Effect of Chlorine vs. Chloramine Treatment Techniques on Materials Degradation in Reclamation Infrastructure
Project ID: 6871
Principal Investigator: Jessica Torrey
Research Topic: Condition Assessment
Priority Area Assignments: 2013 (Advanced Water Treatment)
Funded Fiscal Years: 2013
Keywords: chlorine, chloramine, treated water, infrastructure materials
This scoping study will examine current state of knowledge in the field, the effects on Reclamation structures, and propose any research required to answer the following questions:
- What is the impact of chlorine and/or chloramine treatment on the lifetime and reliability of infrastructure such as pipeline materials, tanks, concrete and protective polymeric coatings?
- Is there a preferred treatment method, free chlorine vs. chloramines, for a given material? Conversely, given a specified treatment method, which materials should be considered for infrastructure design?
- What are the recommended water chemistries to prevent or inhibit materials degradation?
Need and Benefit
The findings of this scoping study will help guide materials selection when designing infrastructure for treated water either directly, through the identification of prior work, or indirectly by leading to recommendations for future research in this field.
