Abstract:
1. An arrangement for the addition of chlorine dioxide to a water-carrying pipeline, comprising: a section of the pipeline having a longitudinal axis; a dead water zone extending radially from the pipeline section; and a cylindrical shaft passing through the dead water zone directed radially to the longitudinal axis of the pipe-line and extending at least to the longitudinal axis of the pipeline; wherein the cylindrical shaft comprises: a reaction chamber at a distal end oriented such that the reaction chamber is within the pipeline; and a solid proximal portion being a solid shaft defining two separate reactant supply lines to the reaction chamber; the two separate reactant lines run longitudinally through the solid shaft from outside the water pipeline into the reaction chamber, and wherein the reaction chamber comprises an exit hole having an axis, which in a service state is oriented in the direction of the longitudinal axis of the pipeline and in a flow direction of the water, and chlorine dioxide obtained by reaction of reactants in the reaction chamber passes through the exit hole into water in the pipeline.
