The Office of the Vice President for Research is pleased to host the next Water@Wayne seminar on Thursday, October 5, 2017 at 2:30 p.m to 3:30 p.m. in the Purdy/Kresge Library, room 0110. The seminar is free and open to the public.

The Water@Wayne Seminar Series presents "Permanganate Pre-Oxidation: Evaluating Its Viability as a Strategy for Utilities to Meet Drinking Water Standards for Algal Toxins," with Dr. Allison MacKay, Ohio State University. Dr. MacKay is professor and chair of the Department of Civil, Environmental and Geodetic Engineering at The Ohio State University. Dr. MacKay’s research focuses on the physico-chemical processes that govern how environmental contaminants are transported and react in natural aquatic systems and engineered water treatment systems.


Naturally-occurring algal toxins can pose a hazard to drinking water consumers if they are present at only low levels in the water supply. Most water treatment plants were not designed with the goal to reduce algal toxin concentrations; yet, some conventional treatment processes – such as permanganate oxidation – do have the potential to reduce levels of algal toxins in water. As part of the Ohio Harmful Algal Bloom Research Initiative, we are examining the reactivity of potassium permanganate with commonly-occurring algal toxins. Permanganate is a robust oxidant to react with the toxin microcystin, showing no variation of reaction rates with pH or alkalinity. Naturally-occurring organic materials in water do consume permanganate and slow its reactivity with microcystin. Permanganate pre-oxidation alone can be an effective treatment strategy to reduce microcystin concentrations to acceptable levels for drinking water sources with low exceedance factors; augmentation of permanganate pre-oxidation with additional treatments will be necessary for water sources subject to perennial algal bloom conditions.

A short reception will immediately follow the seminar.
