“…Higher pH values of 8.3-9.10 were recorded from the stabilized leachate of semi-aerobic landfill . However, a lower range of pH values between 6.8-7.5 was previously reported (Jokela et al, 2002). The pH varied according to the age of landfills (Kulikowska et al, 2008).…”

The general characteristics of Kuala Sepetang Landfill Site (KSLS) and Kulim Landfill Site (KLS) in the northern part of Malaysia were investigated. The average values of the parameters for leachate at KSLS and KLS, such as pH (8.05 and 7.59), EC (11.9 and 2.92 mS/cm), ORP (-33.02 and +17.8 On the other hand, parameters such as pH, copper, iron, manganese, nickel, and zinc remained within the allowable limits. The measured leachate would need an appropriate treatment strategy to reduce the pollutants to a satisfactory level prior to discharge into receiving system.

“…It has been proved that the sequencing batch reactor (SBR) is a reliable method for treating landfill leachates [8,9] . It is well known that biological techniques treating landfill leachates are successful in the removal of BOD [7][8][9] and ammonia [10][11][12] . However, COD removal is considerably more challenging, because of removal efficiency varying from 20% to more than 90% depending on characteristics of leachate, types and operational facets of process [11,13,14] .…”

Continuous upflow anaerobic sludge blanket reactor performs more favorably at the higher organic loading rate than other anaerobic treatment. The treatment of municipal landfill leachate of Shiraz's city investigated using continuous flow anaerobic reactor and subsequently aerated lagoon. Landfill leachate has chemical oxygen demand of 45,000-90,000 mg/L and ammonia nitrogen at 1,000-2,500 and heavy metals that can impact biological treatments. Capacity of anaerobic and aerobic reactors is 10 and 20 L that operated at detention time of 2 and 4 days, respectively. Organic loading rate of upflow anaerobic sludge blanket is between 0.5-20 g chemical oxygen demand/L/day. Chemical oxygen demand removal efficiencies are between 57-87, 35-70 and 66-94% in the anaerobic, aerobic and whole system, respectively. As the entry, leachate organic loading rate increased from 1 to 20 g/L/day, the chemical oxygen demand removal efficiency reached a maximum of 71% and 84% in the anaerobic reactor and whole system, respectively, at high organic loading rate. Ammonium removal efficiency was about 54% after the aerobic stage.
