NORIT AirLift MBR
Abstract
The Ootmarsum wastewater treatment plant (WWTP) is owned by the water authority Regge & Dinkel
(WRD) and is situated in the municipality of Dinkelland (eastern part of The Netherlands). The WWTP must
be modernised, because it discharges the treated wastewater into a water system with considerable ecological
vulnerability. In the restructuring plan the urban water chain/cycle was integrated into an ecological water
management approach.
In cooperation with Grontmij engineering consultants a design study was carried out resulting in the choice
for a so-called hybrid system. Such a system combines a conventional system followed by a sand filter with a
membrane bioreactor (MBR). With a hybrid MBR, the costs can be reduced relatively to those of a complete
MBR plant without making concessions in terms of effluent quality.
After an intensive selection procedure NORIT Membrane Technology (NMT) was selected with the novel
NORIT AirLift MBR system. The construction work of the 650 m3/h plant started in mid-2005 and will be
completed by late 2006; start-up of the full scale will be early 2007.
As preparation for the full scale plant operation an intensive pilot study is currently being performed in
order to develop a start-up protocol, to train operators, to check control philosophies, and to optimise the
overall processing.[attach]16570[/attach]
