The RoDisc® Rotary Mesh Screen is utilised for the separation of fine suspended material within municipal and industrial applications. The modular screen design allows for easy retrofitting of additional filter surface areas to meet the ever increasing throughput requirements. For example within municipal applications with preliminary screening and preceding biological treatment a throughput capacity of up to 1500 m³/h can be achieved with 20 filter discs.

This ultra fine screen works on the basis of the well-proven drum filter principle. The screen consists of horizontally arranged rotating filter discs installed on a central shaft and are submerged by up to 60% with each filter disc consisting of individual stainless steel segments covered with a square mesh. The wastewater to be treated flows through the segments from inside to outside and the filtrate is discharged at the inlet end of the screen.
