Clean, Clear Water (1982)
Techniques for water purification have changed little over the past fifty years. But a new process called SIROFLOC, developed by CSIRO”s Division of Chemical Technology, offers a major advance in the efficiency and effectiveness of this technology.
SIROFLOC uses a natural iron oxide called magnetite to extract impurities. It is faster, cheaper and more thorough than conventional processes, and the magnetite can be re-cycled, eliminating major sludge disposal problems.
This film explains the process in the context of Australia’s limited water resources and looks at the first commercial plant which is operating in Perth.
