Description:

Druhy a chemické složení vod. Hlavní zdroje znečitování vod. Zdroje pitné a užitkové vody. Infiltrace, jímání podzemních a povrchových vod. Zásobování vodou. Požadavky na jakost pitné, užitkové a provozní vody. Úprava podzemních vod (odkyselování, odželezňování a odmanganování). Úprava povrchových vod (mechanické předčištění, usazování, zahušťování, flotace, filtrace, čiření, adsorbce a hygienické zabezpečení vody). Speciální technologie úpravy vody (iontoměniče, destilace, ultrafiltrace, reverzní osmóza, elektrodialýza, odsolování mořské vody, denitrifikace a příprava ultračisté vody). Úprava užitkové a provozní vody (zemědělství, stavebnictví, energetika a vybraná průmyslová odvětví). Základní procesy čištění komunálních a průmyslových odpadních vod (aktivace, biofiltry, anaerobní stabilizace, srážení).
