Complete mechanical wastewater treatment for small sewage treatment plants
- Wastewater fine screening
- Grit separation
- Grit classification
A container-mounted ROTAMAT® Micro Strainer removes solid material from the wastewater depending on its bar spacing (e.g. e = 2 mm). Screenings are removed and transported by a screw conveyor. Inside the closed rising pipe, screenings are dewatered and compacted by an integrated press. Subsequently, they are discharged into a container.
The cleaned wastewater flows by gravity into a Coanda circular grit trap. As the Coanda Tulip is fed through a vortex chamber, the wastewater flow gets tangential in addition to a radial flow direction. Air is sucked into the vortex and mixed with the wastewater flow.
The combination of three effects, namely the Coanda effect, the tea-cup effect and the air intake, guarantee that the organic components are kept on the surface and discharged over a weir while the grit settles in the lower trough area. The separated grit is removed through a classifying screw, statically dewatered and discharged into a container.
