2.2 DESCRIPTION OF THE GREYWATER TREATMENT PLANT INSTALLED IN THE GIZ’S MAIN BUILDING IN ESCHBORN/GERMANY – MEMBRANE BIOREACTOR (MBR) TECHNOLOGY (REFERENCE PROJECT) 2.2.1 TECHNICAL DESCRIPTION During the renovation (from 2004 till 2006) of the main building at the headquarters of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH located in Eschborn/Germany a system for the separate collection of urine and brownwater was installed. This system consists of urine-diversion flush toilets, waterless urinals, separate piping systems for urine, brownwater and greywater and tanks for urine storage. The whole research project is called SANIRESCH (SANItär Recycling ESCHborn) (Winker M. , 2011b) and is financed by the Federal Ministry of Education and Research (BMBF) from July 2009 till June 2012. The further project partners are the University of Applied Sciences Mittelhessen (THM), HUBER SE, Roediger Vacuum, RWTH Aachen and the University of Bonn (GIZ, 2011). A general flow chart of the whole project with its treatment of split wastewater streams is presented in Figure 6. One part of this project is greywater treatment via membrane bioreactor to recycle water. Figure 6: Flow chart of project components of SANIRESCH research project; (Winker M. , SANIRESCH, 2011b) In the middle part of the main building a separating tube system for partial wastewater flows as greywater was installed. As shown in Figure 7 the side wings of the structure are provided with conventional sanitary facilities. This means in one-third of the building the separate collection system is installed. 10
Figure 7: Ground plot of GIZ main building; (Winker et al., 2011b) As part of this thesis the technology used in the GIZ main building in Eschborn to purify greywater was investigated. The membrane bioreactor technology (MBR) in the SANIRESCH research project has a role model characteristic and is a method to recycle greywater sot that it can be reused. In the following section, the technique used, is described and explained and represents the performing conditions in the research project. The technology of greywater treatment which is implemented in the GIZ’s office building is based on the technology of membrane bioreactor (MBR) processing. It combines mechanical and biological treatment in one plant. The treatment plant in Eschborn was developed and built by the company HUBER SE. All technical information refers to technology of HUBER SE. The treatment plant is located in the second basement of the GIZ-headquarters main building, in a room with a 21 m 2 floor space. The system consists of 3 basins and a control panel and it has the dimensions of 2200 mm of length, 1500 mm of width and a height of 2200 mm. The system went into operation on 13 May 2011 and a visual impression of the hardware is given in Figure 8. The operation of the plant requires, a stable energy supply and the working temperature not to fall below 12 °C so as to keep the biological processes running.
