A Bug in the System: Using Bacteria to Treat Industrial Wastewater

A metal extrusion company found itself having issues with its Biochemical Oxygen Demand (BOD) in its wastewater treatment operation due to surfactants disrupting the bacteria.

Specifically, the company was treating rinse water that contained surfactants with biologics and related chemistries and, over a period of time, found their treatment process was having a less-than-desired effect.

They approached Hubbard-Hall with a need for a better culture that is more surfactant-resistant than what they had been using.
