Patent ID: 7906018

Claim:
A water or wastewater treatment system for treating water or wastewater by mixing a reagent with the water or wastewater, the water or wastewater treatment system comprising: a. a reactor having a bottom, an inlet, and an outlet; b. a flow channel adapted to be immersed within the water or wastewater in the reactor, and generally vertically disposed in the reactor, the flow channel having an open upper end and an open lower end and a surrounding wall structure that permits water or wastewater to enter the open upper end and to flow downwardly through the flow channel and be discharged out the open lower end thereof; c. the lower end of the flow channel being spaced from the bottom of the reactor; d. an agitator disposed in the flow channel generally between the open upper and lower ends for mixing the reagent with the water or wastewater and for inducing water or wastewater from the reactor into the open upper end, and moving the water or wastewater downwardly through the flow channel to where the water or wastewater is discharged therefrom; e. a structure disposed in the vicinity of the lower end of the flow channel for engaging the water or wastewater and causing the flow of the water or wastewater leaving the flow channel and moving upwardly in the reactor to be less turbulent than the water or wastewater in the vicinity of the agitator in the flow channel; f. wherein the structure disposed in the vicinity of the lower end of the flow channel is a flow divider that divides the flow of water or wastewater being discharged from the flow channel; and g. wherein the flow divider includes a cruciform baffle having a series of intersecting vertical walls that assume a generally cylindrical configuration.
