Composition and method for pretreating landfill leachate on mechanical vapor recompression evaporation process |
| abstract |
A composition for pretreating landfill leachate on mechanical vapor recompression (MVR) evaporation process by which Mg, Ca and ammonia are efficiently removed is provided. The composition comprises 0.2–2 weight-% of cationic polymer, 5–80 weight-% of sodium and/or potassium phosphate, 5–40 weight-% of saccharide, and 5–40 weight-% of sodium and/or potassium carbonate, calculated from the total weight of the constituents in the composition, as dry. A method for pretreating landfill leachate on MVR evaporation process is provided. The composition is added to the landfill leachate prior to conveying the landfill leachate to the evaporation system. |
