A method and apparatus for treating wastewater. The apparatus comprises a reactor having a flow channel generally centrally located in a reactor and immersed in the water or wastewater in the reactor. An agitator is disposed within the flow channel and induces water or wastewater to enter the open upper end thereof and to move downwardly through the flow channel where the water or wastewater is discharged via a flow divider. A reagent is injected into the water or wastewater and the agitator within the flow channel serves to mix the reagent with the water or wastewater passing therethrough and in the process causes at least a slightly turbulent and downward axial flow through the flow channel.

System for treating wastewater

A gravitational separation device for purifying water includes a basin for receiving and holding the water. The basin includes an internal wall. At least one supply channel is provided to the periphery of the basin for providing water to the basin. A plurality of openings is provided in a bottom or floor portion of the supply channel. Disposed under the openings is a plurality of deflector plates. A skirt spaced from the internal wall of the basin is inclined towards the interior of the basin at an angle of approximately 5&#xb0; to 80&#xb0;. A discharge channel is provided for discharging liquid from the basin, and there is also provided a device for discharging suspended particles.
