International Water Association
Join the IWA
The International Water Association (IWA) is a water/wastewater organization I highly recommend you join. As a member you have access to a wide range of excellent textbooks at discounted pricing. I've purchased many books from the IWA. In addition, they have numerous technical publications/magazines that you get online access to as a member.
As an example of the outstanding reference information available from the IWA I am providing you with links to six wastewater textbooks, as PDF files, downloaded for free from the IWA.
Wastewater Characteristics, Treatment and Disposal—Volume 1 of 6
Wastewater Characteristics, Treatment and Disposal is the first volume in the series Biological Wastewater Treatment, presenting an integrated view of water quality and wastewater treatment. The book covers the following topics:
Wastewater characteristics (flow and major constituents),
Impact of wastewater discharges to rivers and lakes,
Overview of wastewater treatment systems, and
Complementary items in planning studies.
This book, with its clear and practical approach, lays the foundations for the topics that are analyzed in more detail in the other books of the series.
Basic Principles of Wastewater Treatment—Volume 2 of 6
Basic Principles of Wastewater Treatment is the second volume in the series Biological Wastewater Treatment, and focuses on the unit operations and processes associated with biological wastewater treatment. The major topics covered are:
Microbiology and ecology of wastewater treatment,
Reaction kinetics and reactor hydraulics,
Conversion of organic and inorganic matter,
The theory presented in this volume forms the basis upon which the other books of the series are built.
Waste Stabilization Ponds—Volume 3 of 6
Waste Stabilization Ponds is the third volume in the series Biological Wastewater Treatment. The major variants of pond systems are fully covered, namely:
Aerated lagoons, and
The book presents in a clear and informative way the main concepts, working principles, expected removal efficiencies, design criteria, design examples, construction aspects, operational guidelines and sludge management for pond systems.
Anaerobic Reactors—Volume 4 of 6
Anaerobic Reactors is the fourth volume in the series Biological Wastewater Treatment. The fundamentals of anaerobic treatment are presented in detail, including its applicability, microbiology, biochemistry and main reactor configurations. Two reactor types are analyzed in more detail, namely anaerobic filters and especially UASB (upflow anaerobic sludge blanket) reactors. Particular attention is also devoted to the post-treatment of the effluents from the anaerobic reactors. The book presents in a clear and informative way the main concepts, working principles, expected removal efficiencies, design criteria, design examples, construction aspects and operational guidelines for anaerobic reactors.
Activated Sludge and Aerobic Biofilm Reactors—Volume 5 of 6
Activated Sludge and Aerobic Biofilm Reactors is the fifth volume in the series Biological Wastewater Treatment. The first part of the book is devoted to the activated sludge process, covering the removal of organic matter, nitrogen and phosphorus. A detailed analysis of the biological reactor (aeration tank) and the final sedimentation tanks is provided. The second part of the book covers aerobic biofilm reactors, especially trickling filters, rotating biological contractors and submerged aerated biofilters. For all the systems, the book presents in a clear and informative way the main concepts, working principles, expected removal efficiencies, design criteria, design examples, construction aspects and operational guidelines.
Sludge Treatment and Disposal—Volume 6 of 6
Sludge Treatment and Disposal is the sixth volume in the series Biological Wastewater Treatment. The book covers in a clear and informative way the sludge characteristics, production, treatment (thickening, dewatering, stabilization, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are also fully described.
