  • the invention may also be applied to the treatment of other liquids.
  • Fresh water for potable, agricultural, industrial and other purposes is in short supply in many parts of the world. In such locations, local rainfall precipitation is not sufficient to satisfy fresh water demand. For example, in Australia, a large percentage of the rain fall occurs in coastal regions, and the arid central region has very little rain fall or other naturally occurring sources of fresh water. As such, the inability to obtain sufficient quantities of suitable fresh surface water sources directly affects the suitability of land for residential or agricultural use.

  • Settlement treatment provides a means of treating water for some contaminants such as iron and/or other metallic contaminants. However, settlement alone is not sufficient to address all possible sources of contamination. A further drawback with settlement systems concerns the amount of time required to settle the water before usage.
