Planning
Construction work on the wastewater treatment plant in Varsseveld started in the second half of 2003. Based on an extensive system selection study, the decision to construct a membrane bioreactor (MBR) was already taken in 2001. The treatment plant in Varsseveld is the first MBR installation for the treatment of domestic wastewater in the Netherlands.
Construction work took place between the end of 2003 and the end of 2004. The various installations and the control software were tested and completed in November 2004 and the membranes were placed in the installation on 1 and 2 December. After the membranes had been tested, the MBR plant was started up just before Christmas 2004, using sludge from the existing wastewater treatment plant in Varsseveld. In February 2005, the biological start-up process of the MBR plant was completed and the installation was fully operational.
The official opening of the plant will take place on 3 May 2005.
