Claim:
A waste liquid treatment system comprising the following: A. a media matrix ( 1 ) comprised of at least one inner core ( 70 ) received into at least one tube ( 20 ); B. the media matrix ( 1 ) received into a media matrix container ( 250 ) having wastewater inlet ( 350 ) and discharge means ( 400 ), C. the media matrix ( 1 ) is comprised of a plurality of tubes ( 20 ) each sized to receive at least one elongated inner core ( 70 ); D. the at least one inner core ( 70 ) has a top ( 75 ), a bottom ( 80 ) and a length ( 85 ); E. the tube ( 20 ) having a tube top ( 25 ), tube bottom ( 30 ) and tube length ( 35 ) and a tube axis ( 37 ); the tube axis ( 37 ) centrally positioned from the tube top ( 25 ) to the tube bottom ( 30 ) and extending throughout the tube length ( 35 ) of each tube ( 20 ); F. the inner core ( 70 ) having at least one vane ( 90 ); G. the at least one vane ( 90 ) extending from a central core element ( 95 ) where the central core element ( 95 ) coincides with the tube axis ( 25 ). H. the inner core ( 70 ) having a plurality of vanes ( 90 ); the central core element ( 95 ) of at least one inner core ( 70 ) parallel with the central core element ( 95 ) of other at least one inner core ( 70 ); I. the tube length ( 35 ) generally less than the inner core length ( 85 ), J. The tube ( 20 ) having an inner wall ( 140 ) where at least one groove ( 150 ) is formed in the inner wall ( 140 ); said at least one groove ( 150 ) sized to receive at least one vane ( 90 ); K. the at least one groove ( 150 ) receives and restrains at least one vane ( 90 ) of the at least one inner core ( 70 ) in a position within said tube ( 20 ); L. the tube ( 20 ) having an outer wall ( 190 ) having at least one fin ( 200 ) extending outwardly therefrom.
