Mixing system
Vaughan's Rotamix® process mixing system incorporates the combination of heavy-duty ductile iron nozzle assemblies with the company's chopper pump. The mixing system creates dual-zone mixing and a vertical-axis vortex, assuring uniform mixing velocities and eliminating dead spots. The dual zone mixing consists of two rotational patterns: uniform rotation which causes the entire contents to rotate, and vortical rotation which creates high velocity at the tank center. The chopper pump conditions solids while eliminating nozzle plugging.

Acidic wastewater treatment
Dow's MHT® Magnesium Hydroxide is a stable, alkaline slurry used to neutralize acidic wastewater streams. End users typically find that the product improves pH control and reduces sludge generation. Control of pH is improved because the product reacts quickly at lower pH and slowly at higher pH, naturally helping to hit the desired pH target without excessive over-shoot. With other alkalis, over-addition can cause pH to hit 11 or 12; however, MHT tends to buffer around a maximum pH of 9.
