Abstract

The reactor, separated by a perforated partition from an overhead "plug flow" reaction chamber, has a bottom inlet below a pref. convergent/divergent blending nozzle, to the throat of which is fed a reagent, e.g. a coagulant, flocculant etc. The reactor has low pressure drop(. 2-. 5 bar), low power requirment, reduced dead space, and is not subject to by-passing reaction may be controlled in response to sensors (e.g. pH detectors) in upper and lower chambers. The reactor is esp. for treatment of waste water, e.g. with lime or H2SO4 to control pH.
