Background: Moving bed biofilm reactor (MBBR) is one of the new hybrids biological systems that are used in treatment of wastewater contaminated by organic and nitrogen pollutant. In this study, the continuously operated laboratory scale Kaldnes(k1) moving bed biofilm reactors (MBBRs) was investigated. Methods: In this system, two series as Anoxic reactor (R1) and aerobic (R2) have a size 3...

VOCs comprise both methane (CH 4) and non-methane volatile organic compounds (NMVOCs). NMVOCs are defined as " all those artificial organic compounds different from methane which can produce photochemical oxidants by reaction with nitrogen oxides in the presence of sunlight " .
Nitrogen is one of the most important ecosystem nutrients and often its availability limits net primary production as well as stabilization of soil organic matter. The long-term storage of nitrogen-containing organic matter in soils was classically attributed to chemical complexity of plant and microbial residues that retarded microbial degradation. Recent advances have revised this framework, ...
