  • Alternatives for energy production in aerobic wastewater treatment facilities

    Using technologies such as anaerobic digestion for energy generation from wastewater demands a change in infrastructure that several treatment works are not prepared to immediately implement. This works explores the use of energy production technologies to increase the sustainability of conventional aerobic wastewater treatment plants. The first option considered sludge (a by-product from ...

  • Factors affecting the performance and risks to human health of on-site wastewater treatment systems

    Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...

  • Sludge-bed anaerobic membrane bioreactor treating prehydrolysis liquor (PHL): correlation of cATP™ with performance parameters

    Cellular adenosine triphosphate (cATP™) may be used to characterize the biological degradation activity within the anaerobic and aerobic wastewater treatment systems. The feasibility of using cATP™ as a process monitoring parameter for an anaerobic membrane bioreactor was evaluated. Results obtained from batch respirometric anaerobic treatability studies and a continuous sludge-bed ...

  • Future Perspectives in Bioreactor Development

    The paper discusses conversion capacities of both anaerobic and aerobic wastewater treatment systems in relation to growth kinetics, hydrodynamics and biomass concentration. In the current modern anaerobic high-rate reactors the conversion potentials are optimally exploited. This is not yet true for aerobic systems since operation of aerobic systems under conditions of low biomass growth reduces ...

  • Performance of a fixed-bed biofilm reactor with microbubble aeration in aerobic wastewater treatment

    Microbubble aeration is supposed to be highly efficient for oxygen supply in aerobic wastewater treatment. In the present study, the performance of a fixed-bed biofilm reactor microbubble-aerated using a Shirasu porous glass (SPG) membrane system was investigated when treating synthetic municipal wastewater. The biofilm formation on the carriers was enhanced with microbubble aeration due to ...

  • The effects of different aeration patterns on aerobic granulation

    In this study, the effects of aeration patterns in terms of intra- (S1) and extra- (S2) aeration on aerobic granulation were investigated. Granules developed in S1 were retarded due to the high shear force of highly mixed air bubbles, and they were more solid while the S2 granules were porous with many distinct pores and channels. Mature granules in two series had comparable specific oxygen ...

  • The effect of mixing conditions on anaerobic digester performance

    The basic principle of aerobic wastewater treatment is the conversion of some parts of organic matters to biomass and this causes production of excessive sludge in aerobic processes. This excessive sludge is withdrawn from time to time to prevent accumulation of biomass in aeration basin. In most cases, this sludge requires the stabilization before the dewatering and disposal. Different processes ...

  • Porous structure and spatial characteristics of aerobic granules

    Cryosectioned granules were observed in microstructure, Extracellur Polymeric Substances (EPS) and metal distribution. Aerobic granules composed of pores and channels that were not plugged by EPS, with rather open structure. Microorganisms proliferated mainly on the surface of granule and on the wall of channels, carbohydrate EPS mainly distributed on the surface of granules, and protein EPS ...

  • Towards advanced aeration modelling: from blower to bubbles to bulk

    Abstract: Aeration is an essential component of aerobic biological wastewater treatment and is the largest energy consumer at most water resource recovery facilities. Most modelling studies neglect the inherent complexity of the aeration systems used. Typically, the blowers, air piping, and diffusers are not modelled in detail, completely mixed reactors in a series are used to represent plug-flow ...
