ROTAMIX TANK MIXING

The Rotamix system uses fixed nozzle assemblies. Once the nozzle assembly is installed, the nozzles are adjusted to the design- specific angle, and permanently tightened. No additional adjustment is required.

Nozzle assemblies are offered in single and double nozzle configurations, depending on tank diameter and depth. All fittings are ductile cast iron and glass-lined for abrasion resistance, reduced friction, and to eliminate Struvite adhesion. The tapered nozzle barrels are 1-inch thick for long-term wear protection. The entire assembly is white metal sandblasted, and then powder coated with a Bonded Epoxy Coating, a one-part, heat-curable, thermosetting epoxy coating for superior surface protection. Each nozzle assembly includes a full 10-year warranty.

Nobody else in the market can offer a system to match the performance of the Rotamix Systems Nozzle Assemblies and the Vaughan Chopper Pump.

Vaughan’s chopper pump is the heart of the Rotamix system. Vaughan’s proven technology over the past 50+ years provides low maintenance, long-term, and the highest reliability of any chopper pump. Continuously chopped solids not only eliminate nozzle clogging, but enhance sludge quality. When used in a digester, efficiency of the AD process is increased by further reducing solids size and increasing surface contact.

COMPUTATIONAL FLUID DYNAMICS

The CFD (Computational Fluid Dynamics) software used at Vaughan Co., Inc. for analysis is among the top programs available in the world for this type of detailed computer flow modeling work. The problem is solved using techniques similar to finite element stress analysis. Essentially, the fluid volume is broken down into hundreds of thousands of volume elements to be analysed. Final results can be plotted in various formats including vector, velocity and streamline, on various tank configurations including cylindrical, rectangular and oval.

All Rotamix designs are supported by CFD analysis, either by standard modelled geometries, or using customized models individualized to meet specific application parameters on a consultation basis.
