Abstract
A method and apparatus for a Coanda effect-induced tube settler assembly lamellae cleaning system for raw water or semi-potable drinking water treatment clarifier. A tangential compressed air source is injected from compressed air tubes near J-shaped support deflector beams. The combined high pressure air from a high pressure fixed air grid and waste water fluid flow stream in a main waste water stream to be clarified, creates a Coanda-effect fluid inducing turbulence when used in conjunction with cross-sectionally J-shaped deflector beams. This combined fluid flowstream provides hydrodynamic cleaning pressure axially through the tubes' lumen of the tube settler assembly within a clarifier cell basin enclosure.
