Groundwater treatment sludge (GWTS) is a Mn-rich waste and precipitated from backwash ,wastewater, of groundwater treatment plants. Approximately, 5 t of sludge is generated in treatment plants with a production of 80,000 m 3 /d. The sludge contains 5.4–8.5 wt % of Mn and is usually dumped directly into the river or sea without disposal. With such disposal, the sludge was precipitated on the ...
