City of Anacortes, WA

In 1992, the City opened the secondary wastewater facility with a capacity of 4.5 million gallons per day. The Anacortes Wastewater Treatment Plant takes the raw primary and secondary solids from wastewater, blends it, and thickens it. The thickened material is conditioned with polymer and dewatered on a belt filter press. The dewatered material is incinerated in a fluidized bed incinerator reducing the volume by roughly 80%.
