Selected Computations in Water Treatment Technology

FCH-MCO_VVTAcad. year: 2011/2012

In framework of course are explained selected processes and computations from water technology, which are oriented on general and typical problems of field of water technology (drinking and waste water treatment). Subject matter is replenish by fundamental questions associated with processes of selfpurification in surface water and by probabilistic assessment of water quality.
