| Abstract: | This paper presents an analysis of the characteristics of the formation of silicic acid and silicate in flocculation process, an investigation of the treatment on electrolytic manganese waste water, a comparison between the new method and conventional calcium hydroxide precipitation. The results shows that the new method of sodium silicate-calcium hydroxide precipitation has kept the advantages of calcium hydroxide precipitation, and has given up all it's short-comings. |
