Big bubble mixing technology

“Big bubble” mixing technology provides a cost-effective method of pH equalization using magnesium hydroxide rather than sodium hydroxide. Unlike NaOH, which is toxic, Mg(OH)2 is nontoxic, and it is four times more effective than NaOH at lowering the pH of water. Sodium hydroxide is typically used for neutralization because Mg(OH)2 tends to settle, making it difficult to mix using conventional equipment. This new technology effectively mixes Mg(OH)2 in tanks of almost any size, configuration or material of construction. To be used for Mg(OH)2, conventional mixers require additional structural supports, baffles, special openings, and new power sources. Big bubble technology can be installed in new and existing tanks without these costly enhancements; it requires only the installation of an accumulator plate (or multiple plates) that sweeps the tank floor. Compressed air injected under the plate forms a large bubble that pulls particles and heavy liquids behind it as it rises to the surface, creating vertical circulation and mixing. The mixer’s control system can be either electronic or pneumatic.
