Completely revised - peer reviewed -- the complete authority! This second edition of Activated Sludge, MOP OM-9, represents the most complete information source for the activated sludge process. Well-established design standards based on empirical data have evolved over the years. Despite these advances, poor process performance can still be present problems for many plants. The objective of this manual is to help wastewater professionals acquire a greater knowledge of the process, solve performance problems, and improve operations. This manual serves as the Federation’s primary reference for

Mathematical modeling is a useful tool for the design, analysis and control of wastewater treatment systems. The activated sludge process is one of the most common processes used in wastewater treatment, and therefore is a particularly important candidate for the application of mathematical models. In the 1980s, a task group organized by the International Association on Water Quality (IAWQ) developed a conceptual model of the activated sludge process, which has become an industry-wide standard for the development of computer-based activated sludge models. A recent version of the IAWQ model inc

The guidelines show how national governments can plan, develop, implement and monitor a national programme on sustainable consumption and production (SCP). This is a flexible approach to SCP programme development which will be adapted to local circumstances. The guidelines are also useful to countries that already have a SCP programme but are keen to improve and sustain the process. They contain nine case studies and several other examples of good practice, which illustrate how governments are implementing SCP programmes all over the world.
