A triple-row sink-float tank for PET uses water to separate the heavier PET fraction from lighter cap material. In the design shown, three rotating screws move plastic through an extended path within the tank.
How three rows extend the separation path
The longer path gives material more time in the water. PET sinks for collection below while lighter material floats, so the two fractions can be sent to separate downstream stages.
