Sampling method and measurement of volatile solids

Volatile solids are measured before anaerobic digestion by sampling all the mixed inputs in the hydrolysis vessel.

Volatile solids are measured after anaerobic digestion by sampling the digestate before it is treated in any way.

The time lapse between sampling before and after anaerobic digestion must match the average retention time specified by the manufacturer of the vessel.

The frequency of the sampling campaigns is established in a way that ensures that 50% of anaerobic digestion cycles are sampled during the reporting period, rounded up.

Samples must be taken and stored in accordance with the most recent version of the section on the analysis of inorganic chemical parameters set out in the Protocole d’échantillonnage de matières résiduelles fertilisantes et dispositions particulières liées à l’accréditation (DR-12-MRF-02) published by the Centre d’expertise en analyse environnementale du Québec at the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs.

The analysis of the volatile solids rate must be conducted by a laboratory accredited by the Centre d’expertise en analyse environnementale du Québec at the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs in accordance with the most recent version of the Méthode d’analyse MA.100-S.T.1.1 it publishes.

For each anaerobic digestion cycle sampled, the CH4 conversion factor is calculated using the following equation:

MCFi	=	(VSbefore – VSafter)
		VSbefore

Where:

MCFi = CH4 conversion factor measured during sampling episode i;

i = Anaerobic digestion cycle sampled;

VSbefore = Average quantity of volatile solids measured in organic materials before anaerobic digestion, in grams per kilogram of wet organic matter;

VSafter = Average quantity of volatile solids measured in digestate after anaerobic digestion, in grams per kilogram of wet digestate.

The lower limit of the 95% confidence interval for the average CH4 conversion factor measured during the reporting period is used to replace the default value for the MCFdigester default value in Equations 9 and 11.
