Pilot Plant Nordenham
The city of Nordenham in Lower Saxony (Germany) is part of the supply area of the water company Oldenburgisch-Ostfriesischer Wasserverband (OOWV). It is a region with high water demand by industrial and commercial customers. A large part of the water is needed as so called service water, e.g. as process-, cooling- or cleaning water.
There are only low requirements for the service water needed for irrigation or cooling processes and this water simply is taken from the river Weser. Other processes, however, have higher requirements. Steam power processes for example need demineralized and ultra pure water.
To protect drinking water resources it is now tested how the treated water from the waste water treatment plant can be additionally treated in order to be able to offer different kinds of service water in different qualities and quantities.
The customers from the region as well as the city of Nordenham and the region Wesermarsch support MULTI-ReUse and are very active in the accompanying advisory board.
The water treatment plant of Nordenham
The water treatment plant of Nordenham is run by the Stadtwerke Nordenham, which processes the water of around 36.000 inhabitants. The local and technical circumstances of the water treatment plant are optimal for the implementation and operation of a pilot plant.
The staff of the treatment plant supports the project by providing space and premises.
What is being researched at the pilot plant
New and improved process technologies, mainly in the area of membrane processes – ultra filtration (UF) und reverse osmosis (UO) – are being researched and tested at the pilot plant. Furthermore, methodologies for a microbial monitoring are developed and tested to be able to monitor the quality of the processed service water.
During the operation phase, MULTI-ReUse will provide and qualitatively monitor three service waters in different qualities for different purposes. Another element is the evaluation of the suitability of different types of tube materials for the distribution networks for the particular service waters.
MULTI-ReUse also investigates further application possibilities of global significance beyond the industrial use. At the pilot plant procedures are developed for the use in agricultural irrigation or artificial groundwater recharge. A special focus lies on the removal of anthropogenic – man-made – trace substances.
