In this work, a brief assessment of using microalgae (Arthrospira platensis PCC 8005) for lowering carbon emissions during biotrickling filtration of volatile organic compounds (VOCs) from air is performed. In this regard, the removal efficiency of acetic acid vapors (used as model VOC in this study) and carbon dioxide production from this process are evaluated in the presence of: (1) classical microorganisms (e.g. from compost), (2) mixture of compost microorganisms and microalgae, (3) microalgae. A blank trial (...

In this study, a classical biotrickling filter (based on compost microorganisms) and an upgraded biotrickling filter (based on a mixture of compost microorganisms and microalgae Arthrospira platensis PCC 8005) are evaluated in terms of carbon dioxide production, during their use for volatile organic compounds (VOCs) removal from air. The experiments were performed using acetic acid vapors as model VOC and the biotrickling filter (BTF) performance was observed at different VOC concentrations, gas flowrates and pH v...
