Increasing the effectiveness and simplicity of potable water reuse with a multi-benefit ferrate treatment process

Project ID: 22078
Principal Investigator: Catherine Hoffman
Research Topic: Desalination and Water Treatment
Funded Fiscal Years: 2022, 2023 and 2024
Keywords: None

Research Question

This project aims to answer the following research questions via targeted experiments and cost analyses.

1. Can ferrate and/or activated ferrate (AF) provide adequate pre-oxidation for biologically active filtration (BAF) for potable reuse (PR)?
-- Determine ferrate and AF doses to accomplish equal or better pre-oxidation as compared to ozone.

2. Does ferrate and/or AF perform better in the presence of lime softening?
-- Quantify performance benefits of combined lime softening/ferrate treatment to multiple processes (pre-oxidation, coagulation, pathogen removal, and disinfection byproduct [DBP] formation).

3. Is ferrate and/or AF more cost effective (capital and operations and maintenance [O&M]) than coagulant and ozone addition?

Need and Benefit

This research will develop an innovative, multi-benefit ferrate water treatment process for treatment of impaired water (wastewater) for potable use. Since this treatment process aids in the production of high-quality water, the end uses can be more diverse than for lower quality types of reclaimed water. In addition to drinking water, potential applications include agricultural, industrial, and other municipal uses. This work is supported by Yuliana Porras-Mendoza (S&T Research Coordinator).
