Abstract:
A method of introducing water treatment chemicals to a water stream advancing within water containing equipment having only a single opening for introduction of the chemicals, the method comprising the steps of:(a) mounting a first quill member extending sealingly through the opening on the wall of the water containing equipment so as to have a first inlet located outside of the water containing equipment, a first outlet located within the water containing equipment in the path of the advancing water stream, and a first passage extending between the first inlet and the first outlet;(b) mounting a second quill member on the first quill member so as to have a second inlet located outside of the water containing equipment, a second outlet located within the water containing equipment in the path of the advancing water stream, the second outlet being spaced from the first outlet, and a second passage extending between the second inlet and the second outlet, the second passage being coaxial with the first passage;(c) introducing a first chemical substance for flow through the first passage so as to issue from the first outlet into the water stream;(d) introducing a second chemical substance for flow through the second passage so as to issue from the second outlet into the water stream, whereby the first and second chemical substances avoid mixing in a concentrated form in the advancing water stream.
