This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.
In civil engineering, quicksand is more than just a puddle of mud! The "quick condition" occurs when seepage reduces the effective stress of a soil. This can lead to some dangerous conditions, especially if the seepage causes piping erosion to occur at a dam.
