For AFBR, the COD removal efficiency was slightly impacted by the HRT.
The average AFBR (IAFMBR) effluent benzothiazole concentrations were 2.03 [+ or -] 0.24 mg/L (1.23 [+ or -] 0.27 mg/L), 9.60 [+ or -] 1.36 mg/L (7.28 [+ or -] 1.36 mg/L), and 12.02 [+ or -] 1.71 mg/L (8.99 [+ or -] 1.89 mg/L) at the HRT of 24, 18, and 12 h.
For AFBR, a lower HRT applied may cause the washout of the functional bacteria that is required for the biodegradation of antibiotics .
Acetate was the major component of VFAs in the AFBR effluent, which increased with the change of HRT, and its concentrations in the AFBR effluent were 88.44 [+ or -] 11.84 mg/L (HRT 24 h), 206.93 [+ or -] 15.58 mg/L (HRT 18 h), and 242.82 [+ or -] 9.55 mg/L (HRT 12 h), being accounted as about 73.31%, 69.98%, and 68.26% of total VFAS, respectively.
The increment of propionate increased slightly, and its concentrations were 15.86 [+ or -] 3.31 mg/L, 18.84 [+ or -] 5.75 mg/L, and 23.01 [+ or -] 0.79 mg/L at the HRT of 24, 18, and 12 h in the AFBR effluent.
In making its determination, the AFBR considered two pieces of evidence that supported a conclusion that the baby took breaths on her own prior to dying.
In Gibson, while the AFBR cited witness testimony and medical evidence to prove that the baby took breaths prior to dying as support for their determination that the child was born alive, they held that the born alive doctrine does not require that the umbilical cord be severed.
