Biogas production experimental research using algae

The current study is on the the use of macro-algae as feedstock for biogas production. three types of macro-algae,cladophora glomerata (cg), chara fragilis (cf), and spirogyra neglecta (sn), were chosen for this research. theexperimental studies on biogas production were carried out with these algae in a batch bioreactor. in thebioreactor was maintained 35 ± 1°c temperature. the results showed that the most appropriate macro-algae forbiogas production are spirogyra neglecta (sn) and cladophora glomerata (cg). the average amount of biogasobtained from the processing of sn – 0.23 m3/m3d, cg – 0.20 m3/m3d, and cf – 0.12 m3/m3d. considering theconcentration of methane obtained during the processing of sn and cg, which after eight days and until the end ofthe experiment exceeded 60%, it can be claimed that biogas produced using these algae is valuable. whenprocessing cf, the concentration of methane reached the level of 50% only by the final day of the experiment, whichindicates that this alga is less suitable for biogas production.
