Calculations of effluent nutrient concentrations, struvite production, consumption of Mg(OH)2, electricity demand and reactor and decanter volume are included in Supplementary Information. After nutrient removal treatment, brown and grey water are mixed, and aerobic treatment is performed in a side-...
12kAccesses 13Citations Metrics Abstract Wastewater characterization is the basis for process design and operation optimization of wastewater treatment plants (WWTPs). In this work, a comprehensive study of the respirometry method has been performed to evaluate the biodegradable organic matters of wastewat...
Wastewater treatment plants (WWTPs) are known point sources of contaminants of emerging concern (CECs) to the aquatic environment, but current knowledge is mostly limited to well-known chemical structures. In this study, we sought to identify unknown CECs polluting the aquatic environment through a ...
In this study, Aspen PlusÒ soft- ware was used for energy and mass balances calculations, along with the OLI thermodynamic package (OLI System, Inc.) for de- tailed water chemistry speciation. 4. Water treatment subsystems MWW generally requires additional, tertiary treatment to achieve a ...
