Tiivistelmä
With the attention paid to wastewater treatment, the process of wastewater treatment has been developing rapidly.
Activated sludge process has been widely used in wastewater treatment in recent years. The purpose of this study is
to research how to start, run and optimize the pilot sewage treatment plant built for educational and research
purposes in Savonia UAS. The wastewater and sludge used in the study come from local wastewater treatment
plant situated in Lehtoniemi (Kuopion Vesi) in Kuopio, Finland.
The object of this study is the gain the knowledge needed for operating the pilot wastewater treatment plant.
Through studying and researching the pilot, we can have a certain understanding of the treatment of wastewater by
activated sludge process and at the same time we are getting familiar with the equipment, automation system and
basic principles and the connections of the unit operations taking place in the pilot process.
The most important thing of activated sludge process is the activity of sludge, and the activity of sludge is related to
the number of micro-organisms and the living environment of micro-organisms. In order to keeep the activity of
activated sludge at a high level, it is necessary to keep the amount of activated sludge in the process in a certain
range and at the same time control pH, temperature, oxygen and other conditions under the requirements of
microbial survival. Optimal conditions for each activated treatment plant are unique, so testing and optimizing of the
process is needed in all activated sludge wastewater treatment plants.
