An apparatus and method for increasing the mass transfer of a treatment substance into a liquid flowing in a pipe in a full pipe flow regime has a diversion conduit which receives a portion of the liquid. The portion of the liquid is mixed with a treatment substance and then reintroduced into the pipe at a downstream location through an injection structure. Between the diversion conduit, on the upstream side, and the injection structure, on the downstream side, there are a plurality of flow vanes disposed circumferentially about a cylindrical inner wall of the pipe, where each flow vane extends radially inward toward a central axis of the pipe, extending into the main stream flow of the liquid. Another embodiment of the invention has a flow grid located downstream of the injection structure.

The apparatus of claim 3 wherein the plurality of nozzles comprises a plurality of pairs of nozzles, wherein each pair comprises a first nozzle and a second nozzle, wherein each pair of nozzles is spaced apart linearly along a length of the pipe from an adjacent pair of nozzles. 6. The apparatus of claim 5 wherein the first nozzle and the second nozzle are disposed in the pipe in opposite facing relation. 7. The apparatus of claim 1 wherein a booster pump is hydraulically connected to the diversion conduit, wherein the booster pump is configured to receive the diversion flow and boost the pressure of the diversion flow. 8. The apparatus of claim 7 wherein the treatment substance mixing apparatus comprises an aspirating injector which receives said diversion flow from the booster pump and mixes the treatment substance with the diversion flow. 9. The apparatus of claim 1 wherein the diversion flow is in a range of 3 percent to 40 percent of the flow of the liquid. 10. The apparatus of claim 1 further comprising a flow grid disposed in a second downstream location, the flow grid disposed perpendicular to the central axis, the flow grid having an upstream face and a downstream face. 11. The apparatus of claim 10 wherein the flow grid comprises a plurality of intersecting grid members. 12. The apparatus of claim 11 wherein the flow grid comprises a semi-circular shape having a diagonal base member. 13. The apparatus of claim 12 wherein a cross-sectional area of the pipe into which the flow grid is disposed defines a circle of 360 degrees with a zero degree position defined at a top of the pipe, wherein the diagonal base member has a first end adjacent to an approximate 60 degree position of the circle and the diagonal base member has a second end adjacent to an approximate 240 degrees position of the circle. 14. The apparatus of claim 12 wherein the flow grid comprises a first half of the semi-circular shape and a second half of the semi-circular shape, the first half and the second half each comprising a plurality of intersecting grid members disposed in a parallel configuration with the diagonal base member. 15. The apparatus of claim 14 wherein each intersecting grid member of the first half, from the upstream face to the downstream face, is disposed in an approximate angle of 10 degrees upward from the central axis. 16. The apparatus of claim 14 wherein each intersecting member of the second half, from the upstream face to the downstream face, is disposed in an approximate angle of 10 degrees downward from the central axis. 17. The apparatus of claim 10 wherein the flow grid comprises a plurality of square openings. 18. The apparatus of claim 17 wherein each of the square openings is approximately two inches by two inches. 19. The apparatus of claim 10 wherein the flow grid comprises a plurality of rectangular openings. 20.
