Intended for persons associated with wastewater treatment plant operations and management (O&M), the course described is designed to address significant factors contributing to poor plant performance. The training materials discuss the interaction between several potential causes of problems and stress the need for comprehensive corrective…

This is the first in a series of documents developed by the National Training and Operational Technology Center describing operational control procedures for the activated sludge process used in wastewater treatment. Part I of this document deals with physical observations which should be performed during each routine control test. Part II…

This learning module is designed to integrate environmental education into ninth- and tenth-grade chemistry classes. This module and a companion social studies module were pilot tested in Gwinnett County, Georgia in 1975-76. The module is divided into four parts. Part one provides a broad overview of unit content and proposes questions to…

This guide describes standard operating job procedures for the screening and grinding process of wastewater treatment facilities. The objective of this process is the removal of coarse materials from the raw waste stream for the protection of subsequent equipment and processes. The guide gives step-by-step instructions for safety inspection,…

This guide describes the standard operating job procedures for the tertiary chemical treatment - lime precipitation process of wastewater treatment plants. Step-by-step instructions are given for pre-start up, start-up, continuous operation, and shut-down procedures. In addition, some theoretical material is presented along with some relevant…

This guide describes the standard operating job procedures for the tertiary multimedia filtration process of wastewater treatment plants. The major objective of the filtration process is the removal of suspended solids from the reclaimed wastewater. The guide gives step-by-step instructions for pre-start up, start-up, continuous operation, and…

Instructions for using the Huntington II Simulation Program - POLUT are contained in this resource handbook. POLUT is a program written in BASIC which provides simulation of the interaction between water and waste. It creates a context within which the user can control specific variables which affect the quality of a water resource. The output is…

The objective of a two-day Symposium on Systems Approach to Environmental Pollution of the Operations Research Society of America at the 137th Annual Meeting of the American Association for the Advancement of Science, December 27-28, 1970 in Chicago, Illinois, was not to raise the litany of a systems approach as the answer to all environmental…

This publication was prepared as a guideline for citizens of Alabama who want to improve the environment of their state. This booklet includes 200 suggestions for improving the environment. These suggestions are divided into the following sections: (1) Our Ailing Air; (2) Our Ailing Earth; (3) Our Ailing Water; and (4) What Else You Can Do. The…

Working with the United Nations Development Program, the Mexican government's Program for Environmental Improvement is planning, coordinating, operating and monitoring pollution abatement programs in the areas of air, water, solid waste and pesticides. A brief discussion of activities is given. (BT)
