The black water loop: water efficiency and nutrient recovery combined Lindner, B. (2008)

Objective of this thesis is to develop a system for purification of black water for its reuse as a toilet flush water, which fulfils all hygienic as well as aesthetic needs (black water loop). Additionally the nutrients contained in the black water stream should be reused, instead to be eliminated in a complex process on a waste water treatment plant. Within this dissertation all necessary purification technologies are selected and tested regarding their applicability. The overall technical feasibility as well as the interaction of all components was investigated and proved by operation of a pilot plant, which was constructed at the Institute of Waste Water Management and Water Protection of the Hamburg University of Technology (TUHH). It was operated over a period of time of approximately 16 months duration. These investigations resulted in four basic statements: Despite high nitrogen concentrations in the inflow a stable biological treatment of black and yellow water with a stable nitrification is possible. Even for this highly concentrated waste water stream the removal of the odour is possible simply by biological treatment.
