Available in PDF, EPUB and Kindle. Book excerpt: While the treatment of water and exhaust gas using ultraviolet (UV) light offers both ecological and economic advantages, information on photo-initiated advanced oxidation technologies (AOTs) has been dispersed among various journals and proceedings until now. This authoritative and comprehensive handbook is the first to cover both the photochemical fundamentals and practical applications, including a description of advanced oxidation processes (AOPs) and process engineering of suitable photoreactors. The author presents various real-world examples, including economic aspects, while many references to current scientific literature facilitate access to current research topics relevant for water and air industries. Throughout, over 140 detailed figures visualize photochemical and photophysical phenomena, and help in interpreting important research results. From the foreword by James R. Bolton (President of Bolton Photosciences Inc., Executive Director of the International Ultraviolet Association (IUVA)): "Prof. Oppenländer is well qualified to write about the AOPs/AOTs, since he has contributed to this literature in a very significant manner. This book will be of considerable value to graduate students, science and engineering faculty, scientists, process engineers and sales engineers in industry, government regulators and health professionals."

This book was released on 2013-06-10 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the optimization of photochemical reactors for the production of hy-droxyl radicals which can be used in advanced oxidation processes for water purification. Minimization of the energy cost of the applied UV-lamp(s) is possible via a modelbased optimization of the reactor geometry. To this end, 2D reactor models are first built taking into account balance equations, reaction kinetics, reactor geometry and radiation intensity. Two tubular reactor configurations with cylinder-shaped UV-lamps are studied: a single-lamp reactor with only one lamp located at the reactor axis and a multi-lamp reactor in which the lamps are positioned symmetrically in a circular pattern. Afterwards well-posed optimization problems are formulated. For given values of the reactor volume, the flow of water to be treated and the radiation power of the UV-lamps, the aim is to minimize the average concentration of an organic pollutant at the reactor outlet. For the single-lamp reactor the optimal reactor diameter is computed, while for the multi-lamp reactor the optimal location of the lamps in the radial direction is calculated. From the results, it follows that an optimal reactor diameter (and length) exists for the single-lamp reactor (and for the multi-lamp reactor). For the multi-lamp reactor, an optimal lamp position exists. It has been shown that for the latter reactor an optimal number of lamps exists, trading off an improved radiation intensity uniformity and a decreased radiation penetration due to a lower radiation power per lamp.

"A certain amount of energy destroys the same amount of CO2 according to the whether it is administered continuously or intermittently. In order to rationalize this result there are two possibilities, either the destruction of CO2 further occurred in the dark periods, which would lead to the same form of energy storing form, or in the illuminated period the reaction goes at twice the rate." O. Warburg, Biochem. Z., 1919, 100, 230-270.

Download or read book Photo and Electrochemical Water Treatment written by Halan Prakash and published by Royal Society of Chemistry. This book was released on 2022-12-21 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, 2.1 billion people live without access to safe water, and about 159 million people collect their drinking water directly from surface water sources. This issue is particularly prominent in water-stressed areas, such as India, which has a rural population of around 700 million, 63 million of whom do not have access to clean water. Contaminants of Emerging Concern (CECs), of both a chemical and biological nature, are increasingly being detected in wastewater effluents around the world. Chemical CECs include pollutants such as pharmaceuticals and personal care products, pesticides, hormones, and endocrine disruptors, and biological CECs include antibiotic resistant bacteria, pathogenic protozoans, and viruses. New technologies to remove the contaminants from water are urgently needed and photochemical approaches offer an exciting array of possibilities. Covering chemical analysis, molecular biology methods and computational approaches important for the elucidation of mechanisms and evaluation of photochemical processes, this book presents advanced photochemical processes for the removal of CECs from water. Readers will find chapters on advanced photochemical treatment prototypes and pilot plants, and discussions on translation from lab to field-scale implementation. Examples include highly transparent materials, integrated membranes, adsorbents, and photocatalysts for enhancing the photochemical processes by direct sunlight induced reactions, photo-Fenton, and photo-electrochemical reactions. Discussing both the advantages and disadvantages of these technologies, this book is a great resource both for academics researching photocatalytic processes and for water treatment professionals.
