Wastewater generation model to predict impacts of urine separation on wastewater treatment plants
(2024)
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.
Potential and risks of water reuse in Brandenburg (Germany) – an interdisciplinary case study
(2024)
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.
Die Rückführung von Prozesswasser aus der Faulschlammentwässerung kommunaler Kläranlagen führt insbesondere durch dessen hohe Ammoniumkonzentration zu einer stofflichen Rückbelastung der Abwasserbehandlung. Zur separaten Prozesswasserbehandlung wurde auf der Hauptkläranlage Münster eine großtechnische Membrankontaktorenanlage mit Vorbehandlung installiert. Es wurden Stickstoffentfernungsleistungen von durchschnittlich ca. 74 % erreicht. Betriebserfahrungen zeigen, dass neben pH-Wert, Temperatur und Volumenstrom insbesondere die Feststoffabscheidung durch die Vorbehandlung des Prozesswassers einen maßgeblichen Einfluss auf den stabilen Betrieb der Membrankontaktorenanlage hat. Mit den Membrankontaktoren konnte aus dem Prozesswasser Stickstoff als Ammoniumsulfatlösung mit einem mittleren Stickstoffanteil von ca. 2,7 % N zurückgewonnen werden.
Wastewater Generation Model to Predict Impacts of Urine Separation on Wastewater Treatment Plants
(2023)
Wastewater treatment plants are under increasing pressure to enhance resource efficiency and reduce emissions into water bodies. Separation of urine within the catchment area may be an alternative to mitigate the need for costly expansions of central wastewater treatment plant. While previous investigations assumed a spatially uniform implementation of urine separation across the catchment area, the present study introduces a modelling framework which allows to determine the influence of targeted urine separation on the operation and emissions of central wastewater treatment plants. The framework includes an adapted stochastic wastewater generation model, the Stormwater Management Model, and Activated Sludge Model No. 3 with Bio-P module (SIMBA#). The entire application is embedded in the R programming language. The model is validated by an extensive sampling and measurement campaign. Preliminary results based on observed and simulated wastewater generation and transport for a catchment area of 436 residents indicate the suitability of the model for wastewater generation and transport modelling, but also show further need for calibration.
Im Zuge des Klimawandels wird der landwirtschaftliche Bewässerungsbedarf auch in Deutschland zukünftig steigen. Die EU-Verordnung 2020/741 stellt Mindestanforderungen an die Wiederverwendung weitergehend aufbereiteten kommunalen Abwassers zur landwirtschaftlichen Bewässerung, um die Nutzung natürlicher Wasserressourcen hierfür zu begrenzen. Die EU-Verordnung wird am 26. Juni 2023 Gültigkeit erlangen und soll in Deutschland in das Wasserhaushaltsgesetz eingebettet und um eine neue Bundesverordnung ergänzt werden. Zentrales Element der Wasserwiederverwendung wird der für jeden Einzelfall zu erstellende Risikomanagementplan sein, der der Minimierung möglicher hiermit verbundener Risiken dient. Als Hilfestellung für die praktische Umsetzung von Wasserwiederverwendung wird die DWA die Merkblattreihe M-1200 veröffentlichen.
