METALLOID CONTAMINATED WATER SOLUTION PURIFICATION PROCESS FOR SAFE HUMAN CONSUMPTION-RATED REDUCTION OF CONTAMINANT CONCENTRATION THEREIN, BY PRECIPITATION WITHOUT OXIDATION |
摘要 |
A metalloid contaminated liquid water solution purification process providing decrease to safe human consumption-rated levels of metalloid concentration therein, by precipitation without oxidation and without liquid water heating. The process comprises the following steps: injecting a ferric iron coagulant; injection of lime in the liquid solution; precipitating the metalloid; separating the resulting slurry between a liquid and a solid phase, wherein a clarified water solution is obtained; wherein the liquid phase of the solution is economically reclaimed, while the solid phase slurry is disposed of. |
