Iron flocculation stimulates biogas production in Microthrix parvicella-spiked wastewater sludge por Pradhan, Surendra K., Torvinen, E., Siljanen, H.M.P., Pessi, M., Heinonen-Tanski, H.

“…This laboratory study explores whether ferric chloride (FeCl3 as PIX-111) or aluminium chloride (AlCl3 as PAX-18) flocculation could stimulate biogas production in wastewater sludge contaminated with Microthrix parvicella. In a fermentation process run in three replicates, cumulative methane production was in average about 25 % higher using the iron flocculated sludge than using the aluminium flocculated sludge; this difference was statistically significant (P\0.05) in the subsequent runs of the semi-continuous process. …”
