Abstract: A dispersion apparatus for dispersing a treating agent into a fluid treatment system that includes a flow duct in which a fluid stream flowing through the duct is mixed with the treating agent. The apparatus is based on a multi-pipe lance positioned in the stream flow, where each pipe supplies a minimum of feed discharge nozzles (typically one to four), and the individual pipes branch off from the same location.
