New EcoVerde bacteria-based filter removes odor from wastewater

U.S.-based company EcoVerde created a new filtering system that uses bacteria to get rid of odors and other undesirables in wastewater, according to a release from Investigación y Desarrollo.

The process funnels air from over the sewage water and sends to the “bioscrubber EG” system. The air is then removed and the odor-causing organisms are sent to the filter where waiting bacteria destroy them. The filtration system employs a combination of autotrophic and heterotrophic bacteria to remove a variety of pollutants using oxidation.

The system can handle highly polluted sewage as this means more food for the bacteria without raising costs. EcoVerde has extended its technology to Mexico to assist districts near sewage plants.
