Biogas Production From Cow Manure

This dataset was granted by professor Jackson Milano, from Universidade Positivo, as part of his essay with BGS domestic biodigestors, in a ranch, for 14 months, experimenting 4 different biodigestor configurations to obtain continuous biogas production from cow manure all over the year in south of Brazil.

About the settings and tests

Settings used on his experiments:

• bio 1: biodigestor 1 straight to the ground with NO insulation
• bio 2: biodigestor 2 insulated from the ground

Timeline of tests/settings and main events:

1. test 0: may21 - oct21 (bio1)
2. test 1: nov21 - feb21 (bio1 + bio 2 installation)
3. test 2: 22-mar-06 to 22-mai-06 (bio 1 + bio 2 + gas recirculation 20s/hour)
4. test 3: 22-mai-07 to 22-jul-07 (bio 1 + bio 2 + gas recirculation 40s/hour)

File information

Column names and general information:

• Data: date
• Hora: hour
• umidAmb: air humidity (Umidade ambiente)
• tempAmb: air temperature in celsius (temperatura ambiente)
• tempSubst: efluent temperature in celsius (temperatura do substrato)
• tempSolo: ground temperature in celsius (temperatura do solo)
• umidGas: biogas humidity (umidade do biogás)
• tempGas: biogas temperature in celsius (temperatura do biogás)
• decDeBiogas: biogás production dm3 (decímetros cúbicos de biogás produzido)
• volumeTotal: daily total volume produced (volume total produzido no dia)

Other details:

• Columns with no suffix at all are for bio 1
• Columns with suffix "B2" (nov/21 onwards) refers to bio 2 (measurements from both biodigestors combined in a single file)
• 998 and 999 values are sensor errors and should be ignored/removed
