UASB (upflow anaerobic sludge blanket) reactors have been recognized as a viable option for sewage treatment. However, in order to improve the effluent quality, some type of post-treatment must be implemented. The aims this study were (i) establish start-up methodology full-scale anaerobic–aerobic system treating sewage, (ii) evaluate concentrations different constituents influent and aerobic w...

A two stage sequential Fenton's oxidation followed by aerobic biological treatment train was used to achieve decolorization and to enhance mineralization of azo dyes, viz. Reactive Black 5 (RB5), Reactive Blue 13 (RB13), and Acid Orange 7 (AO7). In the first stage, Fenton's oxidation process was used while in the second stage aerobic sequential batch reactors (SBRs) were used as biological proc...

The biological stabilisation of the organic fraction of municipal solid waste (OFMSW) into a form stable enough for land application can be achieved via aerobic or anaerobic treatments. To investigate the rates of degradation (e.g. via electron equivalents removed, or via carbon emitted) of aerobic and anaerobic treatment, OFMSW samples were exposed to computer controlled laboratory-scale aerob...

Aerobic granular sludge (AGS) is a recent innovative technology and considered forthcoming biological process for sustainable wastewater treatment. AGS composed of the dense microbial consortium aerobic, anaerobic, facultative types bacteria. The mechanism formation its stability long-term operation still subject current research. On other hand, makes treatment in cost-effective way. However, o...

IntroductionMigraine is a complex headache to treat, often with an unsatisfactory clinical response. Aerobic exercise, such as running, can be non-pharmacological treatment reduce migraine attacks.ObjectiveThis systematic review meta-analysis investigated the effects of running on frequency and intensity pain in subjects compared other or no aerobic exercise.MethodsRandomized quasi-randomized t...

BACKGROUND Patients with stress-related exhaustion suffer from cognitive impairments, which often remain after psychological treatment or work place interventions. It is important to find effective treatments that can address this problem. Therefore, the aim of this study was to investigate the effects on cognitive performance and psychological variables of a 12-week aerobic training program pe...

anaerobic bacteria are well known causes of sepsis in adults but there are few studies regarding their role in neonatal sepsis. in an attempt to define the incidence of neonatal anaerobic infections a prospective study was performed during one year period. a total number of 400 neonates under sepsis study were entered this investigation. anaerobic as well as aerobic cultures were sent. the pati...
