Igloo-shaped 'Poo-Gloos' eat sewage
Date:1/8/2011

important, by as much as 93 percent when temperatures dropped below 50 degrees Fahrenheit conditions that normally slow bacterial breakdown of sewage.

  • Total nitrogen levels fell 68 percent in warmer water and 55 percent in cooler water.

    "The removal rates we saw during the pilot test are comparable to removal rates from a rotating biological contactor, which is a commonly used device in mechanical treatment facilities," Johnson says. "We couldn't be happier with the performance of the Poo-Gloos."

    Johnson conducted the study with Hua Xu, a postdoctoral fellow in civil and environmental engineering at the University of Utah, and Youngik Choi, a professor of environmental engineering at Dong-A University in South Korea.

    There may be uses for the Poo-Gloos beyond municipal wastewater treatment.

    "The bugs will adapt to consume whatever is available," says Johnson, "In addition to the pollutants discussed in our paper, we've also seen great results in the consumption of other significant pollutants that I can't discuss now because we're in the process of filing patents. Poo-Gloos or Bio-Domes as we call them have a lot of potential, and we've only just scratched the surface."

    Johnson and his team originally nicknamed the devices Poo-Gloos because they are shaped like igloos. But as possible uses began to expand to industries beyond municipal sewage treatment, Wastewater Compliance Systems decided to sell them as Bio-Domes.

    From Nevada to Alabama and Wisconsin, Poo-Gloos to the Rescue

    "Every day I speak with community officials who need to upgrade their treatment facilities," says Taylor Reynolds, director of sales for Wastewater Compliance Systems. "They come to us because they receive an engineering report recommending a $4 million to $10 million mechanical plant project that is impossible for them to pay for with their existing tax base. Not only can our Poo-Gloos or Bio-Domes
