Algae Removal

Algae, or more accurately plankton create several problems including:
  • algal blooms
  • poor coagulation and flocculation
  • poor settling characteristics
  • various odors and tastes
  • some species may by toxic
  • whether living or dead can be responsible for bacterial growth

  • Ozone is effective at killing microorganisms, including algae, because of its strong oxidizing capabilities targeting the cell membrane. Ozone is also capable of inactivating certain zooplankton, including certain mobile organisms like Notholca caudata. In order to remove such organisms by either flocculation or filtration, they must first be inactivated. The table below illustrates the advantage of inactivation as a preliminary step in the removal of certain types of plankton.
