Book Description
Véritable traité de référence et guide pratique, Principes fondamentaux du génie des procédés et de la technologie chimique répertorie et analyse les principes de base incontournables pour réaliser des synthèses industrielles de produits chimiques. Il présente également les fondements de la qualité, de la sécurité et de l'environnement, notions indispensables à maîtriser avant de mettre en route et de conduire un procédé. Organisé en 3 parties, cet ouvrage rassemble toutes les notions théoriques et pratiques nécessaires aux chimistes avant d'industrialiser un procédé physique ou chimique. Il permet : d'assimiler les théories et concepts fondamentaux impliqués dans les procédés (grandeurs physicochimiques, bilans de matière et d'énergie, équilibres physiques et chimiques, etc.), illustrés par 54 exercices d'application. Un chapitre est également consacré à la mise en oeuvre des opérations chimiques en présentant les connaissances de base sur les réacteurs chimiques idéaux et industriels, sur la qualité, la sécurité et l'environnement, d'acquérir une méthodologie efficace pour la conduite de calculs de base à travers 84 exercices et problèmes de synthèse résolus issus de situations industrielles réelles et de la pratique professionnelle. De difficulté croissante et commentés pas à pas, ces exercices permettent de progresser et de vérifier ses acquis, de savoir interpréter et maîtriser les opérations physiques et chimiques les plus courantes. Totalement inédite, cette partie reposant sur des déterminations expérimentales présente des exemples de bilans effectués dans des opérations de séparation ou de synthèse chimique réalisées à l'échelon pilote (rappel des notions théoriques, description exhaustive du matériel utilisé et des opérations à effectuer, présentation et interprétation des résultats expérimentaux…). Enrichie de 26 annexes rassemblant les principales données utilisées et de deux index détaillés, cette nouvelle édition constitue un support indispensable pour les étudiants et enseignants en génie des procédés et en chimie industrielle des IUT, STS, licences et masters professionnels ainsi que des écoles d'ingénieurs. Il sera également utile aux ingénieurs et techniciens supérieurs travaillant dans les domaines production et R&D de l'industrie chimique.

Book Description
This book preserves and scientifically interprets the African foreknowledge on water resources management. It offers insight into the relevance of the traditional knowledge and practices to modern approaches on sustainable water management. The African continent has partially preserved its natural habitat for centuries. In this book, this knowledge is combined with the current scientific understanding. The traditional practices are categorized as: i) water harvesting, ii) water transportation, iii) water storage and conservation, iv) water treatments, v) myths and folk stories about water management or conservation, vi) water resource management systems, and vii) soil–water–forest conservation/management systems sub-topics. The findings presented here are in line with SDG 6, which aims at ensuring availability and sustainable management of water and sanitation for all by the year 2030.

Book Description
In most of the developed countries of the,World, significant efforts to control the pollution of surface waters have been underway for decades, and particularly the last 10-15 years. These efforts have focused mainly on eliminating or mitiga ting the effects of point sources of pollution. In many ca ses, however, it is clear that we have achieved only limited improvement in water quality, and that non-point sources of pollution are going to control any further improvement. It has long been known that urban runoff is a major non-point source, and much research has been done in an attempt to un derstand the mechanisms and processes which govern this source and to reduce or eliminate its impacts. Many urban jurisdic tions have adopted urban runoff pollution control measures, in spite of the fact that there is a great deal that we still do not know, and without really being able to quantify the benefits achieved. A major problem is that while a great deal of work is being done, both in Europe and North America, it is very difficult to keep abreast of new developments. The Urban Water Resources Research Council of the American Society of Civil Engineers has for many years had as one of its major objectives the transfer of urban runoff technology among researchers and practitioners in the field, as well as to those engineers who are not in the forefront but who nonetheless need the information on the latest developments.

Book Description
Selenium (Se) pollution has led to several cases of severe aquatic ecosystem deterioration due to Se poisoning caused by bioaccumulation over time. However, the removal of selenate (SeO42-) from wastewater streams with co-contaminants has been largely considered as a black box in anaerobic biological systems using mixed consortia. This research aimed at addressing the effect of wastewater characteristics, i.e. co-contaminants such as nitrate (NO3-) and sulfate (SO42-), heavy metals and pH, on the biological reduction of SeO42- and evaluating process integration for Se-laden wastewater treatment with co-contaminants. This study demonstrated that the presence of co-contaminants can actually be beneficial for Se removal provided that the concentrations are carefully monitored and appropriate operating conditions and process configurations are used. The Se removal (total Se and SeO42-) efficiency increased by ~30% in the presence of NO3- and/or SO42- compared to systems with SeO42- alone. Additionally, an integrated process of an ion exchange (IX) column and bioreactors showed improved overall removal capacity for SO42- and total Se. The knowledge and information gained from this research can help in the advancement and application of biological processes, i.e. predicting of reactor performance, solving specific design or practical problems and implementing novel treatment techniques for Se-laden mine wastewater.
