Today's industrial economies were founded on the use of vast quantities of materials and energy, and the economic health of nations has often been equated with the amount they consumed. The amount of materials that originally enters an economy tells nothing about the material's eventual fate or its contribution to human well-being. It tells a good…

This lesson, an introduction to belt management, was developed for a course in sludge treatment and disposal. Fundamental principles of belt filter operation are described. Chemical conditioning and the effect on sludge characteristics are discussed, and a detailed description of the different zones of dewatering is presented. Information on…

Composting is a lesson developed for a sludge treatment and disposal course. The lesson discusses the basic theory of composting and the basic operation, in a step-by-step sequence, of the two typical composting procedures: windrow and forced air static pile. The lesson then covers basic monitoring and operational procedures. The instructor's…

Laboratory tests used to determine status and to evaluate and/or maintain process control of the various sludge treatment processes are introduced in this lesson. Neither detailed test procedures nor explanations of how the tests should be applied to every unit are explained; this information is provided in other modules. The instructor's manual…

This lesson is an introduction to the operation of filter presses. Two basic types of presses, their components, the sequence of operation, operational controls, sampling, and testing are discussed.
