Aim: During the course the students learn how to do a draft design a water works for treatment of groundwater. In addition, the students do an experimental and theoretical analysis of the operation of a groundwater plant.
|
Contents: The course contains two major parts:
1. Design of a water works. First the treatment objectives are identified from the raw water analysis and current water quality standards, and the water demand and its variation is estimated. The design starts with an analysis of treatment alternatives, and after selection of treatment process, a draft design is carried out leading to drawings of the processes, a hydraulic profile, explanation of operation, and finally an estimate of capital and operating costs. This is explained in a short clients summary report for the city engineer, and in a more elaborate background report for the process engineers. The processes are aeration/stripping, adjustment of the carbonate buffer system by lime addition, etc., primary and secondary filtration, activated carbon treatment (solvents and a pesticide), UV-disinfection, and finally pumping of the water to consumers.
2. Analysis of water works operation. The operation of a near-by waterworks is analyzed based on the measurements of appr. 10 physical-chemical parameters. From this, the operation of the aeration/stripping, the filtration processes, and the state of the carbonate system is evaluated. Suggestions for improvements are made.
