  • Treatment of domestic wastewater using upflow anaerobic sludge blanket reactor

    This paper presents the findings of the study on treatment of domestic wastewater using a laboratory scale Hybrid Upflow Anaerobic Sludge Blanket (HUASB) reactor. The reactor with a working volume of 5.9 L and plastic cut rings as packing media was operated at varying Hydraulic Retention Time (HRT) for a period of 110 days. While the COD removal varied from 75-86%, the BOD removal was in the ...

  • Dairy shed wastewater treatment and modelling by anaerobic digestion technology

    There is a growing interest in the application of Anaerobic Digestion (AD) technology to Australian dairy farms not only for the reduction of environmental pollution caused by the effluents but also for recovering bioenergy. To be able to design and operate efficient AD systems, appropriate mathematical models need to be developed to observe and analyse the anaerobic process dynamics, such as the ...

  • Treatment of corn ethanol distillery wastewater using two-stage anaerobic digestion

    In this study the mesophilic two-stage anaerobic digestion (AD) of corn bioethanol distillery wastewater is investigated in laboratory-scale reactors. Two-stage AD technology separates the different sub-processes of the AD in two distinct reactors, enabling the use of optimal conditions for the different microbial consortia involved in the different process phases, and thus allowing for higher ...
