Use of constructed mixed microbial mats for landfill leachate treatment

BIOMAT{trademark} (Mats) is a system of constructed microbial mats which are natural heterotrophic and autotrophic communities dominated by cyanobacteria (blue-green algae). Mats constructed with specific microbial components have been developed for various bioremediation applications: removal of metals, organic degradation, removal of radionuclides, treatment of mixed contaminants, biological treatment ponds, and soil remediation. Based on the potential applications of the constructed microbial mat system, a pilot scale leachate treatment system has been constructed at the Waste Management, Inc. Outer Loop RDF near Louisville, KY in conjunction with M.A.T.S., Inc. The system consists of two lined lagoons with various constructed mat configurations. Changes in leachate chemistry including: pH, dissolved oxygen, color, nitrate/nitrite and ammonium concentration were monitored on influent and effluent leachate streams and within the pilot system to determine operational characteristics of the constructed microbial mat system. The M.A.T.S., Inc. treatment system is expected to reduce capital costs for leachate treatment plants, decrease leachate treatment operating costs, and create a {open_quotes}green{close_quotes} self-contained image for landfills.
