Описание: In this collection, the authors report on the pretreatment methods for waste activated sludge based on pulsed electric field and corona discharge techniques. The effects of pulse magnitude, frequency, temperature and pretreatment time are demonstrated on the basis of cell membrane electroporation. The influence of voltage polarity, frequency, magnitude, treating time and temperature has also been demonstrated. A description of fundamental techniques in molecular biology for the analysis of the microbiota of activated sludge is provided. Activated sludge is a heterogeneous system of organisms, organic and inorganic material, and therefore giving a specific protocol for each molecular technique would be imprudent. The authors go on to discuss the Monod model, which provides a functional relationship between specific growth rate and substrate concentration in the bulk. Important research efforts dedicated to adequate use of the Monod model are presented, consolidating knowledge from activated sludge and biofilm modelling, identifying misdirections, and setting parameters for further research. In one study, different microwave power outputs and times were optimised for sludge solubilisation without evaporation loss in waste activated sludge from two different sources. The variable effects of pre-treatments on extracellular polymeric substances fraction, cellular oxidative stress and solubilisation of both sludges were evaluated to understand the impact of sludge complexity. The penultimate chapter examines how toxic carbon sources can cause higher residual effluent dissolved organic carbon than easily biodegraded carbon sources in the activated sludge process. Based on the variations of chemical components of activated sludge, mainly intracellular storage materials, extracellular polymeric substances and soluble microbial products, the performance and mechanism of toxic carbon on the activated sludge process can be clarified. The purpose of the final study is to research the supplementation of different concentrations of substrate on the degradation rate of xenobiotics, and to determine the optimal concentrations of auxiliary substrates that are most beneficial. The results show that sugar and peptone can affect 2,4-D degradation rate by several different degrees at different concentrations.

Описание: This book highlights the importance of molecular genomics and molecular biology techniques used to sort out the problems faced by industrialists who operate wastewater treatment plants with the ever-increasing number of environmental pollutants, through an approach of microbial community analysis. Current knowledge of the microbial communities within biological wastewater treatment reactors is incomplete due to limitations of traditional culture-based techniques and despite the emergence of recently applied physico-chemical and biological techniques. This book will give a complete overview about an advanced molecular technology for microbial community analysis of a wastewater treatment reactor to understand and gain proper knowledge, which may help to ultimately sort out the issue of environmental pollutants. It will give an insight about an application of various molecular tools to investigate microbial community composition or structure in activated sludge processes.

Описание: This book introduces the use of bio-waste as a raw material for the preparation of activated carbon (AC) for dyes removal. Activated carbon was derived from assorted materials that have potential to function as a good adsorbent, especially for dyes removal in wastewater treatment. This book was written as a case study to help readers understand the function of AC in each system and approach. This book includes applications of AC derived from corncob; palm tree empty fruit bunch; seashell; eggshell; spent coffee ground; rubber wood saw dust; kenaf fiber and coconut frond in dyes removal and wastewater treatment. The efficiency of activated carbon prepared from various bio-wastes is evaluated by calculating the removal rate of dyes in wastewater. This unique book features eight chapters pertinent to the current situation, as loads of dye effluent are being discharged into the environment. The characterization of the produced AC is analysed using various instrumentations such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIRS) and X-ray diffraction (XRD). The book will attract Eastern and Western researchers and scholars at all levels of degree qualification, industrial practitioners and entrepreneurs in the field of bio-waste.

Converting sludge into construction materials is deemed to be a sustainable approach to alleviating sludge disposal problems and conserving natural resources.
This compendium presents the state-of-the-art development in recycling sludge into construction materials. A research-based development of engineering products made from sludge for common construction applications such as bricks, aggregates and cement-replacement materials is outlined. In-depth discussions on the properties of the products and their processing technology, the technical suitability for construction applications, and experimental study and assessment of toxic or hazardous chemicals leached from the products are prominently highlighted. Challenges and prospect of sludge recycling are also included.
Contributed by eminent authors who are recognized authority in the field of sludge treatment and reuse, the unique monograph is a useful reference guide for professionals, researchers, academics and graduate students majoring in waste management, environmental engineering, civil engineering and materials engineering.
