In wastewater and drinking water treatment, we have to mix things into the water for treatment (flocculants, coagulants and disinfectants) or just try to keep things in contact with each other (biochemical oxygen demand, oxygen and microorganisms). One of the major costs associated with this mixing is electricity. I came across this article that outlines a different technology to help alleviate some of that cost and wanted to share with you.
The slow speed nonaerating submersible mixers may be used in wastewater treatment for denitrification and/or phosphorus reduction where anoxic or anaerobic conditions dictate that mixing and required velocities be accomplished without aeration. Once again, this is just our way of sharing information to with our readers. To check out this article, click here.
