dc.description.abstractWhile globally freshwater is becoming an increasingly scarce resource, the local treatment and reuse of greywater is a promising approach to address water scarcity. In the scope of this study, a pilot facility for the recycling of laundry greywater has been examined. With the aim to enable nearly complete energy and water self-sufficiency, the system treats the wastewater within the unit and constantly reuses the water for washing in a closed cycle. The system is based on physical/mechanical pre-treatment and biological treatment in trickling filter columns. The treatment process is operated in batch mode. Furthermore, the facility is powered by a photovoltaic plant (0.9 kWp) with second-life batteries (4 kWh). The facility is designed for up to five washing cycles per day, producing approximately 300 l of wastewater per day. The facility has been operated during an experimental period of ten weeks. Parameters for energy consumption and production, water losses, and water quality were monitored. First results indicate that the system achieved to recover 69% of the used water for the washing machine while treating the wastewater to the necessary water quality levels. Most of the water (26%) was lost in the pre-treatment step due to the skimmer. Therefore, further development will aim to treat the skimmer wastewater and feed it back into the system. By doing so, water self-sufficiency could reach up to 90%. Furthermore, energy self-sufficiency and optimization measures were modelled for one year based on the monitored data from the ten week experiment.de_CH
