Biogas plant automation — PLC and SCADA-based control of anaerobic digester and gas purification systems

Biogas Plant Automation — Maximise Yield, Ensure Safety

Biogas plants involve complex, continuous processes — anaerobic digestion, gas collection, purification, compression and power generation — that demand reliable, real-time automation to operate safely and efficiently at maximum biogas yield.

Adarsh Industrial Automation supplies and commissions PLC-based control systems and SCADA platforms specifically for biogas plants, including digesters, gas upgrading units and combined heat and power (CHP) control integration.

Biogas Process — Where We Automate

Feedstock Handling

Automated feeding, mixing and macerator control with level and flow monitoring.

Digester Control

Temperature regulation, agitator speed, pH and biogas pressure monitoring.

Gas Purification

H₂S scrubbing, moisture removal and gas quality monitoring with automated valve control.

Storage & Compression

Gasholder level management, compressor control and safety interlock systems.

Energy Management

Generator and boiler integration, power metering, energy reporting and alarming.

Energy reporting: biogas yield trends, power generation logs

Scalable architecture — add new digesters without replacing control hardware

Why Biogas Plants Need Specialist Automation

Biogas involves flammable gas in large volumes — automation must incorporate gas-safe enclosures, ATEX-rated sensors where required, and robust safety interlock logic. At the same time, the biological process in the digester is sensitive to temperature swings and agitation speed. A well-designed PLC system maintains stable digester conditions autonomously, reducing operator intervention and maximising daily biogas output.

Our team has commissioned biogas automation across municipal, agro-industrial and food-waste biogas projects and understands both the process requirements and the safety obligations involved.
