INVESTIGATION OF FUNCTIONAL DIVERSITY AND ACTIVATED SLUDGE CONDITION USING BIOLOG® SYSTEM

microbial communities, collected from WWTP “Klimzowiec” in Chorzów with the excess sludge subjected to the purification process, and then long-term adaptation in laboratory conditions. Changes in the functional diversity of activated sludge during the adaptation in the lab-scale were verified. It was found that the acclimatization process plays a crucial role in sludge adaptation to the laboratory environment. In addition, it has been shown that subjecting the excess sludge to

CIRCULAR ECONOMY IN WASTEWATER TREATMENT PLANT

and sludge treatment processes, which change the overall objectives of the wastewater treatment plant operation. According to the current EU water policy [7], the primary duty of the sewage treatment plant was to protect the water environment. Nowadays, the plant must go beyond the traditional approach and focus not only on environmental, but also social and economic aspects (Fig. 1). Figure 1. Conventional wastewater treatment plant (WWTP) and N-E-W resource recovery facilities (after [6]) 3

ANALYSIS OF THE POSSIBLE APPLICATION OF DEAMMONIFICATION TECHNOLOGY IN THE MUNICIPAL WASTEWATER TREATMENT PLANT IN ZABRZE

deammonification (SD) application in reject water treatment is illustrated in Figure 2. Figure 2. Typical side stream deammonification (SD) application in a WWTP with activated sludge process [13]. SD: sidestream deammonification; RAS: return activated sludge; WAS: waste activated sludge Normally, reject water is led to the WWTP mainstream without separate treatment. Deammonification in sidestream can remove up to 90% of the internal nitrogen load in reject water. This way, nitrogen removal process in the
