Aim: During the course the students learn how to do a draft design of a wastewater treatment plant based on prior analysis of treatment alternatives. At the same time the students obtain a practical oriented insight in the treatment processes which enhances the theoretical understanding. The aim is also to learn to present a project appropriately.
|
Contents: Based on the effluent quality requirements and the composition of the raw sewage, treatment alternatives are outlined and discussed. After selection of process alternative, the draft design is based on both relatively simple hand-calculations and on computer simulation of the biological processes. The computer simulations are also used to analyse the dynamic behaviour of the treatment process, for example during a snow melt event. The design leads to drawings of the processes, explanation of operation, including treatment stability, and finally an estimate of capital and operation costs. This is explained in a short client's summary report for the city engineer, and in a more elaborate background report for the process engineers. The processes involved are activated sludge plants for organic matter removal, nitrification and denitrification, phosphorus removal by chemical and biological processes, sand filtration and aeration, and finally sludge stabilization and sludge dewatering.
