This training manual provides information needed to meet the minimum EPA standards for certification as a commercial applicator of pesticides in the right-of-way pest control category. The text discusses types of vegetation, the nature of herbicides, application methods, use for specific situations, and safety precautions. (CS)

This booklet is for wastewater treatment plant operators who find it difficult to follow the detailed discussions and procedures found in "Standard Methods for the Examination of Water and Wastewater." It is intended to be used with "Standard Methods" available for reference. Included in this publication are chapters on…

This guide describes standard operating job procedures for the digestion process of wastewater treatment facilities. This process is for reducing the volume of sludge to be treated in subsequent units and to reduce the volatile content of sludge. The guide gives step-by-step instructions for pre-startup, startup, continuous operating, shutdown,…

This guide describes standard operating job procedures for the sludge conditioning and dewatering process of wastewater treatment facilities. In this process, sludge is treated with chemicals to make the sludge coagulate and give up its water more easily. The treated sludge is then dewatered using a vacuum filter. The guide gives step-by-step…

This manual presents a procedure for the design of land treatment systems. Slow rate, rapid infiltration, and overland flow processes for the treatment of municipal wastewaters are given emphasis. The basic unit operations and unit processes are discussed in detail, and the design concepts and criteria are presented. The manual includes design…

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 manual for industrial wastewater monitoring covers the philosophy of monitoring needs, planning, sampling, measuring, and analysis. Sufficient detail is given for those who wish to explore more deeply some of the practical and theoretical aspects of any of the phases of a monitoring program. A logical procedure is suggested and direction…

This manual attempts to describe new treatment methods, and discuss the application of new techniques for more effectively removing a broad spectrum of contaminants from wastewater. Topics covered include: fundamental design considerations, flow equalization, headworks components, clarification of raw wastewater, activated sludge, package plants,…

This study guide contains typical questions and answers that all levels of water treatment plant operators might expect to find on a certification examination. The manual covers the basic sciences, treatment techniques, testing procedures, and federal legislation. (Author/SB)

This manual presents theoretical and process design criteria for the implementation of nitrogen control technology in municipal wastewater treatment facilities. Design concepts are emphasized through examination of data from full-scale and pilot installations. Design data are included on biological nitrification and denitrification, breakpoint…
