Nitrogen and organic load removal from anaerobically digested leachate using a hybrid electro-oxidation and electro-coagulation process

Author(s): Choudhury MR; Rajagopal R; Meertens W; Rahaman MS;

This study evaluated the performance of an integrated electrochemical process, which simultaneously utilizes electro-oxidation (EO) and electro-coagulation (EC) methods while removing organic and nitrogen loads from high-strength leachate obtained from anaerobic digesters. A bipolar arrangement of the aluminum electrode, sandwiched between a monopolar bor ...

Treatment of decentralized low-Strength livestock wastewater using microcurrent-assisted multi-soil-layering systems: Performance Assessment and microbial analysis

Author(s): Liu C; Huang G; Song P; An C; Zhang P; Shen J; Ren S; Zhao K; Huang W; Xu Y; Zheng R;

Discharge of decentralized livestock wastewater without effective treatment has become a common problem in rural areas, threatening the regional water environment. A new microcurrent-assisted multi-soil-layering (MSL) system was developed for treating rural decentralized livestock wastewater. The results showed the highest removal rates of chemical oxygen ...

Electrochemical nutrient removal from natural wastewater sources and its impact on water quality

Author(s): Kékedy-Nagy L; English L; Anari Z; Abolhassani M; Pollet BG; Popp J; Greenlee LF;

In this study, a suite of natural wastewater sources is tested to understand the effects of wastewater composition and source on electrochemically driven nitrogen and phosphorus nutrient removal. Kinetics, electrode behavior, and removal efficiency were evaluated during electrochemical precipitation, whereby a sacrificial magnesium (Mg) anode was used to ...

Using 3D CityGML for the Modeling of the Food Waste and Wastewater Generation-A Case Study for the City of Montreal

Author(s): Braun R; Padsala R; Malmir T; Mohammadi S; Eicker U;

The paper explains a workflow to simulate the food energy water (FEW) nexus for an urban district combining various data sources like 3D city models, particularly the City Geography Markup Language (CityGML) data model from the Open Geospatial Consortium, Open StreetMap and Census data. A long term vision is to extend the CityGML data model by developing ...

Exploring the decentralized treatment of sulfamethoxazole-contained poultry wastewater through vertical-flow multi-soil-layering systems in rural communities.

Author(s): Song P, Huang G, An C, Xin X, Zhang P, Chen X, Ren S, Xu Z, Yang X

Sulfamethoxazole (SMX) is the most widely distributed sulfonamide antibiotics detected in decentralized poultry wastewater in rural communities. As an economically-feasible and eco-friendly technology for decentralized wastewater treatment in rural areas, vertical-flow multi-soil-layering (MSL) system was promising to mitigate the ecological and human hea ...
