Problem: The City and Bureau of Juneau, Alaska, produces 7,000 wet tons of dewatered biosolids each year. The material is hauled 1,300 miles by truck, barge and train to the Columbia Ridge landfill in Arlington, Oregon. This transport poses multiple risks and costs, and the utility faced uncertainty over environmental regulations.
Solution: Officials chose the Veolia BioCon medium-temperature belt dryer. The Class A EQ product provides pathogen reduction and diversifies end uses, which can include landfill cover material, fertilizer for community sites and parks, erosion control and topsoil replacement. These uses offer potential for significantly lower cost versus long-distance shipping to landfill.
Result: The dryer is designed for 36 wet tons per day and produces 5.5 tons of dried product, an 85% reduction in volume and weight. 919-677-8310; www.veoliawatertech.com
