The water bath separator is a stationary, or mobile, installation for separating the light fraction from construction and demolition pre-screened material.
The water bath separator consists of a water-filled tank that features an integrated STARSCREEN® to separate floating materials, and a conveyor to discharge non-floating material. The dimensions feeding the water bath separator are generally > 10mm and < 250mm. Due to an upstream waterflow, the lighter materials are removed and travel over a double-deck fine screen where the water is taken out and the materials fall into a residue bunker at the end of the screen. The heavier material is transported by an incline chain conveyor to the granulate bunker, or can be sent over a quality control sorting line, for a final check for materials, such as PVC etc.
