A remote submerged chain conveyor system separates particles from a coal ash/water slurry from remotely located boiler units. A tank forms an ash holding section, a dewatering section, and an ash settling section. The ash holding section receives the slurry with first and second opposite ends. The dewatering section dewaters the slurry. The settling zone is an elongated trough connected with the ash holding section at one end with a discharge drain trough at near an opposite end. The tank sections are in a generally linear arrangement. A drag chain moves along the ash settling conveying the particles settling from the slurry to the dewatering section opposite to a net flow of water. A flocculant supply line upstream of the ash settling section configured for adding a flocculant promoting an agglomeration of particles into flocs. The flocculant supply line is located in a mixing section with an agitator.
