US: Charah Solutions has launched a proprietary fly ash thermal beneficiation technology that improves the quality of fly ash. It says that its new MP618Multi-Process technology reduces loss on ignition (LOI), ammonia, activated carbon and moisture in fly ash.

The technology allows for the beneficiation of both wet and dry fly ash. It advantages include lower costs, self-contained environmental controls that can be deployed in weeks, as opposed to years and a modular design that can be scaled up or down to increase production based on market demand.

MP618 can process both wet and dry fly ash. It can be installed at both operating and non-operating power plants, regardless of whether the fly ash is current production or legacy ash stored in ponds or landfills. The technology also allows for the processing of kiln dust to remove mercury for emissions regulations compliance. With the introduction of MP618, Charah Solutions expects to increase its supply of marketable fly ash to concrete producers and add greater value to its utility customers.

“MP618 will expand our MultiSource materials network, a unique distribution system of more than 30 nationwide sourcing locations, and improve our ability to provide a continuous and reliable supply of supplementary cementitious materials, including quality fly ash and slag cement, for ready mix concrete producers and other customers throughout the US,” said Scott Ziegler, Vice President of Byproduct Sales at Charah Solutions.
