In optimization, minimum methane selectivity is obtained as an aim.
The maximum methane production was 2.04 mg/(L wastewater day) and the minimum methane production was 0.93 mg/(L wastewater day).
These analyses revealed a monotonic increase in the methane fraction and decreases in the ethane and propane fractions during each operation until a quasi-steady state was established.
The maximum methane yield (310.77 mL CH4/g COD) was obtained at an initial pH of 7.0, while the minimum methane yield (34.44 mL CH4/g COD) was obtained at an initial pH of 10.0.
Typical biogas generation capacity for this plant is in the range of 80 to 160 NMSWMg MSW and typical methane fraction in the biogas is 0.6.
Performing a parametric study and to meet a given minimum solar fraction with the lowest cost.
Read mapping was performed using the CLC Genomics Workbench, version 6.0.1 (CLC bio A/S, Aarhus, Denmark), with a minimum length fraction of 0.9 and minimum similarity fraction of 0.95.
The following criteria were used to filter the unique sequence reads: minimum length fraction of 0.9; minimum similarity fraction of 0.8; maximum number of two mismatches.
The RNA-seq analysis tool included in the CLC Genomic Workbench was used for this purpose (minimum length fraction and minimum similarity fraction were set at 0.75 and 0.95, respectively).
Quantitative analysis was performed using CLCbio (CLC Genomics Workbench 4.8, parameter settings: minimum length fraction, 0.5; minimum similarity fraction, 0.95; maximum number of hits for a read, 10).
