Biogas Production from Arthrospira platensis Biomass

Biogas production by fermentation is a relatively low-cost and simple method for the transformation of substrate into an energy carrier with wide range possible applications. The aim this study was to determine potential Arthrospira platensis biomass as source bioenergy produced during anaerobic digestion (AD). studies were carried out on fractional-technical scale. yield composition analyzed function amount subjected digestion, dosing frequency in digester use pre-hydrolysis mixing compartment. efficiency process also compared each sample. In addition, conversion power index developed determined. It found that A. had significant potential, biogas obtained its calorific value changed depending applied treatments. maximum cumulative 505 L kg−1 volatile solids (VS), while average methane (CH4) content 67.32%. A two-fold increase organic loading rate from 1 g VS·L−1 (VS) 2 positive effect concentration. highest AD VS·L−1, single feedstock input digester, single-stage (2/s/-), ratio under same conditions (1/s/-). Moreover, microalgae higher conventional substrates used plants. This analysis can support selection cogeneration engines plant help output plant, especially varying heat demand.
