A process is developed wherein sodium carbonate is reclaimed from Trona-treated fly ash waste stream, and the fly ash rendered suitable for use as a Pozzolan. The process is a closed system wherein all separated aspects of the waste stream are reused by the generating power plant or offered as a commercial product.

Disclosed are a system and a process for preparing a refined sodium carbonate solution. The system includes a formulation tank for dissolving an industrial-grade sodium carbonate; a feeding mechanism, an outlet of which is connected to an inlet of the formulation tank; a pH regulator, the pH regulator being disposed in the formulation tank, and the feeding mechanism being connected to the pH regulator; a filtering mechanism, an inlet of which is connected to an outlet of the formulation tank; and an adsorption mechanism, an inlet of which is connected to an outlet of the filtering mechanism.
