This study investigated the occurrence and removal of 12 antibiotics (ciprofloxacin, enrofloxacin, levofloxacin, norfloxacin, nalidixic acid, azithromycin, clarithromycin, roxithromycin, lincomycin, novobiocin, sulfamethoxazole, trimethoprim) at four sewage treatment plants (STPs): two STPs in Kyoto, Japan and two STPs in Beijing, China. The STPs differed in design and operation conditions, uti...

in this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. for nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...

Although biological treatment of sewage by activated sludge or trickling filters is widely practiced, these processes still give rise to difficulties. The difficulties may be due to sludge bulking during the activated sludge process or to clogging during the operation of trickling filters. In his studies of biofilters and standard filters, H. Heukelekian (Sewage Works J. 17:23, 516, and 743, 19...
