December 17, 2001 — Economic and Engineering Services, Inc., American Water Works Service Company, Inc., and Carollo Engineers were selected to conduct a study entitled "Optimizing Chloramine Treatment" (AwwaRF RFP 2760).
The goal of this project is to develop "Practical Chloramination Guidelines for use in the Utility Operation Toolbox", and one of the deliverables of this project will be an updated version of the popular "Optimizing Chloramine Treatment" AwwaRF Manual, published in 1993.
To meet project goals and objectives, a five-step approach was developed:
• Task 1 - Assemble the Latest Information
• Task 2 - Develop and Conduct Chloramine Survey
• Task 3 - Identify and Conduct Case Studies
• Task 4 - Prepare New Chloramines Guidelines
• Task 5 - Empower the User
The objective of Task 2 is to conduct a survey of all relevant operational and practical information, as well as problems encountered and control practices, related to the use of chloramines in water treatment and distribution systems.
The study group is interested in practical experiences and engineering/operational solutions that can be applied to solve chloraminated systems problems.
The survey focuses on four key areas: (1) Decision Approach to chloramination, (2) Engineering Design Guidelines, (3) Start-up and Operation of Chloramine Treatment Facilities, and (4) Community Relations. The survey results will fill in the gaps where information about chloramination is missing, and help further define the case studies.
The group needs the participation of drinking water utilities that currently use chloramines in post-disinfection (secondary disinfectant), or are considering switching from free chlorination to chloramination, to answer the survey. Survey answers should be returned by Feb. 1, 2002. Following survey analysis, researchers may contact survey participants via telephone, fax or e-mail to clarify any answers or address any specific issues that may improve survey outcomes and enhance this project.
In addition, the last section of the questionnaire allows participants to elaborate on any issues addressed during this survey if they feel the survey format does not allow them to elaborate on a specific subject.
If the participant's water utility possesses more than one treatment plant, the largest plant that uses chloramine in post-disinfection should be the one considered to answer the survey questions.
Economic and Engineering Services, Inc., American Water Works Service Company, Inc. and Carollo Engineers are deeply grateful for your participation! The completion of this research project would not be possible without the support of people like you!
