Primary treatment of anaerobic landfill leachate using activated carbon and limestone - Batch and column studies
Leachate generated from an old landfill in Taiping, Perak, Malaysia contains high colour, COD, iron and ammoniacal nitrogen. Activated carbon–limestone mixture was used as a primary treatment process. More than 86% of colour and COD, 95% of iron, and 48% of ammoniacal nitrogen were removed by a mixt...

| description | Leachate generated from an old landfill in Taiping, Perak, Malaysia contains high colour, COD, iron and ammoniacal nitrogen. Activated carbon–limestone mixture was used as a primary treatment process. More than 86% of colour and COD, 95% of iron, and 48% of ammoniacal nitrogen were removed by a mixture of activated carbon and limestone (15:25 by volume) in the batch study compared with 70, 80 and 90% respectively, by column study on the first five days. Both Langmuir and Freundlich isotherms had fitted well with the experimental data. The adsorption kinetics followed the
pseudo-second-order model indicating that chemisorption or ion exchange was the rate-controlling step in the adsorption. |
