The course gives the technological backgrounds of treatment processes applied for production of drinking water.
The treatment processes are demonstrated with laboratory experiments. Study goals: Knowledge of technological basics and design parameters of drinking water treatment processes
The course deals with the technological backgrounds of drinking water treatment processes:
1. Treatment scheme (ground water, surface water, infiltration water, bank filtration water);
2. Chemistry, microbiology;
3. Aeration and degasification (cascades, spray aeration, tower aeration);
4. Rapid filtration (filter materials, simple/dual media, up/down flow, pressure/gravitation, backwashing);
5. Activated carbon filtration (adsorption, pesticides);
6. Softening (carbonic-acid equilibrium, pellet reactor);
7. Micro and ultra filtration;
8. Nanofiltration and reverse osmosis;
9. Coagulation and flooculation;
Several unit operations used in drinking water purification – are simulated in pilot installations on laboratory scale. The unit operations are:
1. Activated carbon absorption;
2. Filtration of surface water;
3. Gas stripping;
4. Hydraulic aspects of filter materials;
5. Jar test;
8. Flocculent settling.
Different measuring techniques and chemical analyses are used to monitor the experiments. Where applicable, the experimental results are used to design a full scale treatment unit. Each experiment has to worked out in a report.
