Neke mogućnosti unapređenja energetske i ekološke efikasnosti centralnog postrojenja za prečišćavanje otpadnih voda u Kragujevcu

Abstract

The process of co-digestion or co-fermentation is a digestion process that involves a homogenous mixture of two or more substrata. One of the reasons for usage of co-digestion is the magnitude of digesters in the wastewater treatment plants, and there is also a possibility to add a co-substrate, which increases production of biogas. This paper gives the estimate of possible usages of organic waste made in slaughter houses as well as the estimate of possible usages of food residues in the restaurants located in the nearby of the central wastewater treatment plant for the city of Kragujevac. The possibility to use wastewater from the galvanization plant for purification of biogas produced in the wastewater treatment plant is also studied.
