Separation of PET parts from washing water

A plastic recycling company producing polypropylene granulates from post-consumer plastics uses two Börger Bioselect RC 75 in its plant. The two Bioselect units separate plastic residues from the washing water. Reducing the residual water content helps to save a lot of energy in the recovery process.

Before purchasing the Börger separators, the plant had already tested several devices. The Bioselect reduced the residual water content to less than 20 %, whereas a residual water content of almost 50 % was measured in the plastic residues following separation by the other devices.

The two Bioselect RC 75 are integrated in the process. Due to process-related circumstances, the process flow feeding the Bioselect cannot be regulated. A control unit automatically adjusts the speed of the separators to the volume of the feed flow and the solids content contained therein. This ensures that the two separators always operate at their optimal capacity.

The operator of the recycling plant is very satisfied with the two Börger separators as they are very energy-efficient. The customer was impressed by the high dewatering degree and the long service life of the separators.
