A hydraulic jet flash mixer in a system for treating waste water jets a secondary flow of water through a high-velocity nozzle towards a deflector assembly. In one embodiment, the deflector assembly is formed by a tip and a body, and the tip is spaced from, but spring biased toward, the body. The space between the tip and body acts as a nozzle for radially injecting a coagulant fed to the body by a pressurized supply line. In another embodiment, the deflector assembly is one piece, and the supply line is inside of and extends through the high-velocity nozzle such that coagulant is injected from a point between the nozzle and the deflector assembly.

A flocculation system for water treatment facilities comprises a flocculation tank having a plurality of baffles which divide the interior of the flocculation tank into a plurality of compartments. The baffles are arranged to provide intercompartmental openings between adjacent upstream and downstream compartments, which, in turn, are arranged to provide a serpentine flow path through the flocculation tank. A mechanical mixer is mounted in each compartment for supplementing the mixing energy provided by the serpentine flow, particularly during periods of low water flow rates.
