Abstract
Ultimate disposal of wastewater sludge has long been a problem which
to a large degree has been ignored. Haney (1971) stated that: "Until
process sludge can be handled with minimum environmental impact, we cannot
claim to have a viable wastewater treatment process". The relationship
of sludge disposal to total treatment processes is emphasized by
the fact that sludge handling and disposal represents up to 50 percent
of the total treatment capital and operating costs (Burd, 1968). Processing
of wastewater sludge will, no doubt, receive increased attention
in the future because of environmental concerns for our air, land and
water.
The present technology for processing wastewater treatment plant
sludge is well established and includes conditioning, dewatering, and
disposal. Many of these processes are highly sophisticated and relatively
expensive. Most of the more advanced processes are unsuitable for small
wastewater treatment facilities in Alaska.The work upon which this report is based was supported in part by
funds (Proj. A-033-ALAS) provided by the United States Department of
the Interior, Office of Water Resources Research, as authorized under
the Water Resources Act of 1964, as amended
