A radial mixing header for use with apparatus that removes solids from a liquid by dissolved air flotation (DAF). The header comprises a par of concentric pipes circumscribed by a concentric mixing chamber having a tangential port for introduction of the recycled gas-liquid stream thereinto. The recycled stream achieves rotary and turbulent motion and mixes in a larger diameter pipe with the raw solids-containing stream which flows through a smaller diameter pipe.
