摘要:

This letter presents corrections to “Organic Halogen Measurements: Current Uses and Future Prospects” which appeared in the April 1985 issue of Journal AWWA. The column heading “Volatiles” should be transposed with the column heading “Nonvolatiles” and in the column entitled “Analytical Method”, the entry “LLE‐BG” should read “LLE‐GC”.

摘要:

The New Jersey Department of Environmental Protection adopted a fee schedule for a permit system to regulate discharges of pollutants into surface waters, under which volume‐based formulas yielded the individual fees for permittees within each category. When a group of electric utilities challenged the permit fees. a trial court upheld the thermal fees. In an appeal, the utilities stated argued that the law mandated that the state institute a fee program that would cover the costs of processing the permits and that only the demonstrated costs could be recovered from individual permit holders. The court said it was not necessary for the department to determine the costs attributable to each individual license and stated that there was ample support for a fee‐based regulatory system that related costs of graduated differences in amounts discharged.

摘要:

The question of whether or not it is feasible for utilities in the United States and Canada to fund an industry research program through voluntary subscription was discussed at the AWWA Annual Conference in Washington, D.C., June 25, 1985. Participants were: Fred Elwell, director of the Manchester (N.H.) Water Works, chairman of AWWA's Water Utility Council, and member of the AWWA Research Foundation's board of trustees: James V. LaFrankie, president of the American Water Works Company Inc. and chairman of the board of the National Association of Water Companies since 1978: and Duane Georgeson, assistant general manager‐water for the Los Angeles Department of Water and Power. James F. Manwaring, executive director of the AWWA Research Foundation, was the moderator.

摘要:

The first generation of a computerized billing system was installed in Rochester, N.Y., in 1972, but 10 years later serious shortcomings were apparent. The author describes how the criteria for an updated system were developed and the process by which the water bureau chose an appropriate new system.

摘要:

A major portion of the cost of using granular activated carbon as a water treatment unit process is associated with the replacement or reactivation of spent carbon. Regional reactivation—the sharing of a reactivation furnace among several users—has been proposed as a means of minimizing this cost. To test this concept, a field‐scale regional reactivation project was conducted by the Manchester (N.H.) Water Works in conjunction with three other water utilities. Each of the three participating utilities provided 40 000 lb (18 160 kg) of carbon to be transported to Manchester for fluidized‐bed reactivation. Data were gathered on reactivation operations and costs, transportation costs, and carbon losses. Results of the study demonstrated that regional reactivation can be cost effective compared with carbon replacement and, in certain instances, compared with on‐site reactivation.

摘要:

What criteria for developing water rates are used by large industry? General Motors negotiates contracts with water utilities based on fairness to both the corporation and the water utility. Water revenues, in the view of GM, should be reasonable and adequate to maintain the financial and operational stability of the water utility. Charges should be based on selfsupporting, cost‐of‐service rates with little customer cross‐subsidization and minimal revenue subsidization from other sources, such as taxes. Written service contracts are suggested as an appropriate tool to achieve these goals.

摘要:

The use of reverse osmosis (RO) as a water treatment process in private industry has dramatically increased over the past five years because of increased product quality and membrane system performance. Design of RO systems must include a thorough examination of each unit process to determine the effect on preceding and succeeding units. Properly designed RO systems will provide effective industrial wastewater treatment, waste management, and recycling—all of which add up to higher quality product water at a reasonable cost.

摘要:

A coal‐fired electric power generating station near Brush, Colo., achieves zero discharge because the design included successful application of similar concepts at other stations, acknowledged areas where insufficient basic information was available, and was both conservative and flexible enough to allow modifications to be made with minimal disruption of normal operations.
