Use of Kiln Dust with Quicklime for Effective Municipal

Use of Kiln Dust with Quicklime for Effective Municipal

A series of experiments has provided data which indicate that treatment of municipal wastewater sludge cakes with 35 % kiln dust (cement, CKD or lime, LKD), alone or with a small amount of quicklime, will reduce the pathogenic microbial population in the sludge to below the U.S. Environmental Protection Agency's (USEPA) Process to Further Reduce Pathogens (PFRP) standard (USEPA, 1989).

Agricultural lime is the most commonly used product for increasing soil pH in pastures and is usually the most cost-effective. Limes from Southern Victoria are generally ‘softer’ and tend to partially dissolve in water compared with ‘harder’ limes of other regions; Burnt lime (also called quick lime) is calcium oxide (CaO). It is a faster-acting lime and has the highest neutralising value.

Apr 23, 2021 Lime kiln dust (LKD), is derived during the quicklime manufacturing process as a co-product. It is made up of the finely sized particles that are captured in the baghouse at a lime plant. These particles are high calcium or dolomitic lime plus pozzolans from the fuel used to fire the lime kiln. Because it contains both lime and pozzolans, LKD is a hybrid between lime and cement.
