  This paper discusses how the fate of nitrogen, phosphorus and carbon in wastewater and sludge management affects the environmental performance as it may easily be shifted from a resource to a problem and vice versa. The paper explores the impact of some variations in wastewater treatment technology with resulting shifts of elements between forms and media. To this end, life cycle assessment (LCA) results were calculated for a model municipal wastewater treatment plant with primary settling and secondary treatment, and anaerobic digestion of mixed primary and secondary sludge and subsequent use of the sludge in agriculture (baseline scenario). The effect of changing plant operation to increase nitrogen removal and to add also phosphorus control was studied, using data from mass and energy balances. Further, the paper shows that how data for many flows containing nitrogen, phosphorus an.. Read More»
