Anaerobic Reactors

Abstract

Preface ix Volume 1 (Wastewater characteristics, treatment and disposal) presents an integrated view of water quality and wastewater treatment, analysing wastewater characteristics (flow and major constituents), the impact of the discharge into receiving water bodies and a general overview of wastewater treatment and sludge treatment and disposal. Volume 1 is more introductory, and may be used as teaching material for undergraduate courses in Civil Engineering, Environmental Engineering, Environmental Sciences and related courses. Volume 2 (Basic principles of wastewater treatment) is also introductory, but at a higher level of detailing. The core of this book is the unit operations and processes associated with biological wastewater treatment. The major topics covered are: microbiology and ecology of wastewater treatment; reaction kinetics and reactor hydraulics; conversion of organic and inorganic matter; sedimentation; aeration. Volume 2 may be used as part of postgraduate courses in Civil Engineering, Environmental Engineering, Environmental Sciences and related courses, either as part of disciplines on wastewater treatment or unit operations and processes. Volumes 3 to 5 are the central part of the series, being structured according to the major wastewater treatment processes (waste stabilisation ponds, anaerobic reactors, activated sludge and aerobic biofilm reactors). In each volume, all major process technologies and variants are fully covered, including main concepts, working principles, expected removal efficiencies, design criteria, design examples, construction aspects and operational guidelines. Similarly to Volume 2, volumes 3 to 5 can be used in postgraduate courses in Civil Engineering, Environmental Engineering, Environmental Sciences and related courses. Volume 6 (Sludge treatment and disposal) covers in detail sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are fully described. Possible academic uses for this part are same as those from volumes 3 to 5. Besides being used as textbooks at academic institutions, it is believed that the series may be an important reference for practising professionals, such as engineers, biologists, chemists and environmental scientists, acting in consulting companies, water authorities and environmental agencies. The present series is based on a consolidated, integrated and updated version of a series of six books written by the authors in Brazil, covering the topics presented in the current book, with the same concern for didactic approach and balance between theory and practice. The large success of the Brazilian books, used at most graduate and postgraduate courses at Brazilian universities, besides consulting companies and water and environmental agencies, was the driving force for the preparation of this international version. In this version, the books aim...

The Effect of Anaerobic and Aerobic Fish Sludge Supernatant on Hydroponic Lettuce

“…However, most anaerobic effluents are characterized by high chemical oxygen demands (CODs), hydrogen sulfides (H 2 S) content, and low dissolved oxygen (DO) concentrations, and thus can be considered phytotoxic. In this case, a post-treatment (e.g., aerobic detoxification) for the anaerobic effluent is required before being directed to the plants [10][11][12].…”

Anaerobic treatment of rice winery wastewater in an upflow filter packed with steel slag under different hydraulic loading conditions

“…Although simple and easy to operate, a CSTR configuration has some limitations related to the slow growth of anaerobic microorganisms, particularly methanogens, such as low reaction rate and long hydraulic retention time (HRT). Extensive efforts have therefore been directed towards retaining a higher biomass density by decoupling the HRT and solids retention time (SRT), leading to the development of various high-rate anaerobic reactors, such as the upflow anaerobic sludge blanket (UASB), expanded granular sludge bed (EGSB), anaerobic filter, anaerobic baffled reactor, and membrane bioreactor (de Lemos Chernicharo, 2007). Such 'high-rate' anaerobic reactors are generally able to handle a higher organic loading rate (OLR), i.e., a shorter HRT, http://dx.doi.org/10.1016/j.biortech.2015.06.046 0960-8524/Ó 2015 Elsevier Ltd.
