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. The instructor's manual contains a description of the lesson, estimated presentation time, instructional materials list, suggested sequence of…

Capillary suction time is time required for the liquid phase of a treated sludge to travel through 1 centimeter of media (blotter or filter paper). Designed for individuals who have completed National Pollutant Discharge Elimination System (NPDES) level 1 laboratory training skills, this module provides waste water treatment plant operators with…

Designed for individuals who have completed National Pollutant Discharge Elimination System (NPDES) level 1 laboratory training skills, this module provides waste water treatment plant operators with the basic information needed to: (1) successfully run a centrifuge test; (2) accurately read results obtained in test tubes; and (3) obtain…

In the operation of vacuum filters and belt filters, it is desirable to evaluate the performance of different types of filter media and conditioning processes. The filter leaf test, which is used to evaluate these items, is described. Designed for individuals who have completed National Pollutant Discharge Elimination System (NPDES) level 1…

The rise time test (along with the settleometer procedure) is used to monitor sludge behavior in the secondary clarifier of an activated sludge system. The test monitors the effect of the nitrification/denitrification process and aids the operator in determining optimum clarifier sludge detention time and, to some extent, optimum degree of…

The settleometer test is used to indicate the solids-liquid separation (downtime) capability of sludge, most commonly on activated sludge entering the secondary clarifier and aerobic digesters. Designed for individuals who have completed National Pollutant Discharge Elimination System (NPDES) level 1 laboratory training skills, this module…

A commonly used test for determining filterability of conditioned sludge is the specific resistance (Buchner funnel) test. The sludge is filtered through filter paper using a Buchner funnel, and the time needed to obtain a given volume of filtrate (or for cake residue to begin to crack) is measured. The shorter the time, the better the…

The use of microteaching in Britain to train teachers of English as a second language is described. Microteaching is defined as a teaching encounter that is scaled down in terms of class sizes, lesson length, and teaching complexity. Based on visits and observations, the organization, content, goals, and components of British microteaching…

This annotated bibliography documents traditional isotonic strength training and nontraditional isotonic strength training (isokinetics) to aid the athletic coach in deciding which type and scheme of training will best develop strength. A glossary of terms is provided. Appendices include muscle action charts and tables, body position charts, a…

This conference collection presents 40 complete papers and abstracts of 33 project reports and 19 poster sessions, representing discussions of a variety of issues in the applications of computers to learning in business, industry, education, government, and the military services. A presentation on the conference topic "Courseware…

This study compares classroom management behaviors of two groups: beginning teachers and teachers with one year of teaching experience. It also examines differences in the ability of beginning teachers and second-year teachers to incorporate classroom management training in the establishment and maintenance of learning environments. The analysis…

The problems of meeting diverse needs, keeping training relevant, maintaining quality, minimizing administrative loads of course leaders, and keeping costs reasonable are discussed in this article dealing with the General Electric (GE) formen/supervisor program (FSP). Evaluation criteria for FSP course leaders and instructional modules are…

The authors promote the position that the benefits tend to exceed the pitfalls of dual facilitation of intense small group experience and should become a more standard feature of laboratory training, for reasons of new trainer development, better learning experience for participants, and continuing skill development of experienced trainers.
