Abstract
U ovom je radu prikazana teorija taloženja koja se primijenjuje u procesu obrade otpadnih voda. Otpadne su vode različitog porijekla i sastava, obzirom na podrijetlo, pa u skladu s time prolaze četiri stupnja pročišćavanja vode – primarni, sekundarni, tercijarni i napredni. Taloženje otpadnih voda dio je prvoga stupnja obrade vode te se njime uklanjaju krute čestice. Općenito govoreći, taloženje je proces u kojem čestice suspenzije padaju na dno uslijed sile gravitacije ili centrifugalne sile. Spremnik u kojem se odvija taloženje djelovanjem sile gravitacije naziva se taložnik. Ispravno dimenzioniranje taložnika preduvjet je za djelotvorno odvajanje. Najvažniji korak dimenzioniranja je utvrđivanje površine taložnika. Razvijene su različite metode obrade eksperimentalnih podataka, poput Coe-Clevengerove, Kynchove i Talmage-Fitchove, koje se mogu primijeniti za dimenzioniranje taložnika. Eksperimentalno je proveden šaržni test taloženja, a potom je Talmage-Fitchovom metodom proveden postupak proračuna potrebne površine taložnika.
Abstract (english)
In this paper, the theory of sedimentation is applied to the process of wastewater treatment. The composition of wastewater varies depending on its origin and undergoes four stages of water purification accordingly – primary, secondary, tertiary and advanced stage. Wastewater sedimentation is a part of primary water treatment and it removes sedimentary solid particles. Generally speaking, precipitation is a process in which suspension particles recede to the bottom due to the force of gravity or centrifugal force. The tank in which precipitation takes place is called a precipitator. In order to have an effective separation, proper sizing of the precipitator is required. The most important dimensioning step is to determine the surface of the precipitator Various experimental data processing methods have been developed, such as Coe-Clevenger, Kynch, and Talmage-Fitch, which can be applied to precipitator sizing. A batch settling test was experimentally conducted, and then the required precipitator area was calculated using the Talmage-Fitch method.
