During ,treating wastewater, at 0.01 L in test tubes, it was noted that with further increase in time after 10 min there was a drop in the F.A. (%). However, when the ,wastewater, volume was increased from 0.01 to 0.1 and 1.0 L (conducted in glass bottles) a stability in F.A. (%) was observed. The maximum F.A. observed at 5.0 L was 94.76% ± 2.89%.

1/12/2014, · While acidification with ,sulfuric acid, is the universal means of coagulant resolubilization, there is a lack of consensus on the optimum operational pH. More metal coagulant can be solubilized at lower pH values but this effect has been reported to diminish below pH values of 1, at concentrations of approximately 2,500 mg/L Al (Saunders and Roeder, 1991 ).

The effects of reaction time, oxidant concn., oxygen-coal ratio and microwave power on FA yield are detd. ,Sulfuric acid,-acetone was applied to purify the primary FA products. The results indicate that the oxidant concn. is a sensitive factor affecting the yield of FA, while reaction time has little effect.

Marton (1971) recommended a two-stage acidification as a strategy to achieve good filterability. In the first stage the black liquor is acidified with either CO2 or ,sulfuric acid, to a pH of about 9 to 10, and the precipitate is filtered. The precipitate is then resuspended in water and acidified with ,sulfuric acid, …
