Many industrial, power generation and chemical processes produce unwanted fine particulate material as a consequence of their operation. Electrostatic precipitation is a highly efficient method of removing entrained particulate contaminants from exhaust gases and is extensively used in these industries to limit particulate emissions. New legislation aimed at improving the environment by further limiting these discharges has resulted in the technique undergoing considerable development over the past decade, to the point where it has become the method of choice, over a wide range of applications, for limiting particulate discharges. In this new book, the editor has brought together an international team of contributors, mainly industrialists and consultants, to produce an authorative and practical guide to electrostatic precipitation. This book is of interest to all those in process industries or power generation and to academics concerned with gas cleaning and environmental issues.

"Electrostatic Precipitation" includes selected papers presented at the 11th International Conference on Electrostatic Precipitation. It presents the newest developments in electrostatic precipitation, flue gas desulphurization (FGD), selective catalytic reduction (SCR), and non-thermal plasma techniques for multi-pollutants emission control. Almost all outstanding scientists and engineers world-wide in the field will report their on-going researches. The book will be a useful reference for scientists and engineers to keep abreast of the latest developments in environmental science and engineering.

This book identifies the physical and engineering basis for the development of electrical equipment for electrostatic precipitators and thoroughly explores the technological factors which optimise the efficiency of the precipitator and hence minimise emissions, as well as future developments in the electrical field.

Particle separation from hot gases is a challenging task, especially for nanoparticles. Therefore, it is usually avoided by quenching the hot gas to conduct particle separation at a more convenient temperature. In these cases, valuable high-caloric heat is either not utilized at all or only inefficiently because of particle deposition on the heat exchanger surfaces. Valuable potential is thus wasted, as high-temperature processes are already an essential part of many industries and become increasingly relevant for other industrial sectors (e.g., pyrolytic processes in the circular economy). To reduce operating costs and environmental impact, the efficient use of resources (especially fossil fuels) is an absolute necessity. To tackle this pending problem, the concept of high-temperature electrostatic precipitation is investigated in this doctoral thesis. In an electrostatic precipitator, particles are charged by charge carriers produced in a corona discharge near the discharge electrode. Charged particles migrate due to the electric field and subsequently precipitate onto the collection electrode. This doctoral thesis clearly demonstrates the feasibility of nanoparticle removal from hot gases at up to 1073 K (800 °C) using electrostatic precipitation while presenting novel insights into the charge carrier properties and their distribution, the influence of thermionic emission on the operation of electrostatic precipitators, and the fundamentals of particle charging at high temperatures.

This present book includes selected papers presented at the 16th International Conference on Electrostatic Precipitation. It presents research shortcomings and future orientations in ESP among others, advancements in power supply, modelling, novel applications and new techniques, industrial experience and case studies. Outstanding scientists and engineers worldwide in the field reported their on-going researches. The book is a useful reference for scientists and engineers to keep abreast of the latest developments in environmental science and engineering.

Environmental engineering has a leading role in the elimination of ecological threats, and can deal with a wide range of technical and technological problems due to its interdisciplinary character.

This book highlights the several pollutants and their derivatives that exist in water and wastewater, such as pharmaceuticals, antibiotics, personal care products, heavy metals, pesticides, dyes etc., as a result of rapid urbanization and industrialization. Several part pollution is caused by nutrients, organics, and contaminants with low concentration but is highly toxic to human and aquatic environment. This book provides a holistic approach in terms of measurement, monitoring, and recent advances in treatment technologies for water and wastewater treatment and water reuse. The technologies involve the physio-chemical, biological and advanced oxidation processes in which they are modified or coupled with nanomaterials and/or newly developed products for improving the performance of the current treatment processes. In addition, the membrane processes include recent research on the removal of challenging chemicals by various membrane bioreactors and reverse osmosis processes.

This book provides new clues for understanding electrostatic charging in solids and liquids, resulting from the surge of research in this active area of science that is taking place since the 1990's but is still largely unknown to most researchers, lecturers and engineers. Written by a leading researcher in this field, this book describes the formation and properties of the Earth capacitor, the production of environmental electricity and its effect on natural and anthropic systems and examines many situations in which water may play a decisive role in electrostatic behavior. The authors present an informed critique of the long-held assumption that pure substances should be electroneutral. In this regard, the authors show that charge partition and accumulation is expected considering the electrochemical potential under non-zero electrostatic potential, which prevails at Earth surface. This book provides conceptual tools to guide the reader through the complexities and consequences of electrostatic phenomena while covering exciting current topics such as energy scavenging from the environment, electrostatic based green production, energy-saving processes, electrochemistry at the solid-gas interface, therapeutic electrostatic treatments, applications in sanitation and pest control and control of atmospheric electricity and its use in climate engineering.

This book introduces comprehensive fundamentals, numerical simulations and experimental methods of electrification of particulates entrained multiphase flows. The electrifications of two particulate forms, liquid droplets and solid particles, are firstly described together. Liquid droplets can be charged under preset or associated electric fields, while solid particles can be charged through contact. Different charging ways in gas (liquid)-liquid or gas-solid multiphase flows are summarized, including ones that are beneficial to industrial processes, such as electrostatic precipitation, electrostatic spraying, and electrostatic separation, etc., ones harmful for shipping and powder industry, and ones occurring in natural phenomenon, such as wind-blown sand and thunderstorm. This book offers theoretical references to the control and utilization of the charging or charged particulates in multiphase flows as well.
