Читать книгу Automation of Water Resource Recovery Facilities - Water Environment Federation - Страница 14

When Water Environment Federation’s (WEF’s) Automation of Water Resource Recovery Facilities Task Force first defined the scope of this update, they estimated that the manual would be approximately 600 pages (about 10% longer than the 2006 edition’s 576 pages) to accommodate new developments in the field.

After considerable discussion on what to keep, add, and leave out, the task force decided to update much of the material in the previous editions, except for obsolete technologies and technologies for which considerable written material was already available. The task force also incorporated much of the content of WEF’s now out-of-print 1997 Special Publication, Automated Process Control Strategies, which is the latest guidance document on specific process control strategies for wastewater treatment systems. The task force did not discuss the important issue of data quality. Fortunately, Olsson and Newell (1999) present an excellent discussion of the topic. The task force also decided not to debate the relative merits of traditional design–bid–build and design–build contracts or to address construction management issues. The task force did not address the issue of contract vs in-house programming. In addition, the task force did not address collection system controls in this edition because that topic was covered thoroughly in Design of Urban Stormwater Controls (WEF et al., 2012).
