A hydrodynamical dispersive flash mixing system with six pressured water jets and one nozzle for the injection of aluminum sulfate solution. The flash mixer, conceptually original, is highly recommended for medium, large, and extra large diameters of influent pipeline. The flash mixer introduced is very effective, flexible, reliable and cost savings. The flash mixer obtains an optimal coagulation, avoids clogging of pipes and nozzles with aluminum hydroxide scale, avoids the effects of water temperature, and controls the changes of flow capacity and coagulant dose. The hydrodynamical dispersive flash mixer with pressured water jets can be installed inside or outside the influent pipeline. One option is described for the installation of flash mixer inside the pipeline and three options for installing it outside the influent pipeline. Also, four alternatives are presented for the connection of the flash mixing system with the liquid chemical feed system.
