Water Treatment Plant audit procedures for algal blooms

March 27, 2018

A new WaterRA document will enable water treatment plant operators to assess and quantify the effectiveness of each step in their plant's treatment train during a cyanobacteria challenge.

This document is the final resource of project 1078 "Development of tools for the assessment and management of aesthetic and health risks associated with cyanobacteria". 

The aim of the project was to provide Australian water utilities with a suite of user-friendly and straightforward resources to support the Australian Drinking Water Guidelines, specifically for the assessment and management of the aesthetic and toxicity risks associated with cyanobacteria.

The questions addressed are:

  • How can we have confidence in the application of various treatment processes when they are often site/system specific?
  • What is the evidence the removals of cyanobacteria and metabolites reported in the literature and guidance manuals are achievable at the full scale?
  • How can we assess and validate the efficiencies of unit processes at individual treatment plants?
  • What is the combined mitigation effect of the entire treatment train?
  • In the case of a toxic bloom, how can we determine the point at which we are at risk of distributing water that does not meet the Australian Drinking Water Guidelines (ADWG) for toxin concentrations?

"Treatment Plant Audit for Cyanobacterial Metabolites and Taste and Odours" provides step-by-step procedures for both audit and investigative sampling that can be tailored for individual treatment plants.

All of the documents pertaining to this project are now available to Members via the project page. You must be logged in to see and access these docuemtns.
