For skimming of slow sand filters

Skimming of slow sand filters without emptying has long been a request from the water market. Weda is now launching a remote-controlled robot that can run on the sand bed and remove the so-called schmutzdecke and pump it to the desired landfill. The machine sucks in 1-3 cm of schmutzdecke and the sand that is pumped out of the slow filter. The method also works on facilities with infiltration ponds. The estimated cleaning capacity is 60-150 square meters per hour.

The advantages with our method of cleaning:

  • Environmentally friendly - no emissions during cleaning
  • The filter does not need to be emptied of water - the time the filter needs to be taken out of operation is radically reduced
  • Reduced risk of affecting the microflora because the filter is not laid dry
  • All oils are food approved
  • With a robot in place, the skimming can be done directly if necessary and possibly more often than today to ensure the supply of drinking water
