Ameliorating tannery sludge dewaterability by disintegration of extracellular biopolymers with FeCl3-MnSO4/oxalic acid/sodium percarbonate: Spectroscopic profiling of dissolved organic matter in sludge filtrate

Effectual sludge dewatering techniques are strongly desired by industrial wastewater treatment plants. In this work, we scrutinised the efficacy of various Fenton based complex mediated processes like ferric chloride (FeCl3)/oxalic acid (OA)/sodium percarbonate (SPC) (FOS), FS (without OA), manganes...

Description
Summary:Effectual sludge dewatering techniques are strongly desired by industrial wastewater treatment plants. In this work, we scrutinised the efficacy of various Fenton based complex mediated processes like ferric chloride (FeCl3)/oxalic acid (OA)/sodium percarbonate (SPC) (FOS), FS (without OA), manganese sulphate (MnSO4)/oxalic acid (OA)/sodium percarbonate (SPC) (MOS) and MS (without OA) for which capillary suction time (CST) was attained as follows: MS (204 s)
