Packed columns containing polyvinylpyridine-bromine complex in the bead form were eluted by a continuous stream of water. The permeability of the columns was sufficient to allow maximum rates of elution at relatively low head loss. The rate of bromine elution was studied as a function of time and column length, prior to application of these columns in water disinfection. After an initial period of about 0.5 h the rate of bromine elution followed an inverse function of time. At any state of column depletion the rate of bromine supply was proportional to the flowrate at low flows and independent of flowrate at high flows, pointing to different rate determining mechanisms for each flow range.
