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. 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 technique of computer simulation applied to collective bargaining situations is presented in the setting of negotiations between library administration and staff (representing, respectively, management and labor union). The negotiation simulation exercise was developed for use in both college and industry. (MF)

Describes a training program in human relations for camp directors. Intended for groups of 8 to 12 people over 15 to 20 hours of group time. Lists topics for discussions about group process. Addresses participant concerns about feelings generated by workshop activities. Provides 22 references for experiential learning. (CS)

Description of the Child Development Associate (CDA) program is provided in terms of goals, characteristics, and training procedures, as well as future directions. (MP)

Elaborates Kohlberg's six stages of moral development and applies this theory to a course to train union stewards for processing grievances. Discusses other applications in labor education. (SK)

Training Extension Course (TEC) system, based on individual, performance-oriented achievement, represents a revolution in Army training concepts and practices. It involves using measurable behavioral objectives, criterion-referenced testing, and validated training materials. (JOW)

A 1996 survey of U.S. and Canadian lifeguards examined their behaviors, training, and abilities. The data revealed that lifeguards did not always follow many of the acceptable or established standards in the field. Though lifeguards felt well trained, 100 of 2,281 did not feel confident about making a water rescue. (SM)
