Two cities team on solution to produce Class A biosolids amidst mounting regulatory limits for land application of Class B biosolids
(The Woodlands, TX) Therma-Flite, a leading provider of resource recovery technology and services, today announced that it was awarded a contract to provide a biosolids drying system for a Wisconsin sewerage commission. Funded by a low-interest loan from the Clean Water Fund, the project is a joint effort by two cities to upgrade from Class B, to Class A biosolids of exceptional quality (EQ). Two main goals of the upgrade include helping alleviate a phosphorus-based pollution issue in their water streams and solving the problematic restrictions and diminishing acreage available for land application of Class B biosolids.
“We are seeing mounting pressures on municipalities around the country to upgrade to Class A biosolids due to increasing regulatory limitations on land application of Class B biosolids” explains Peter Commerford, VP Sales for Municipal Drying Technology at Therma-Flite and a leading expert on biosolids management. “The Therma-Flite drying system was selected because it proved out to be the best fit due to the need for a cost-effective solution with a modest footprint that fits into existing buildings at the WWTP. Therma-Flite’s unique sealed drying chamber design provides ultra-low oxygen conditions for improved safety and very low off-gas flows for economical odor control.” The engineering company consulting on the project conducted the technology assessment and presented its recommendation report for the dryer to the Public Utility Commission. A compelling fact influencing the final decision was that Class A biosolids can be applied anywhere and is a very effective fertilizer for golf courses and landscaping.
