TY - JOUR A1 - Kleckers, Jonas A1 - Abadi, Abbas A1 - Brandherm, Katrin Marie A1 - Haberkamp, Jens T1 - Wastewater generation model to predict impacts of urine separation on wastewater treatment plants JF - Water Science & Technology 89 (5) N2 - Wastewater treatment plants (WWTPs) are under increasing pressure to enhance resource efficiency and reduce emissions into water bodies. The separation of urine within the catchment area may be an alternative to mitigate the need for costly expansions of central WWTPs. While previous investigations assumed a spatially uniform implementation of urine separation across the catchment area, the present study focuses on an adapted stochastic wastewater generation model, which allows the simulation of various wastewater streams (e.g., urine) on a household level. This enables the non-uniform separation of urine across a catchment area. The model is part of a holistic modelling framework to determine the influence of targeted urine separation in catchments on the operation and emissions of central WWTPs, which will be briefly introduced. The wastewater generation model is validated through an extensive sampling and measurement series. Results based on observed and simulated wastewater quantity and quality for a catchment area of 366 residents for two dry weather days indicate the suitability of the model for wastewater generation and transport modelling. Based on this, four scenarios for urine separation were defined. The results indicate a potential influence of spatial distribution on the peaks of total nitrogen and total phosphorus.

Durch eine starke Verminderung der Durchlässigkeit der Geokunststoffe in Kombination mit einem hohen hydrostatischen Druck wurden unter anderem die Deckschichten verschiedener Deckwerke in den tidebeeinflussten Wasserstraßen Ems und Weser angehoben und beschädigt. Bisher wurden die Milieubedingungen, d.h. Grundwasser- und Oberflächenwasserbeschaffenheit sowie Aquifer- und Deckwerksmaterial, unter denen die Ockerbildung in geotextilen und mineralischen Filteranlagen auftritt, noch nicht systematisch untersucht. Im Rahmen des vorliegenden Beitrags werden im ersten Schritt aus theoretischen Untersuchungen und Datenanalysen von Grundwasser- und Oberflächenwasseruntersuchungen Kriterien zur Bewertung der Verockerungsneigung abgeleitet. Diese Kriterien bzw. DOCP (decisive ochre clogging parameters) zeigen in den Ästuaren Ems, Weser und Elbe Beträge an, die Verockerungserscheinungen begünstigen bzw. ermöglichen. Auf Basis dieser Untersuchungen werden im zweiten Schritt Randbedingungen für zukünftige systematische in-situ Untersuchungen an wasserbaulichen Filteranlagen sowie im experimentellen Modell abgeleitet.

The paper develops the ResourcePlan as (i) legal and (ii) a planning instrument to support the efficient use of resources in urban neighborhoods. The integrative, multi-methodological approach addresses the use of natural resources in the building and infrastructural sectors of (i) water (storm- and wastewater) management, (ii) construction and maintenance of buildings and infrastructure, (iii) urban energy system planning, and (iv) land-use planning. First, the development as legal instrument is carried out, providing (i) premises for integrating resource protection at all legal levels and (ii) options for implementing the ResourcePlan within German municipal structures. Second, the evaluation framework for resource efficiency of the urban neighborhoods is set up for usage as a planning instrument. The framework provides a two-stage process that runs through the phases of setting up and implementing the ResourcePlan. (Eco)system services are evaluated as well as life cycle assessment and economic aspects. As a legal instrument, the ResourcePlan integrates resource protection into municipal planning and decision-making processes. The multi-methodological evaluation framework helps to assess inter-disciplinary resource efficiency, supports the spatial identification of synergies and conflicting goals, and contributes to transparent, resource-optimized planning decisions.

T1 - Potential and risks of water reuse in Brandenburg (Germany) – an interdisciplinary case study JF - Water Reuse 14 N2 - For Brandenburg, a region in Germany with increasing water shortage and drought events, water reuse can counteract competition scenarios between drinking water supply, agricultural irrigation, and industrial use. Centralized and decentralized sources for reclaimed water are found to potentially substitute 245 or 28% of irrigation water, respectively, in agriculture production in Brandenburg. For such a reuse scenario, the fate of organic micropollutants is examined for diatrizoate (DZA) and carbamazepine (CBZ). Retention in local sandy soil and transfer into roots and leaves of arugula are analyzed in lysimeter studies and greenhouse pot experiments. Vertical transport was found for DZA and accumulation in or on arugula roots with a root concentration factor of 1,925+34% but a low bioconcentration factor due to intrinsic molecule properties. CBZ was not found to be mobile in the sandy soil but accumulates in arugula roots and leaves by factors of 70+7% and 155+12%, respectively. Further research on potential plant uptake and groundwater enrichment for more substances is highly recommended as well as tertiary wastewater treatment prior to water reuse.
