摘要:

When planning new water systems it is necessary to consider public wants as much as their needs. Financial planning, therefore, plays at least as important a role as the physical planning of the facility. The public must be educated to accept the costs of better service, and the utility must then implement the program so as to retain the public's confidence. All of these features must be incorporated into a 20‐yr master plan.

摘要:

Part I, last month, detailed the use of magnesium carbonate for the coagulation of organic color and turbidity in both natural and synthetic waters and dealt primarily with the laboratory evaluations and the results of these studies. This article discusses the economic evaluation of this new process, some of the theoretical relationships derived, and its application to in‐plant use.
