Study of Technological Conditions for Fluoride Removal from High Fluoride-Containing Wastewater |
| |
| Abstract: | The moderate technological conditions of fluoride removal from the high fluoride-containing wastewater by coagulation and precipitation are studied.Under the experimental conditions,fluoride removal agent,calcium hydroxide,calcium chlorite and coagulates with polyacrylamide.The concentration of wastewater can be reduced to below 10/mg·L -1 and meets the drainage standard. |
