Technology Review of Constructed Wetlands - Subsurface Flow Constructed Wetlands for Greywater and Domestic Wastewater Treatment
Author: Hoffmann, H., Platzer, C., von Münch, E., Winker, M.
Publisher: Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ)
This booklet focuses on treating domestic/municipal wastewater or greywater with subsurface flow constructed wetlands with coarse sand as a filter medium. The emphasis is on the application in developing countries and countries in transition. In the publication, an overview and basic guidance is provided on the design and maintenance of horizontal flow beds (HFBs), vertical flow beds (VFBs) and the “French System”. A description of the most common pre-treatment systems is also included due to their vital importance for the proper functioning of CWs. The target audience are people with some basic technical background who want to obtain an overview of subsurface flow constructed wetlands, their designs, performance and maintenance requirements.
The work for this publication was funded by the Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GmbH on behalf of the German Ministry for Economic Cooperation and Development (BMZ).
