental processes of running the model and results of analyzed samples from the model. The analysis was done by the Maintpartner Laboratory.
The results prove the design is successful for treating domestic wastewater. However, the treatment methods still need to be adjusted if the design is going to be used in practice.
