Lime Kiln Dust / LKD is a byproduct of lime manufacturing. Lime is created when high quality, natural deposits of Limestone, or calcium carbonate (CaCO3) is subjected to extreme heat. During this progression the extreme heat causes the limestone to chemically release carbon dioxide (CO2). The end result is lime and a byproduct called Lime Kiln Dust or LKD. This product LKD is added to the dewatered sludge cake to: Alter the characteristics of biosolids by increasing stability & reducing pathogens; Meet 503 Regulations for Biosolids Treatment; and increase the pH properties for economical odor control and compliance with EPA regulations for beneficial use & disposal.
