“…During stabilization of leachate, anaerobic treatment is carried out by anaerobic microorganism which can degrade organics to carbon dioxide and methane. This result is in line with the results Kamaruddin et al (2013). The study monitored the effect of leachate stabilization on organic and ammonia removal and reported 76% and 52% removal for COD and ammonia, respectively, during leachate stabilization.…”

In this study, leachate collection and processing system in Ampar Tenang Closed Landfill (ATCL) and its impact on both groundwater and surface water was evaluated. Samples from three locations in leachate processing system (Collection, aeration and stabilization ponds), groundwater and surface water were collected and tested for twenty-one parameters covering nine heavy metals (Fe Correlation analysis for landfill leachate ponds, groundwater and surface water showed different patterns of relationships between all possible combinations of two parameters. Similarity and dissimilarity were studied through cluster analysis, three clusters were found to entirely separate the collection pond (cluster 1) while the two ponds were clustered with groundwater samples (cluster 2) and the third cluster is for the surface water. This study shows the benefit of statistical analysis such as correlation analysis and cluster analysis for evaluation and interpretation of landfill data to understand the behavior of the selected parameters and to have a clear picture about the pattern of the relationship for effective landfill management. ABSTRAKDalam kajian ini, sistem pengumpulan dan pemprosesan air larut resap di Tapak Pelupusan Tertutup Ampar Tenang (ATCL) dan kesannya terhadap air bawah tanah dan air permukaan telah dinilai. Sampel daripada tiga lokasi dalam sistem pemprosesan air larut resap (kolam pengumpulan, pengudaraan dan penstabilan), air bawah tanah dan air permukaan diperoleh dan diuji untuk dua puluh satu parameter iaitu sembilan jenis logam berat (Fe dan oksigen terlarut (DO)). Analisis korelasi untuk kolam air larut resap, air bawah tanah dan air permukaan menunjukkan corak hubungan yang berbeza antara semua kemungkinan gabungan dua parameter. Persamaan dan ketidaksetaraan dikaji melalui analisis kelompok dan tiga kelompok didapati memisahkan kolam pungutan sepenuhnya (kelompok 1) manakala dua kolam berkumpul dengan sampel air bawah tanah (kelompok 2) dan kelompokketiga adalah untuk air permukaan. Analisis statistik seperti analisis korelasi dan analisis kelompok untuk penilaian dan pentafsiran data tapak pelupusan sampah dapat membantu dalam memahami ciri-ciri parameter terpilih dan untuk mendapatkan gambaran yang jelas mengenai corak perhubungan bagi pengurusan tapak pelupusan sampah yang berkesan.Kata kunci: Air larut resap; analisis kelompok; logam berat; matriks korelasi; statistik diskriptif; tapak pelupusan sampah

“…Normally, the concentration of heavy metals in leachate at the early stage of landfill operation are high due to higher metal solubility and dissociation of organic acids (Kulikowska and Klimiuk 2008). The colour concentration was reported as 1586 mg/L which is due to the low biodegradability of dissolved organic constituents in the leachate (Kamaruddin et al 2013 [ (PO 4 ) 3 . However, the value of correlation coefficient, R, 2 displayed an inversely trend, which showed that adsorption of ammonia nitrogen (NH 3 -N), colour and chemical oxygen demand (COD) on Indion MB 6 SR resin were not adopted in Langmuir isotherm model.…”

Semi-aerobic stabilized landfill leachate treatment by ion exchange resin: isotherm and kinetic study

This study was carried out to investigate the treatability of ion exchange resin (Indion MB 6 SR) for the removal of chromium (VI), aluminium (III), zinc (II), copper (II), iron (II), and phosphate (PO 4 ) 3-, chemical oxygen demand (COD), ammonia nitrogen (NH 3 -N) and colour from semi-aerobic stabilized leachate by batch test. A range of ion exchange resin dosage was tested towards the removal efficiency of leachate parameters. It was observed that equilibrium data were best represented by the Langmuir model for metal ions and Freundlich was ideally fit for COD, NH 3 -N and colour. Intra particle diffusion model, pseudo first-order and pseudo second-order isotherm models were found ideally fit with correlation of the experimental data. The findings revealed that the models could describe the ion exchange kinetic behaviour efficiently, which further suggests comprehensive outlook for the future research in this field.

“…Meanwhile, significant reduction of TSS, COD, BOD 5 , NH 3 -N, and TP of 98, 92, 79, 54 and 99 % was recorded, respectively. In another work, using anaerobic organisms in a series of anaerobic tanks filled with leachate, 100 mL of anaerobic organism and 14 days of microbial inhibitors, 65.5, 60.2 and 46.3 % of COD, NH 3 -N and color were removed, respectively (Kamaruddin et al 2013). …”
