The wastewater flows into the internal part of separator, where it is put in circulation in order to increase separation efficiency – centrifugal force and gravity ensure optimal conditions for the above process.
The separated sand collects in lower, conical part of the device. The separator may be equipped with slow motion mixer, which shovels and mixes sand. Water flushing and compressed air aeration ensures high organic matter removal efficiency. Filtrated wastewater is transferred outside through the outlet stub pipe. The sand collected on the bottom is transported outside with worm conveyor being gravitationally drained in the same time. The separator is equipped with opened cover being a revision hatch in the same time.
