The RoK4 consists of a vertical perforated screen basket and a shafted auger in a vertical tube. The wastewater flows through an inflow connection and a chamber into the screen basket. Within the screen basket the flights of the screw are equipped with wear-resistant brushes for effective cleaning of the screen. As the screenings are gradually elevated by the auger, they are dewatered. The compacted screenings are discharged into a container or endless bagger thus eliminating odour nuisance.


The screened wastewater flows off by gravity or is pumped to a higher level. The filtrate drains through a hose back into the inlet chamber. The top of the inflow chamber is open and serves as an emergency bypass so that the machine can be submerged without problems, e.g. in case of a power failure. The integrated bottom step prevents back-flooding into the sewer system and thus undesired deposits in the incoming sewer.
