Inefficient operation waste water treatment plant

The operations of the WWTP can be more efficient.

Fast accumulation of sand in settlement storage basins in wastewater treatment facilities.


Horizontal drain sandcatcher

The horizontal drain sandcatcher is a right-angled container in which the flow speed can be controlled. This makes it possible to make the sand settle more efficiently to the bottom, while the water keeps flowing.


  • Reduces the amount of sand blockages.
  • Prevents the reduction of volume in reactors.
  • Causes less sand to be present in the surplus sludge.
  • There are options available for depth that reduce the expected fluctuating water flow.
