RESEARCH AND TESTING OF REDUCTION OF FLUORINE AND PH VALUE IN ASH WATER OF COAL-FIRED POWER PLANTS[J]. Thermal power generation, 1995, (1). DOI: 10.19666/j.rlfd.1995.01.006.
Separate testings were conducted on the densed ash with ash/water ratio of 1:3 and 1:20 to reduce fluorine andpH value.Results show that with aluminum sulfate and flocculent to treat the densed ash water
the content of fluorine inthe ash waer can be reduced from 16-25 mg/1 to 10 mg/1.And the pH value was lowered too.
