An Examination of the Benefits and Disadvantages with Respect to the Disposal of Solid Wastes

摘要

The ASCE Project concept envisions the installation of new systems of pressure sanitary sewers as a method of diverting sanitary sewage from existing combined sewers. The possibility of obtaining synergistic benefits by adapting the Project scheme to the disposal of solid wastes was recognized early in the Project program. The purpose of this memorandum is to examine considerations that are important to an evaluation of the feasibility and benefits of adapting the Project scheme to solid wastes disposal. Most of these considerations apply to any system of sanitary sewers. Considerations common to both open channel and pressure sanitary sewers are discussed first, followed by an examination of considerations peculiar to adaptation of the Project scheme to the disposal of solid wastes. Much of the discussion herein is speculative - a review of possibilities that depend on the results of needed research regarding the behavior of solid wastes in sewers and treatment plants and on the development of suitable devices and processes for handling solid wastes in sewage disposal systems.
