Laboratory scale studies were conducted under controlled conditions and looked at:

  • Different coagulants, cell concentrations and source waters
  • Determining the optimum conditions and coagulant type and pH for each cyanobacteria type in different source waters
  • Whether it is possible to quantify the removal of cells during the optimised process, as well as the removal of intracellular and extracellular toxin, and any potential toxin release into the dissolved state that may occur during treatment
  • The results from this suite of experiments will add substantially to the existing knowledge regarding the optimisation of conventional treatment for the  removal of cyanobacteria and allow the project team to formulate guidelines regarding the most appropriate conditions required to meet the expected  drinking water quality criteria in both North America and Australia.
