Water and Wastes Engineering, 1978
Describes a large-scale bio-conversion facility that will produce methane gas from raw manure. An innovative feature of the plant will be an algae farm/water recycling unit. (Author/MA)
Descriptors: Energy, Fuels, Natural Resources, Recycling
Smith, James W. – Water and Wastes Engineering, 1978
Gives a comparative study of disinfectants used to rid wastewater of pathogens. Concentrates on the effects of chlorine and ozone, with some mention of ultra-violet irradiation, bromine chloride, and chlorine dioxide. (MA)
Descriptors: Chemistry, Health, Natural Resources, Wastes
Dalton, Frank E.; La Russo, Ramon S. – Water and Wastes Engineering, 1979
This is the third, concluding, part of an article on the Greater Chicago Tunnel and Reservoir Plan (TARP). It focuses on the hydrologic and hydraulic studies which controlled the sizing of tunnels, storage reservoirs and pumping stations, and on the resulting pumping station and reservoir. (BB)
Descriptors: Construction Programs, Engineering, Environment, Technology
Gustafson, George D. – Water and Wastes Engineering, 1979
The small coastal city of Rockland, Maine solved its pollution problems by building a treatment plant to handle the combined domestic and industrial wastewaters that were being discharged into Rockland Harbor. (BB)
Descriptors: Environment, Industry, Pollution, Science Education
Davanzo, A. C.; Thompson, William B. – Water and Wastes Engineering, 1978
Describes is an improvement program for the operation and maintenance of municipal wastewater treatment plants in Detroit, Michigan. Improvements included expansion and upgrading of the existing city plant and a training program for plant personnel. (MA)
Descriptors: Educational Programs, Environment, Natural Resources, Program Descriptions
Water and Wastes Engineering, 1978
Responses of two experts to questions concerning wastewater plant operation and maintenance are presented. The responses discuss the scarcity of good personnel, training education available, and examples of existing improvement projects. (MA)
Descriptors: Environment, Interviews, Maintenance, Natural Resources
Wert, Frank S.; Henderson, Upton B. – Water and Wastes Engineering, 1978
Discusses the ways in which aquaculture can be a cost-effective wastewater treatment alternative. Fifteen strategies were selected as being appropriate and technologically feasible wastewater treatment systems to compare for the size of community under consideration. Costs for each stage of each strategy were estimated and compared. (Author/MA)
Descriptors: Biology, Cost Effectiveness, Ecological Factors, Natural Resources
Simek, Edward M., Jr. – Water and Wastes Engineering, 1979
The study reported on here determines temperature, salinity, and current data, and surveys complex interactions between the thermal plume and the Delaware River. (BB)
Descriptors: Data, Environmental Research, Pollution, Rivers
Hart, Edward C. – Water and Wastes Engineering, 1978
Programs for calculating gravity flow using a Texas Instruments SR-52 and the Programmed Manning Equation are given and discussed. (MR)
Descriptors: Calculators, Computation, Instructional Materials, Mathematical Applications
Carmichael, Gregory M. – Water and Wastes Engineering, 1978
This article profiles sewage treatment plant operators in northern California and common problems such as pay, self-esteem, and lack of public recognition of operators in general. The information gained can be helpful in curriculum and program development, as a rationale for affirmative action, or as a basis for additional studies. (CS)
