Metallic wastewater treatment by sulfate reduction using anaerobic rotating biological contactor reactor

Mothe Gopi Kiran, Kannan Pakshirajan, Gopal Das

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 4, doi: 10.1007/s11783-018-1073-4

Abstract:

An-RBC reactor is highly suited to treat metallic wastewater.

Metal removal is due to sulfide precipitation via sulfate reduction by SRB.

Cu(II) removal was the best among the different heavy metals.

Maximum metal removal is achieved at low metal loading condition.

Metal removal matched well with the solubility product values of respective metal sulfide salts.
