90-10: Problems and Pitfalls in Water Treatment Specifications

This paper discusses the process of preparing specifications for chemical treatment of major cooling water systems, evaluating bid responses and operating systems in accordance with specifications. Subjects covered include: proper use of historical operating and performance data; selection of critical parameters and performance standards; the need for flexibility to permit evaluation of alternative proposals; the importance of defined responsibilities for both vendor, and user; evaluation of proposals and selection of vendor, and short and long term accountability for performance in vendor/user partnership after bid has been awarded. Although the paper deals primarily with large electric utility plants, the principles apply well to industrial plants and to other water treatment systems.
