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

A metal extrusion company faced challenges with its wastewater treatment operation due to surfactants disrupting bacteria, leading to issues with Biochemical Oxygen Demand (BOD) levels. Seeking a solution, they approached Hubbard-Hall for a better culture that could resist surfactants. Hubbard-Hall’s technicians investigated the system, running 16 hours daily with a flow rate of 3,900 gallons per hour (GPH). They proposed using Aquapure Bio 20, a broad spectrum of microbial cultures designed to degrade hydrocarbon industrial wastes.

  • Aquapure Bio 20: Psychrophilic microbial cultures for hydrocarbon waste degradation, enhancing removal of TOC, COD, BOD, and TSS.
  • Aquapure Bio 230: Balanced blend of inorganic salts for optimal biomass growth conditions.

Excerpt: 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.
