The role of sodium carbonate in PAM coagulation-flocculation for oil acidized wastewater treatment
The pH value of oil acidized wastewater is relatively low (pH = 6.1), which seriously affects the flocculation of polyacrylamide (PAM). NaOH was used to adjust the pH value, but the maximum was only 7.5. The regulation was limited as the Ca in aqueous phase up to 1,350 mg L consumed OH . A novel for...

| description | The pH value of oil acidized wastewater is relatively low (pH = 6.1), which seriously affects the flocculation of polyacrylamide (PAM). NaOH was used to adjust the pH value, but the maximum was only 7.5. The regulation was limited as the Ca
in aqueous phase up to 1,350 mg L
consumed OH
. A novel formulation of Na
CO
+ PAM was proposed to form CaCO
floc core to facilitate PAM coagulation. When the concentration was above 400 mg L
, the PAM precipitation tended to be maximum, followed by NaOH adjustment of pH to 8.0 that could enhance PAM flocculation successively. The sewage sludge (SS) remained and residue oil reduced to 25 mg L
and 34mg L
respectively. The analysis of the species and composition of fatty acids indicated that the coagulation-flocculation selectively effected the sedimentation of saturated fatty acids (SAT). This provides a new idea for recovery of high value-added residual oil. The optimal additive of Na
CO
is expected as promising coagulant aid to improve the PAM coagulation-flocculation of oil acidized wastewater. |
