Book Synopsis Faecal Sludge Management by : Linda Strande
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.

Book Synopsis Ecosystem Function in Heterogeneous Landscapes by : Gary M. Lovett
Download or read book Ecosystem Function in Heterogeneous Landscapes written by Gary M. Lovett and published by Springer Science & Business Media. This book was released on 2005-12-15 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking work connects the knowledge of system function developed in ecosystem ecology with landscape ecology's knowledge of spatial structure. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management.
Book Synopsis How to Design Wastewater Systems for Local Conditions in Developing Countries by : David M. Robbins
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.

This book was released on 1996 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: LES EAUX SOUTERRAINES EXPLOITEES SONT SOUVENT PEU PROFONDES ET FACILEMENT ACCESSIBLES AUX POLLUTIONS, NOTAMMENT AUX NITRATES. IL EST DONC IMPORTANT D'ETUDIER LA FACILITE TECHNIQUE DE SYSTEMES SIMPLES ET PEU COUTEUX DE DENITRIFICATION BIOLOGIQUE IN SITU, DE NAPPES PHREATIQUES. DANS LE CAS PRESENT, L'AQUIFERE CRAYEUX A ETE POLLUE PAR DES INFILTRATIONS EN PROVENANCE D'UNE USINE D'ENGRAIS AZOTES. L'ACQUISITION DE PARAMETRES PHYSICO-CHIMIQUES ET BIOLOGIQUES DANS LA ZONE D'ETUDE, A MONTRE DE FORTES TENEURS EN NITRATES (PARFOIS SUPERIEURES A 1500 MG/L), UNE FAIBLE POPULATION BACTERIENNE ET L'ABSENCE DE SUBSTRAT CARBONE DISPONIBLE POUR CES MICRO-ORGANISMES. LORS D'ESSAIS DE REPRODUCTION DE L'ECOSYSTEME NATUREL, EN REACTEURS-PILOTES A BIOFILMS FIXES SUR DES SUPPORTS MINERAUX, UNE DENITRIFICATION BIOLOGIQUE RAPIDE S'EST MISE EN PLACE. L'APPORT OPTIMAL EN CARBONE ORGANIQUE EST DETERMINE EGAL A 0,8-1 G DCO/G NO3 A ELIMINER. L'ADDITION DE METAUX A REDUIT LA CONCENTRATION RESIDUELLE EN NITRITES DE 80 A 98% ET AUGMENTE LE RENDEMENT DE DENITRATATION DE 95 A 98%. PAR AILLEURS, L'ETUDE EN CULTURE PURE D'ALCALIGENES DENITRIFICANS ET UNE SOUCHE H A CONFIRME L'INCIDENCE, DANS LE PROCESSUS DE DENITRITATION, DES ELEMENTS METALLIQUES DES LES TRES FAIBLES CONCENTRATIONS (INFERIEURES A 0,1 MG/L). LA MISE EN PLACE D'UNE INSTALLATION PILOTE DE TERRAIN DEVRA INTEGRER LES RESULTATS DE LABORATOIRE, ET PARTICULIEREMENT LE CHOIX DU SYSTEME NUTRITIF POUR LES MICRO-ORGANISMES (CARBONE, PHOSPHORE ET METAUX)
