Effective mixing is important to optimizing biogas production in anaerobic digesters. There are various approaches to mixing systems, including mechanical stirring with paddles, pumping jets of material, and pumping biogas through the slurry.Landia, based in Denmark with U.S. operations in North Carolina, offers a mixing technology to the North American market that combines two of those basic methods — jets of material, and aspirating and injecting biogas. The GasMix technology places all rotating components outside the digester tank, helping to reduce wear and tear and simplifying maintenance.The technology is suitable for mixing solids from wastewater treatment as well as food
