Book Synopsis Change in Sludge Settling and Filtration Properties and Membrane Fouling Trends in MBR Activated Sludge Systems Operated at Different Solids and Hydraulic Retention Times by : Minghao Sun
Download or read book Change in Sludge Settling and Filtration Properties and Membrane Fouling Trends in MBR Activated Sludge Systems Operated at Different Solids and Hydraulic Retention Times written by Minghao Sun and published by . This book was released on 2014 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane bioreactor (MBR) activated sludge process is increasingly used in wastewater treatment due to its excellence in solid-liquid separation and superior effluent quality, smaller bioreactor volume and foot print. However, operational issues such as membrane fouling and sludge bulking affect its broad applications. As solids retention time (SRT) and hydraulic retention time (HRT) are the most important operating parameters in activated sludge systems, this research determined the effect of different SRTs (180 d, 90 d and 45 d) and HRTs (24 h, 12 h, and 6 h) on the change in sludge settling and filtration properties and membrane fouling trends while keeping the SRT/HRT ratio constant throughout the study period. The biomass concentrations increased from about 8,000 to 10,000 mg COD/L as SRT and HRT decreased proportionally. As SRT decreased to 45 d and HTR decreased to 6 h, significant sludge bulking and poor filtration with high Time to Filter (TTF) values were observed, largely due to the operation at low DO concentrations under high organic loading conditions. However, the system recovered in about 50 d after correction of low DO concentrations in the MBR.

This book was released on 2017-06-15 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.

Book Synopsis Post Treatments of Anaerobically Treated Effluents by : Vinay Kumar Tyagi
Download or read book Post Treatments of Anaerobically Treated Effluents written by Vinay Kumar Tyagi and published by IWA Publishing. This book was released on 2019-06-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anaerobic process is considered to be a sustainable technology for organic waste treatment mainly due to its lower energy consumption and production of residual solids coupled with the prospect of energy recovery from the biogas generated. However, the anaerobic process cannot be seen as providing the ‘complete’ solution as its treated effluents would typically not meet the desired discharge limits in terms of residual carbon, nutrients and pathogens. This has given impetus to subsequent post treatment in order to meet the environmental legislations and protect the receiving water bodies and environment. This book discusses anaerobic treatment from the perspective of organic wastes and wastewaters (municipal and industrial) followed by various post-treatment options for anaerobic effluent polishing and resource recovery. Coverage will also be from the perspective of future trends and thoughts on anaerobic technologies being able to support meeting the increasingly stringent disposal standards. The resource recovery angle is particularly interesting as this can arguably help achieve the circular economy. It is intended the information can be used to identify appropriate solutions for anaerobic effluent treatment and possible alternative approaches to the commonly applied post-treatment techniques. The succeeding discussion is intended to lead on to identification of opportunities for further research and development. This book can be used as a standard reference book and textbook in universities for Master and Doctoral students. The academic community relevant to the subject, namely faculty, researchers, scientists, and practicing engineers, will find the book both informative and as a useful source of successful case studies.

Book Synopsis Membranes for Membrane Reactors by : Angelo Basile
Download or read book Membranes for Membrane Reactors written by Angelo Basile and published by John Wiley & Sons. This book was released on 2010-12-20 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: A membrane reactor is a device for simultaneously performing a reaction and a membrane-based separation in the same physical device. Therefore, the membrane not only plays the role of a separator, but also takes place in the reaction itself. This text covers, in detail, the preparation and characterisation of all types of membranes used in membranes reactors. Each membrane synthesis process used by membranologists is explained by well known scientists in their specific research field. The book opens with an exhaustive review and introduction to membrane reactors, introducing the recent advances in this field. The following chapters concern the preparation of both organic and inorganic, and in both cases, a deep analysis of all the techniques used to prepare membrane are presented and discussed. A brief historical introduction for each technique is also included, followed by a complete description of the technique as well as the main results presented in the international specialized literature. In order to give to the reader a summary look to the overall work, a conclusive chapter is included for collecting all the information presented in the previous chapters. Key features: Fills a gap in the market for a scientific book describing the preparation and characterization of all the kind of membranes used in membrane reactors Discusses an important topic - there is increasing emphasis on membranes in general, due to their use as energy efficient separation tools and the ‘green’ chemistry opportunities they offer Includes a review about membrane reactors, several chapters concerning the preparation organic, inorganic, dense, porous, and composite membranes and a conclusion with a comparison among the different membrane preparation techniques
