Due to an increasing supply of industrial wastewater from the Oosterhorn industrial area in Farmsum, near Delfzijl, North Water Afvalwater (NWA) wants to expand the current central facility for wastewater treatment. An industrial water pumping station and a demineralised water installation (DWI) will also be installed due to the water demand for the production processes.
To achieve this, NWA has started the Sustainable Water Supply Delfzijl (DWD) project.
Within this project, Witteveen en Bos and NWA have drawn up 7 work packages.
RWB has received the order from NWA for work package 5. Chemistry and 6. MBR. After an engineering phase in the construction team, in which the DO was jointly drawn up, the projects have now entered the realization phase.
Chemistry work package concerns chemical storage and dosing for the WWTP and the DWI.
14 storage and dosing installations are deployed in separate 10 ft containers, spread over the WWTP and the DWI. For the WWTP, a caustic soda dosage is placed in a 40ft container with a 25m3 storage tank.
Work package MBR concerns the UF membrane installation and is the final treatment step of the WWTP.
The sludge water separation takes place in the MBR. This is done by means of submerged plate membranes. The thickened sludge from the MBR is returned to the aerobic reactor. The clean UF filtrate is discharged into the Seaport Canal.
