Carbon audit and cost analysis of an innovated wastewater resourcing system by process simulation
نویسنده
چکیده
An innovated wastewater resourcing system (WRS) was formal proposed to couple the production of polyhydroxyalkanoates (PHAs) and electricity generation by microbial fuel cell (MFC) with the proper controlled acidification digester. This paper gave the carbon audit and cost analysis of WRS to estimate its carbon emission, energy saving and profit production. Results showed WRS extracts 18% of influent carbon source and thus lowered energy consumption, excessive sludge discharge and carbon emission from traditional nutrient removal process. Three ways to utilize the carbon source were estimated to give the theoretical profits, alluding the possibility of wastewater resourcing.
