This study program encompassed an evaluation of available research data from the various scientific disciplines on chlorine disinfection, application of this information in defining the disinfection process principles, and formulation of a rational engineering design approach for the chlorine disinfection process in domestic wastewater treatment. Experimentation to determine reactor flow characteristics was conducted using a laboratory-scale process unit similar to full-scale units presently being employed in wastewater treatment practice. Characteristics of the flow patterns for different internal baffling arrangements were evaluated with discussions presented on their effects to the efficiency of the process. Recommendations include a rational design procedure for the chlorine disinfection process, suggested design parameters for the process reactor, and an outline for further investigations.
