Siemens Water Technologies acquires JetMix system from Liquid Dynamics Corp

The JetMix system allows operators to schedule mixing times, which can reduce power usage by 60 to 80% without decreasing gas production or negatively affecting volatile solids reduction. JetMix is suitable for use in new installations, retrofits or upgrades for a variety of municipal and industrial applications, and complements Siemens’ existing line of equipment and solutions for anaerobic digestion.

JetMix mixing solutions for anaerobic digesters and sludge storage tanks ensure efficient mixing through specialized nozzle design and configuration. The JetMix system creates an effective mixing volume rating of 95% or more, even with internal piping and roof support columns. The system uses powerful jets to maintain or re-suspend solids. Nozzles mounted inside the tank can be rotated 360º to create a flow pattern that virtually eliminates solids settling, reduces energy requirements, and makes dead spots obsolete. A top nozzle effectively controls scum and grease as well as foam and other floatables.

The modular design of the JetMix system allows for various pumps and nozzles to be used in combination to meet a wide range of application requirements and load fluctuations. Viscosity, particle size, density, settling rate and tank geometry are all considered when designing the mixing system. The mixing system can be paired with thermophilic as well as mesophilic digesters, and can be coupled with heat exchangers. The system can be used in channels as well as in circular, square, and rectangular tanks. Suitable applications include tanks with gas holders, or fixed and membrane roofs, with the tanks located either above or below ground.
