ABSTRACT
ABSTRACT: The paper presents studies on wastewater treatment in a sequencing batch reactor using keramsite grains as the moving bed biofilm PCMBSBBR (Porous Carrier in Moving Bed Sequencing Batch Biofilm Reactor). With municipal wastewater and PCMBSBBR technology, the study demonstrated high average removal efficiencies – of 96.5; 85.2; and 91.3% respectively for COD, TN and TP. Analyzed technology has examined the effects of wastewater treatment systems with respect to MBSBBR with conventional plastic carriers. Unfortunately, this type of keramsite grains that was used in the study proved to be unsuitable in moving bed biofilm technology.Analyzed keramsite had relatively low mechanical strength, which appears during the study. Fur-ther studies using keramsite grains are required. It is necessary to use of keramsite with better mechanical properties than ever before to grain and clashed not crumble. Key conclusions of this studies have identified a new line of research into the use of powdered form of keramsite in activated sludge technology in sequencing batch reactor.
