Abstract

Application of moving bed in wastewater treatment plants allows achieving multiple technological benefits, but requires implementation of a complicated acclimation period. Immobilization of the biomass in the form of biofilm on the carrier makes this technology resemble activated sludge technology. That provides additional profits, i.e. no necessity for sludge recirculation, what lowers operating costs, and elimination of the unfavorable sludge bulking. It also guarantees the independence of biomass retention time from wastewater hydraulic retention time, favoring the development of nitrifiers. Furthermore, biomass suspension in the whole capacity of the reactor ensures high effectiveness of wastewater treatment (McQuarrie & Boltz, 2011). Development of a biofilm of appropriate thickness and containing necessary microorganism groups is a difficult and a very time-consuming task. The factors, which decisively influence the biofilm immobilization are: characteristics of the influent, concentration of oxygen in the aerobic phases and the mixing strategy. The aim of this research was successional development of biofilm on the EvU carrier elements in a laboratory scale SBR (rich in appropriate groups of microorganisms for nutrient removal).
