1/1/2014, · The present study proposed the isolation of arsenic resistant bacteria from wastewater. Only three bacterial isolates (MNZ1, MNZ4 and MNZ6) were able to grow in high concentrations of arsenic. The minimum inhibitory concentrations of arsenic against MNZ1, MNZ4 and MNZ6 were 300 mg/L, 300 mg/L and 370 mg/L respectively.

The arsenic-containing off-gas is further treated in a gas washing plant to recover the arsenic. The arsenic-containing off-gas is contacted with an acid to generate an effluent in the form of an acid solution. Conventionally, the acidic gas wash effluent is then neutralized with lime, filtered and dried to produce a calcium arsenate sludge. However, the handling and disposal of such arsenic-containing sludge are …
