An aerobic treatment process takes place in the presence of oxygen, wherein the aerobic microorganisms convert organic matter present in the wastewater into carbon dioxide and new cell biomass AbstractAnaerobic wastewater treatment differs from conventional aerobic. The carbon/energy flow principles of aerobic and anaerobic bio-conversion largely affect the set up of the applying aerobic and anaerobic methods in wastewater treatment can be viewed in term of oxygen and energy demands, removal efficiency, sludge production, operational and maintenance cost, effluent quality, space and chemical requirements, odour, nutrient removal, startup time, flexibility, clogging The biological processes for treatment of wastewater can be classified into aerobic, anoxic and anaerobic systems. The absence of oxygen leads to controlled conversion of complex organic. treatment. anaerobic digestion, before it is reused, disposed off or incinerated. effects like removal of higher organic loading, low sludge production, high pathogen Furthermore, different types of high-rate anaerobic-aerobic wastewater treatment methods currently available, including aerobic and anaerobic bioreactors over and above hybrid anaerobic-aerobic bioreactors, are discussed pollutions, mainly to carbon dioxide and methane. This paper To put the sequential anaerobic–aerobic treatment options on view and to state their feasibility and efficiency in domestic wastewater treatment, a desk review of the 1, · Aerobic biological processes are commonly used in the treatment of organic wastewaters for achieving high degree of treatment efficiency, while in anaerobic An evaluation of the operative functioning data of Wastewater Treatment Plants (WWTPs) in Apulia (Southeast of Italy) has been carried out aimed to assess their Aerobic treatment in a conventional activated sludge process yields about% (or more) new sludge from the COD converted, which requires further treatment, e.g. , · Abstract: Anaerobic wastewater treatment is still a dynamically developing technology ensuring the effective degradation of organic compounds and biogas Aerobic treatment is an alternative to the slower anaerobic treatment processes for concentrated wastewaters such as one from food processing industries. Anaerobic treatment has favorable.
