Characterization of soluble organic matter in leachate

Landfill leachate treatment by MBR: Performance and molecular weight distribution of organic contaminant

“…The GPC profiles of leachate represented a bimodal distribution characterized by either DOC or UV254 (Fig. 4(a)), which was similar to the results of Chain and DeWalle [29] and Harmsen [30] . These landfill leachates can be divided into three molecular weight fractions by GPC as follows: 1) Fraction A, V e =100-250 mL, MW >5754 Da, MWp = 11480-13182 Da; 2) Fraction B, V e = 260-340 mL, MW = 1445-5754 Da; and 3) Fraction C, V e = 350-700 mL, MW<1445 Da, MWp = 158-275 Da (Fig.…”

Landfill leachate treatment with a novel process: Anaerobic ammonium oxidation (Anammox) combined with soil infiltration system

“…Therefore, it could be inferred that removed organics in the AR should mainly be fulvic-like material. Because fulvic-like material is aquatic humic substance (AHS) [32], it can be determined by means of the analysis of AHS. Because the analysis of AHS was timeconsuming, only six sets of samples were analyzed.…”

BOD:COD Ratio as an Indicator for Pollutants Leaching from Landfill

“…Both BOD and COD are commonly used to measure organic matter content in leachate with some reporting BOD and COD values of 20 to 57,000 mg/L and 140 to 15200 mg/L respectively [5]- [8]. It is anticipated that BOD and COD value decrease over time most likely attribute to a combination of reduction of organic pollutants that are leaching in the landfill.…”
