Juneau-Douglas Facility Biosolids Incinerator:

The Biosolids Incinerator (located at the Juneau-Douglas Facility) is used to burn the solid waste matter produced in the wastewater treatment processes at both the Juneau-Douglas and Mendenhall facilities. High temperatures are used in the incinerator (picured at below at right) to ensure complete combustion of the waste material, and the exhaust fumes are filtered extensively allowing only water vapor to be released into the atmosphere.

The resulting purified ash is then mixed with water and sent to holding pond where it is allowed to settle naturally. The water from these ponds is then redirected back into the wastewater treatment process.

The entire system is controlled by means of a sophisticated computer system (pictured at right) that monitors temperatures and flow dynamics throughout the various parts of the wastewater treatment process.
