City of Prince Albert

The Prince Albert composting facility, is designed by Earth Tech (Canada)
and the Christiaens Group (NL) in order to treat sewage sludge.The facility
is operated by the city of Prince Albert. Much effort is put in to the
design of the aeration system. At the end of the aeration system an
ammonia scrubber and biofilter are incorporated.Woodchips are mixed
through the sludge to improve the ’compostability’. This mixing is done
inside the building due to the extreme temperatures which can be
reached outside (-40ºC).
