PASCO, Wash. – Tri-Cities Airport has launched an innovative pilot program using worms to treat deicing wastewater, said the airport in a release.
Partnering with BioFiltro, the airport said it will address environmental concerns by employing a sustainable, energy-efficient treatment system for deicing fluid, which contains potentially harmful chemicals.
Worms play a crucial role by aerating, converting nutrients, and maintaining essential biofilm.
Traditionally, the airport has relied on the Pasco Wastewater Treatment Facility for disposal, but with increasing airline activity, the airport said it wants to manage potential disposal challenges by treating wastewater onsite.
Airport Director Buck Taft expressed excitement about the project, stating, “It sounds strange to use worms to treat deicing fluid, but we’re excited to tap into this innovative, sustainable way to manage a necessary aviation product.”
After the 180-day trial, Tri-Cities Airport and BioFiltro plan to evaluate the potential for a full-scale system, aiming to set a new industry standard in wastewater treatment.
