Analytical Services Brief Description Cost (per sample)
Biochemical Methane Potential (BMP)

BMP of a sample is measured in a batch reactor containing the anaerobic assay prepared mainly by inoculum, sample, and water. The BMP value of a sample is reported in volume of methane produced normalized with respect to the volatile solids from sample at STP and dry conditions.

Anaerobic Toxicity Assay (ATA)

ATA is a screening test to determine the potential toxicity of substances, mixture of substances, chemicals, and additives by the volume of biogas produced. The duration of ATA test vary based on the tested materials ranging from 3-20 days. The ATA test reports the EC50, half maximum effective concentration of the material tested.

Residual Methane Potential (RPM)

RPM is measured to determine the stability of the digestate under anaerobic conditions to understand the performance of an operating digester, measure the carbon emissions from the digestate stored or land applied. The RPM value of a digestate is reported as the volume of biogas, carbon dioxide, and methane normalized to the volatile solids from the digestate.

Bench-scale AD reactors The experimental set-up of bench scale AD reactors can be operated in semi-continuous and continuous modes to collect preliminary data for full scale AD reactor design. The test can be used to optimize hydraulic retention time (HRT), organic loading rate for maximum methane production and volatile solids removal. This experimental study can be employed to test the compatibility potential co-substrates, to understand the start-up period performance in the digesters, and to observe acclimation to a new additive(s).
