IAI can provide coal ash dewatering services, handling dredged ash from a pond, or accepting flow directly from your plant’s wet ash discharge. We will work with you to select a dewatering process that is most appropriate for your particular facility, based on the method of final disposal, proximity to a coal ash landfill, and available space.

Do you have a coal ash landfill on site, or nearby?

IAI can dredge or pump coal ash slurry directly into geotextile tubes placed in an ash landfill (up to distances of ten miles), eliminating the need for hauling the dewatered material to a final disposal site.

Do you need to dewater and temporarily store dewatered coal ash while you transition to another process or upgrade existing facilities?

Geotextile tubes can also be used for temporary ash storage.  IAI can design and construct a lined dewatering pad for staging and filling the geotextile tubes.  The dewatered tubes can later be removed for final disposal of the ash material at the plant’s convenience.

Do you need to quickly dewater and remove wet ash from your site?

IAI can utilize a mechanical dewatering process, such as a thickening and screening system, or belt filter presses, to dewater coal ash for immediate hauling and disposal off-site.
