Voda je višenamjenski resurs nužan za život svih živih bića. Voda koja se koristi za ljudsku potrošnju mora biti zdravstveno ispravna, odnosno ne smije sadržavati patogene mikroorganizme, toksine ili štetne tvari. Često voda ima različit mikrobiološki i kemijski sastav koji uvjetuje okolina iz koje se voda zahvaća. U cilju isporuke zdravstveno-ispravne vode za ljudsku potrošnju, nužno je osigurati kvalitetu vode propisanu zakonskom regulativom primjenom pojedinih metoda prerade. Pri tome se najčešće primjenjuje filtracija, taloženje, koagulacija i flokulacija, dezinfekcija i mekšanje vode. U ovom radu prikazani su procesi prerade vode za ljudsku potrošnju grada Slavonskog Broda. Proces započinje crpljenjem podzemne vode na vodocrpilištu Jelas a zatim prerađuje u pogonu. Voda se crpi iz pet bunara, od kojih svaki ima kapacitet 50 l/s. Sirovu podzemnu vodu vodocrpilišta Jelas karakteriziraju povišene koncentracije amonijaka, mangana, sumporovodika i željeza te je vodu prije isporuke potrošačima nužno preraditi. U tu svrhu podzemna sirova voda vodocrpilišta Jelas prolazi sustav tehnološke prerade koji se sastoji od DUAL – MEDIA filtracije, filtracije filtrima s aktivnim ugljenom te ozonizacije vode. Water is a multipurpose resource, which is necessary for the life of all living beings. Water used for human consumption must be wholesome and clean, respectively it must not contain microorganisms, toxins, or harmful substances. Water often has various microbiological and chemical compositions because it contains substances that get into it from the soil or atmosphere. In order to provide people with wholesome and clean water, we implement numerous purification methods. The most common water treatment methods are filtration, sedimentation, coagulation and filtration, disinfection, and water softening. This paper presents the processes of drinking water treatment in the city of Slavonski Brod. Jelas water pumping station draws and processes groundwater for human consumption. As a source, it uses five wells, each of which has a capacity of 50 l/s. Raw water from the Jelas pumping station has increased concentrations of ammonia, manganese, hydrogen sulfide, and iron. For this reason, certain parameters are monitored daily after certain stages of water treatment. Processing underground raw water from the Jelas pumping station is carried out by DUAL – MEDIA filtration, filtration with activated carbon filters, and previous ozonation of water. |
