Drinking Water Research Studies for Boston 's Pilot Treatment Program

CH2M Hill Consulting Engineers, 9/1/90-12/31/91

PIs: Reckhow & Edzwald
Students: Stephen Finch, Qingwen Zhu

The general purpose of this study was to collect water quality data, and conduct bench-scale and pilot-scale testing to help MWRA determine the best way to comply with the SDWA. The UMass portion of this work first focused on bench-scale testing of ozonation and its impacts on DBPs, AOC, T&O compounds and coagulation process performance. Later UMass provided analytical support for DBP precursor removal in the pilot studies.

Proposal, Plans and Reports

• Pilot Treatment Program Plans: Workplan (7/90); Preliminary Design (11/90)
• Review of Existing Data (10/90)

• Early Bench Testing plan, Bench-Scale Testing (1/91)
• Impact of Ozone and Peroxone on DBPs and AOC (Reckhow, 10/91)
• Ozone as an Aid to Coagulation (Edzwald & Paralkar, 12/91)
• Impact of Ozone on T&O Compounds (Reckhow & Zhu, 2/92)
• Pilot Testing Reports: One season (1/92); Two season (4/92); appendix (4/92); Three Season (6/92); appendix (6/92)
• Draft Final Report Appendices (10/92): Volume I - WQ & Bench-scale; Volume II - Pilot-scale

Project Data
