Determining the volatile fatty acid equivalent in thermophilic aerobically digested sludge supernatant

, : Determining the volatile fatty acid equivalent in thermophilic aerobically digested sludge supernatant. Journal of Environmental Engineering 130(4): 397-407

Thermophilic aerobically digested (TAD) sludge supernatant has been found to be a potential carbon alternative for biological nutrient removal (BNR) enhancement in wastewater treatment plants. Carbonaceous substrates, other than the volatile fatty acids (VFAs) in TAD supernatant, were also found to be utilizable in BNR enhancement; however, these carbon compounds could not be detected by conventional chemical analyses (e.g., gas chromatography).

Background: At present, the determination of dry weight in patients on hemodialysis is largely made empirically by trial and error. Extracellular volume (ECV) assessment by bioimpedance analysis (BIA) is a preferable technique for determining dry...

Little or no simian virus 40 (SV40) late mRNA accumulates in the cytoplasm when the primary transcript lacks an excisable intervening sequence. To begin to understand why, we analyzed the synthesis, processing, transport, and stability of SV40 lat...
