In {HEAD ~ contrast} to Orts method, I have surprisingly discovered that in an ATS floway, the floway operating conditions may be adjusted such that rapid precipitation of pollutants occurs only onto and into the cells or cell walls of the algae, rather than into the water, and the pH of the water is not allowed to increase, and that this can be achieved without {TAIL ~ addition} of substantial amounts of costly chemicals or additional process steps
