Abstract

Hundreds of thousands of tons of cement kiln dust (CKD) as well as other emissions are
generated annually from existing cement plants in Iraq. Most plants dispose of CKD near
or around the plants site as uncovered mounds and piles with significant economic and
environmental impacts. The amount of generated CKD is found to be variable among
different cement plants. It can be estimated that the generated CKD on the average is about
(8-33) % of the production output depending on the conditions of each plant.
An experimental laboratory work on one of the beneficial uses of CKD was carried out in
this study. CKD was mixed with sewage sludge as dry alkaline stabilizing agent. Sludge
treated with CKD was found to meet the class A requirements (fecal coliform density less
than 1000 MPN/g solid) as set by USEPA. In this study, the fecal coliform density of
thickened sludge treated with 20 % CKD was reduced from 2.43×108 MPN/g to 410
MPN/g, while; for dewatered sludge treated with 30 % CKD, it was reduced from 8.75×107
MPN/g to 220 MPN/g. CKD was successfully applied to destroy pathogens, reduce vector
attraction and bring the sludge to a manageable form
