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
