Abstract
Some of the engineering properties that most strongly influence the disposal of double alkali flue gas desulfurization sludge in a settling pond and the subsequent reclamation of the site for some useful purpose are evaluated. Examined in this test program are the effects of codisposing of fly ash with the sludge, the addition of different stabilizing agents (lime and cement), changes in the concentration of solids, and differences in the curing time on the engineering properties of the sedimented slurries. An analysis of the sedimentation test results for slurries with various fly ash contents and a solids concentration of 15% indicated that the downward velocity of the suspension/clear liquid interface was about one foot per hour.
