|Lime Post Treatment|
When it comes to sludge, dryer is better; and that is precisely what the Charter Machine Company Lime Post Treatment Modules achieve. By adding an alkaline additive or kiln dust to sludge after initial processing, the Lime Post Treatment Modules further de-waters it, creating a dry, crumbly lime-slude mixture that will not clog equipment and is easy to haul and land fills or spread on farm land.

Lime Post Treatment Modules can be added to existing equipment at current facilities.
