Monitoring Biological KPIs

Our scientists specialise in monitoring key performance indicators (KPIs) to anticipate and mitigate potential digester instability. These unique KPI dashboards enable us to identify proactive interventions, maintaining balance while maximising biogas production and organic loading rates (OLR).

Common Tests for Biogas Plant Feedstock and Digestate Samples

To ensure a comprehensive understanding of your AD plant’s performance, our testing program includes a variety of essential analyses:

Feedstock Testing:

1. Total Solids (TS): Measures the total amount of solids in the feedstock.
2. Volatile Solids (VS): Indicates the proportion of organic matter that can be converted into biogas.
3. Chemical Oxygen Demand (COD): Assesses the amount of organic compounds in the feedstock.
4. Biochemical Methane Potential (BMP): Estimates the maximum methane production potential.
5. pH Levels: Ensures the feedstock is within the optimal range for microbial activity.
6. Nutrient Content (N, P, K): Evaluates essential nutrients for microbial growth.
7. Inhibitory Substances: Detects potential inhibitors like heavy metals or ammonia.

Digestate Testing:

1. Total Solids (TS): Measures the remaining solids post-digestion.
2. Volatile Solids (VS): Indicates the efficiency of organic matter breakdown.
3. Chemical Oxygen Demand (COD): Assesses the remaining organic compounds.
4. Ammonia Concentration: Monitors ammonia levels to prevent toxicity.
5. Volatile Fatty Acids (VFAs): Checks for accumulation that may indicate process imbalance.
6. pH Levels: Ensures the digestate remains within the optimal range for microbial activity.
7. Nutrient Content (N, P, K): Evaluates the quality of digestate as a bio-fertiliser.
8. Pathogen Levels: Ensures the digestate meets safety standards for use as fertiliser.

Managed Services for Test Interpretation and Implementation

Testing can be included as part of a managed service contract, where our consultants interpret test results and collaborate with operations teams to implement necessary changes. This comprehensive approach ensures your AD plant operates at its full potential, maintaining stability and maximising efficiency.
