Dredging company De Boer is currently working at a polluted sludge depot in the Ketelmeer near Dronten using a sand suction dredger.
The National Water Board  dredges the national waterways and ports and then transports the polluted sludge by barge to this depot where it is placed next to the sand suction dredger. The sludge is then mixed with water so that the sand pump can pump it out.


In September, Van Heck provided a quick solution preventing downtime due to a fault in the on-board equipment.
Van Heck supplied a DPPG120-HK400 and the pump was connected to a “tromp”; an adjustable lance that allows the water to be mixed with the sludge in a targeted manner.
This project is still ongoing.
