Assunto(s): Iron nanoparticles; Anaerobic digestion; Volatile fatty acid
The volatile fatty acid production through transformed organic wastes has been researched since it can be used as a building block for organic compound synthesis. Adding nanomaterials into the reactors helps to boost the acidification stage by strongly degrading biomass through direct or indirect interspecies electron transfer mechanisms. This work aims to show the increase in VFA production by applying zero-valent iron and magnetite nanoparticles into anaerobic digesters. Granular sludge from a beer wastewater industry was used as inoculum, and glucose was used as a carbon source. The main results showed a 53.7% and 50.9% conversion of glucose into volatile fatty acid by applying magnetite and nano-zerovalent iron nanoparticles, respectively. The main conclusions of the presented work evidenced the application of iron nanoparticles as an alternative for volatile fatty acid production.
