چکیده انگلیسی
This research evaluates possible water impacts arising from creation of potent wastewaters during hydrothermal liquefaction (HTL) of organic wastes. Aqueous co-products (ACPs) arising from HTL of eight feedstocks contained very high concentrations of traditional wastewater pollutants: 100-3300â¯mg/L total nitrogen (N), 45-3600â¯mg/L total phosphorus (P), and 16,000-234,000â¯mg/L chemical oxygen demand (COD). pH was 4.4-8.8. These characteristics render ACP more noxious than relevant benchmark wastewaters. Adjustment of published energy ratio metrics to account for ACP treatment reveals that energy yield is moderately decreased, and energy consumption for COD, TN, and TP removal is of the same order of magnitude as liquefaction. Recovery of valuable nutrients (i.e., N and P) from ACP via precipitation could reduce the energy intensity of ACP management and mitigate its impact on energy recovery. In particular, precipitation-based nutrient recovery could enhance HTL's appeal as means to valorize waste into renewable energy and valuable scarce materials.
