Managing Intracellular Cyanotoxin Release During Oxidation Processes in Drinking Water Treatment Plants
Utilities have been seeking guidance to effectively control cyanobacteria cells and eliminate cyanotoxins using holistic management and treatment strategies. Current guidance suggests that switching water sources or removing intact cells can minimize the risk of releasing intracellular (or cell-bound) cyanotoxins. Our presenters discussed options to use when this operational flexibility is unavailable, including the deliberate release and treatment of intracellular cyanotoxins using oxidation processes. In addition, the incorporation of intracellular cyanotoxin release into the upcoming CyanoTOX Tool (Version 3) was presented. The webcast included information from the WRF Tailored Collaboration project 4692, Release of Intracellular Cyanotoxins During Oxidation of Naturally Occurring and Lab Cultured Cyanobacteria, which highlights ways to improve available guidance to utilities regarding the release of intracellular cyanotoxins during oxidation of naturally occurring and lab-cultured cyanobacteria.
