Description: Das Projekt "Grey water treatment in upflow anaerobic sludge blanket (UASB) reactor" wird vom Umweltbundesamt gefördert und von Technische Universität Hamburg-Harburg, Institut für Abwasserwirtschaft und Gewässerschutz B-2 durchgeführt. In ecological sanitation, the wastewater is considered not only as a pollutant, but also as a resource for fertiliser, water and energy and for closing water and nutrients cycles (Otterpohl et. al., 1999; Otterpohl et. al., 2003; Elmitwalli et al. 2005). The ecological sanitation based on separation between grey and black water (and even between faeces and urine), is considered a visible future solution for wastewater collection and treatment. Grey water, which symbolises the wastewater generated in the household excluding toilet wastewater (black water), represents the major volume of the domestic wastewater (60- 75 percent) with low content of nutrients and pathogens (Otterpohl et. al., 1999; Jefferson et al., 1999; Eriksson et al., 2002). Most of grey-water treatment plants include one or two-step septic-tank for pre-treatment (Otterpohl et al., 2003). The grey-water treatment needs both physical and biological processes for removal of particles, dissolved organic-matters and pathogens (Jefferson et al., 1999). Recently, many researchers have studied the grey-water treatment either by application of high-rate aerobic systems, like rotating biological contactor (Nolde, 1999), fluidised bed (Nolde, 1999), aerobic filter (Jefferson et al., 2000), membrane bioreactor (Jefferson et al., 2000), or by application of low-rate systems, like slow sand filter (Jefferson et al., 1999), vertical flow wetlands (Otterpohl et. al., 2003). Although high-rate anaerobic systems, which are low-cost systems, have both physical and biological removal, no research has been done until now on grey water in these systems. The grey water contains a significant amount (41 percent) of chemical oxygen demand (COD) in the domestic wastewater (Otterpohl et al., 2003) and this amount can be removed by the highrate anaerobic systems. Although high-rate anaerobic systems have been successfully operated in tropical regions for domestic wastewater treatment, the process up till now is not applied in lowtemperature regions. The COD removal is limited for domestic wastewater treatment in high-rate anaerobic systems at low temperatures and, therefore, a long HRT is needed for providing sufficient hydrolysis of particulate organic (Zeeman and Lettinga, 1999; Elmitwalli et al. 2002). The grey water has a relatively higher temperature (18-38 degree C), as compared to the domestic wastewater (Eriksson et al. 2002), because the grey water originates from hot water sources, like shower (29 degree C), kitchen (27-38 degree C) and laundry (28-32 degree C). Therefore, high-rate anaerobic systems might run efficiently for on-site grey water treatment, even in low-temperature regions. The upflow anaerobic sludge blanket (UASB) reactor is the most applied system for anaerobic domestic waster treatment. Accordingly, the aim of this research is to study the feasibility of application of UASB reactor for the treatment of grey water at low and controlled (30 degree C) temperatures.
