About anaerobic digestion plant operator

The operator feeds the digester with feedstock such as food waste, animal manure, sludge and processing residues, holds the temperature, mixing and retention time, and watches the composition of the feed. Disposal of the food waste arriving at the plant is handled too.

The operator monitors plant production and digester performance, runs quality control analysis — biogas composition, methane and hydrogen sulphide content, pH and volatile fatty acids in the digestate — and decides from that whether to change the feed rate. Biocatalytic processes are developed for new feedstocks.

The operator carries out regular inspections, diagnoses and clears faults — blocked pumps, leaks, mixer failures — and maintains the biogas plant as a whole. Workplace safety measures are applied and health and safety rules observed, because biogas is explosive and hydrogen sulphide is toxic at low concentrations. Formal requirements, such as certificates for work on gas and electrical installations, are set by the employer and by local regulations.

Key Work Functions

Core areas of responsibility for a anaerobic digestion plant operator.

1

Monitor and control biogas production

  • Record daily production metrics including gas volume, pressure, and composition
  • Adjust operational parameters to optimize biogas yield and quality
  • Monitor reactor temperature and maintain optimal digestion conditions
2

Perform equipment maintenance and troubleshooting

  • Conduct routine inspections of digesters, pumps, and piping systems
  • Diagnose and repair equipment failures to minimize downtime
  • Document maintenance activities and equipment performance
3

Conduct quality control analysis

  • Test biogas composition, pH levels, and digestate quality
  • Identify contaminants and implement corrective measures
  • Maintain quality documentation and compliance records
4

Manage waste input and feed preparation

  • Receive and inspect incoming organic waste materials
  • Prepare feed materials and manage input ratios for optimal digestion
  • Ensure proper disposal of unsuitable materials
5

Ensure safety and regulatory compliance

  • Follow all health and safety protocols and wear appropriate protective equipment
  • Conduct safety inspections and report hazards
  • Maintain compliance with environmental regulations and facility standards
