Innovative and alternative methods of wastewater treatment can improve the efficiency and lower the cost of waste treatment procedures. Described in this instructor's guide is a one-hour learning session for citizens interested in improving water quality planning and decision making. Among the topics covered are the need for alternative wastewater…

Reports that there are currently three companies that own mobile physical-chemical wastewater treatment vans that investigate such parameters as chemical coagulation, sedimentation, sand filtration and carbon adsorption. Information is provided regarding the potential of utilizing this type of facility and rental agreements. (MLB)

The costs and performance of contract management of municipal wastewater treatment facilities are considered, using information from a nationwide empirical examination of evidence from individual plants, municipalities, and regulatory agencies. The broad issues arising in the evaluation are outlined as the specifics are discussed. (SLD)

A sampling plan is devised for monitoring air pollution emissions from a typical municipal wastewater treatment plant. (Author/BB)

This instructor's manual provides an outline and guide for teaching Wastewater Treatment I. It consists of nine sections. An introductory note and a course outline comprise sections 1 and 2. Section 3 (the bulk of the guide) presents lesson outlines for teaching the ten chapters of the manual entitled "Operation of Wastewater Treatment…

Discusses an experimental program to help solve the problems of securing and training new technicians for wastewater treatment facilities. (CS)

How state agencies have addressed privatization in a service setting (municipal wastewater treatment) is discussed. The implications for evaluations of many types of programs, particularly those of local service programs regulated by the states, are explored. Data from a national survey of state environmental regulatory agencies are highlighted.…

Some simple chemistry is used to demonstrate how Fe(II) ions, formed during iron corrosion in acid aqueous solution, can reduce toxic Cr(VI) species, forming soluble Cr(III) and Fe(III) ions. These ions, in turn, can be precipitated by neutralizing the solution. The procedure provides a treatment for industrial wastewaters commonly found in…

Ten case reports of agricultural uses of thermally conditioned wastewater treatment sludge are given to show a way of recycling wastes. (MR)

This article discusses training programs for environmental technicians at wastewater treatment facilities. Special attention is given to start-up orientation and training. (CS)

This manual provides guidance for putting into initial operation a new municipal wastewater treatment plant, a new addition to an existing treatment plant, or a change in the mode of a treatment plant's operation. Information is provided on preparing for actual treatment plant start-up. Preparation for start-up includes: staffing the plant,…

Reported are a literature survey and laboratory data which investigate modified coagulation as a method for organics removal in water and wastewater treatment. (CS)

Introduces the Living Machine at Darrow School which is an ecological design for wastewater treatment. Uses the facility as an interdisciplinary curriculum component. (YDS)

A discussion of a proposed program for a national standardized water and wastewater treatment certification is presented. A modular certification exam outline is included. (MR)

Presented are the recommendations of the Water Pollution Control Federation for operation and maintenance consideration during the planning design, construction, and operation of wastewater treatment facilities. (CS)
