National Research Priority: Supply Optimisation

Project Description

This project improved the knowledge of how algae species (population density, morphology and AOM concentration and character) and coagulation conditions (coagulant type, pH, polymer dose, and shear) impact algal floc properties in order to improve the C-F process and downstream separation treatment.

PhD Thesis completed by Andrea Del Pilar Gonzalez Torres in June 2018.

Project Description

There are many species of blue-green algae (cyanobacteria), and each species can have a number of genotypes. Water utilities routinely monitor reservoirs and lagoons for the harmful toxin-producing species, and when they find a threshold number of cells, proceed to test for toxins. The problem is that not all genotypes of known toxin-producing species produce toxins. There is already a well-established quantitative PCR method that detects the genes responsible for making toxins, but the relationship between occurrence of these toxic genotypes and the amount of toxin in one water sample is not straightforward.

This project will create a modified version of the existing regulatory protocols for managing toxic blue-green algal blooms by adding the toxic gene qPCR test to the current tests for toxin and species identification. This modified protocol will then be used to assess samples for which there are already results from all three tests. The original management costs will be compared to the desktop analysis of hypothetical costs that would have been incurred if genotoxicity testing had been included in the protocol. Could gene testing reduce overall cyanobacteria management costs and confer operational benefits?

Project Description

There is a need to have a clear and consistent approach to assessing the efficacy and performance of the growing number of algal bloom management technologies emerging on the market. Often technologies are offered by suppliers with the promise that they will solve algal bloom issues. However, there are a number of factors that, if poorly understood and addressed, can result in performance being unsatisfactory for water utility needs. This research will develop a customisable protocol for selection, deployment, and performance assessment of algal bloom management technologies.
