According to the analysis of effluent contents, at pH 5.5, 5.0, 4.0, the effluent contained mostly butyric acid (43.1 56.6%), followed by acetic acid (24.6 29.8%); at HRT 4.17, 6.26, 8.34 h, the effluent contained mostly butyric acid (43.0 53.6%).
The maximum biological efficiency predicted by the model (81.36%) corresponded to the point defined by the effluent contents (X1 = 1), pH (X2 = −1) and fungus species (X3 = 1), specifically 50%, 5.0 and P. floridae, respectively.
Panel d shows the effluent CO2 content changes over time (mixed model: group vs. effluent CO2 content interaction, P = 0.769; timepoint vs. effluent CO2 content interaction, P = 0.136; timepoint vs. group interaction, P = 0.242), for the effluent CO2 content, the baseline data were excluded.
Since the effluent gas content varies with the process, there is no single recovery technic can meet all effluent gas content conditions.
The variation of effluent gas content shows that experiments of WAG mode have higher extent of oxygen addition and bond scission reaction compared with the experimental results of continuous injection mode.
The countercurrent operation requires a significantly smaller area than the co-current operation in the stripping sector at high effluent Cr VI) content.
Myocardial oxygen consumption was determined from influent and effluent oxygen content (measured by blood gas analyzer, ABL-30, Copenhagen, Denmark) and flow rate.
The researchers evaluated the effluents for content of two chemicals previously implicated in causing intersex steroidal estrogens and alkylphenols and found that these levels were similar to concentrations reported in wastewater effluents in the United Kingdom and worldwide.
Whole body oxygen extraction is difficult to measure directly but can be inferred from the difference between the influent and effluent oxygen contents of an organ, or for the entire body.
