SALT LAKE CITY, January 10, 2011 Inexpensive igloo-shaped, pollution-eating devices nicknamed "Poo-Gloos" can clean up sewage just as effectively as multimillion-dollar treatment facilities for towns outgrowing their waste-treatment lagoons, according to a new study.
"The results of this study show that it is possible to save communities with existing lagoon systems hundreds of thousands, if not millions of dollars, by retrofitting their existing wastewater treatment facilities with Poo-Gloos," says Fred Jaeger, chief executive officer of Wastewater Compliance Systems, Inc., which sells the Poo-Gloo under the name Bio-Dome.
Kraig Johnson, chief technology officer for Wastewater Compliance Systems, will present the study Jan. 13 in Miami during the Water Environment Federation's Impaired Water Symposium. It also will be published in the symposium program.
Wastewater treatment in small, rural communities is an important and challenging engineering task. Proper treatment includes disinfection and the removal of unwanted pollutants. Most rural communities rely on wastewater lagoons as their primary method of treatment because they are simple and inexpensive to operate. Lagoons are large ponds in which sewage is held for a month to a year so that solids settle and sunlight, bacteria, wind and other natural processes clean the water, sometimes with the help of aeration.
But as communities grow and-or pollution discharge requirements become more stringent, typical wastewater lagoons no longer can provide adequate treatment. Until now, the only alternative for these communities was to replace lagoons with mechanical treatment plants, which are expensive to build and operate. Mechanical plants treat water in 30 days or less, using moving parts to mix and aerate the sewage, speeding the cleanup. They require electricity, manpower and sometimes chemicals.
