DANK Ein besonderer Dank geht an meine Mentorin Dr.-Ing. Martina Winker, die den Themenvorschlag für diese Arbeit im Rahmen des Forschungsprojektes SANIRESCH gemacht und mir durch ihre Betreuungszusage diese Masterarbeit ermöglicht hat. Mit ihrer Diskussionsfreudigkeit und zahlreichen Denkanstößen hat sie meine Masterarbeit begleitet und damit viele Impulse und Anregungen geliefert. Ich möchte mich ganz herzlich bei Herrn Prof. Helmut G. Hohnecker für die Betreuung meiner Masterarbeit im Rahmen der Hochschule bedanken, durch sein Engagement im Bereich neuartiger Abwasserkonzepte wurde mein Interesse für dieses Arbeitsfeld geweckt. Für die Unterstützung bei der GIZ geht ein großes Dankeschön an das ecosan-Team, besonders möchte ich mich bei Amel Saadoun und Enno Schröder bedanken, die mich kontinuierlich mit Daten und Informationen versorgt haben. An die SANIRESCH Projektpartner, die mich in fachlichen Fragen tatkräftig unterstützt haben, geht ein besonderer Dank. Hier möchte ich besonders Johanna Heynemann (THM) und Martin Feicht (HUBER SE) hervorheben. Ein weiterer Dank geht an S. Jakob (greenlife), E. Nolde (Nolde&Partner), M. Sellner (DEHOUST) und meinen Kommilitonen Yue Wu, die mich mit ihrem Expertenrat unterstützt haben. Ganz besonders möchte ich mich bei Julia Seitz und Trevor Surridge für das Korrekturlesen bedanken, in Fragen der englischen Sprache waren sie sehr hilfreiche Ratgeber. Meinem Freund Bernd und meiner Familie danke ich sowohl für die Unterstützung als auch für die Ablenkung während dieser Zeit. I
ABSTRACT In its German headquarters in Eschborn, GIZ installed a greywater treatment system within the research project SANIRESCH. It is based on membrane bioreactor (MBR) technology designed by HUBER SE. Greywater is domestic wastewater excluding toilet water, therefore easily recyclable. Within this work the international transferability of this technology was investigated. Greywater characteristics and legal foundations were obtained by literature study. Different treatment methods were compared and an investigation of existing MBR projects was conducted. The SANIRESCH plant was described and evaluated according to its economic aspects in comparison to a standard application in a hotel. By means of a utility analysis, based on the fundamentals of sustainable sanitation, the potential for international transferability was assessed to detect the crucial issues. In summary, MBR technology for greywater treatment provides an excellent cleaning performance with minimal space requirement, but relatively high energy demand. For office buildings, an economic benefit is rarely achieved, caused by an unfavourable water balance. While residential buildings show beneficial water balance and reimbursement is attainable. Concerning worldwide transferability, environmental aspects based on water scarcity as an indicator criterion, 32 countries were assessed. Due to water shortage, poor water quality, high population density and high urbanisation rate, the MENA region was identified as hotspot. II
