This book was released on 1996 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL S'INSCRIT DANS LE CADRE DE LA MISE AU POINT DE PROCEDES DE TRAITEMENT DES EAUX USEES PEU COUTEUX ET ADAPTES AUX CONDITIONS TROPICALES. IL S'AGIT D'EVALUER L'INTERET DE PLANTES AQUATIQUES POUR L'ELIMINATION DES POLLUANTS ET DES MICROORGANISMES PATHOGENES. LA RECHERCHE A ETE CONDUITE EN 4 PHASES. LA PREMIERE CONCERNE L'ETUDE DE L'EVAPOTRANSPIRATION EN PRESENCE DE MACROPHYTES COMME PISTIA STRATIOTES ET TYPHA AUSTRALIS SE DEVELOPPANT SUR DES EAUX USEES. LA DEUXIEME EST RESERVEE A LA CONSTRUCTION ET LA MISE AU POINT D'UN DISTILLATEUR SOLAIRE COUPLE AVEC LA CULTURE DE TYPHA AUSTRALIS. UNE STATION EXPERIMENTALE D'EPURATION DES EAUX USEES A ETE CONSTRUITE DANS UN TROISIEME TEMPS AFIN D'ETUDIER LES ABATTEMENTS DES PARAMETRES PHYSICO-CHIMIQUES ET BACTERIOLOGIQUES. LE DISPOSITIF COMPORTE TROIS SYSTEMES D'EPURATION TERTIAIRE EN PARALLELE: 2 LAGUNAGES A MACROPHYTES (SALVINIA MOLESTA, LEMNA PAUCICOSTATA + CERATOPHYLLUM DEMERSUM) ET UN FILTRE A SABLE A MACROPHYTES ENRACINES SUIVI D'UNE ELECTROLYSE. ENFIN, LA QUATRIEME PHASE CONCERNE LA VALORISATION DE LA BIOMASSE PRODUITE, PAR COMPOSTAGE OU EN TANT QU'ALIMENT POUR VOLAILLES. LES RESULTATS MONTRENT QUE LA PRESENCE DE MACROPHYTES AUGMENTE L'EVAPORATION PAR RAPPORT A UNE SURFACE D'EAU NUE. LE DISTILLATEUR SOLAIRE A MACROPHYTES A PRESENTE DES PERFORMANCES PEU CONVAINCANTES EN RAISON DE LA FAIBLE POSSIBILITE DE MONTER EN TEMPERATURE ET DE DIFFICULTES A REFROIDIR LE CONDENSEUR. LES MACROPHYTES AUGMENTE L'ABATTEMENT DES PARAMETRES PHYSICO-CHIMIQUES DANS LE TRAITEMENT SECONDAIRE ET BACTERIOLOGIQUES DANS LE TRAITEMENT TERTIAIRE. LA BIOMASSE VEGETALE PRODUITE PEUT ETRE COMPOSTEE SEULE OU EN MELANGE. ELLE PEUT ETRE AUSSI UTILISEE COMME ALIMENT POUR L'ELEVAGE AVICOLE. EN CONCLUSION, L'UTILISATION DE MACROPHYTES DANS LE LAGUNAGE MONTRE UNE VOIE ADAPTEE POUR LE TRAITEMENT DES EAUX USEES EN MILIEU TROPICAL EN RAISON DES PERFORMANCES OBTENUES ET DES POSSIBILITES DE VALORISATIONS DE LA BIOMASSE ET DE L'EAU EPUREE

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
