Revisiting Entex Treatment at Woburn Superfund Site – Six Years Later
In December of 2016 Entex’s Webitat submerged fixed film installation at the Superfund site at Woburn, MA started up. Eighteen Webitat units were installed, anchored on a specially built pier in this lagoon. The original objective was to remove ammonia from the system. While the treatment objectives were complex, involving a formula to include temperature and alkalinity, generally we needed to treat to below 1 mg/l of ammonia.
