The InstoMix high-energy flash mixer from Walker Process Equipment, a Division of McNish Corp., disperses coagulant and other flocculent solutions into raw water and wastewater. The flash blending (within milliseconds) of coagulant results in optimum floc formation and maximizes chemical economy. The compact in-line units are constructed for flange mounting directly in the pipeline and are equipped with an internal-feed manifold designed to distribute solutions uniformly throughout the sectionalized mixer body. The inline design allows a low-energy input, low headloss and high G-Value result. The agitator can be custom-sized to produce a desired G-Value. Units are available for 8- to 72-inch pipelines. 630/892-7921; www.walker-process.com.
