“…Based on the results obtained from this research, higher BOD 5 /COD ratios were obtained mainly due to the higher COD (5,096 ± 92 mg/L to 751 ± 52 mg/L) removal in comparison with BOD 5 (238 ± 51 mg/L to 201 ± 11 mg/L) that enhances the biodegradability of the leachate. The biodegradability evaluation (an improvement from stabilized to intermediate phase) from this current study is quite identical to the work reported by Bashir et al (2019) in the treatment of palm oil wastewater using a mixed process of electrocoagulation‐peroxidation which revealed an increment in BOD 5 /COD ratio from 0.037 (85 mg/L to 2,586 mg/L) to 0.14. Another study by Fernandes et al (2014) which uses a combined treatment of electrocoagulation‐anodic oxidation process to treat landfill leachate also demonstrated big improvement in BOD 5 /COD ratio from 0.33 (7.0 mg/L to 22.2 mg/L) to 0.88.…”

The high-strength leachate produced from sanitary landfill is a serious issue around the world as it poses adverse effects on aquatic life and human health. Physio-chemical technology is one of the promising options as the leachate normally presents in stabilized form and not fully amendable by biological treatment. In this research, the effectiveness of natural zeolite (clinoptilolite) augmented electrocoagulation process (hybrid system) for removing high-strength ammonia (3,442 mg/L) and color (8,427 Pt-Co) from naturally saline (15 ppt) local landfill leachate was investigated. A batch mode laboratory-scale reactor with parallel-monopolar aluminum electrodes attached to a direct current (DC) electric power was used as an electrocoagulation reactor for performance enhancement purpose. Optimum operational conditions of 146 g/L zeolite dosage, 600 A/m 2 current density, 60 min treatment time, 200 rpm stirring speed, 35 min settling duration, and pH 9 were recorded with up to 70% and 88% removals of ammonia and color, respectively. The estimated overall operational cost was 26.22 $/m 3. The biodegradability of the leachate had improved from 0.05 to 0.27 in all post-treatment processes. The findings revealed the ability of the hybrid process as a viable option in eliminating concentrated ammonia and color in natural saline landfill leachate. © 2020 Water Environment Federation • Practitioner points • Clinoptilolite was augmented on the electrocoagulation process in saline and stabilized landfill leachate (15 ppt). • The high strength NH 3-N (3,442 mg/L) and color (8,427 Pt-Co) were 70% and 88% removed, respectively. • The optimum conditions occurred at 140 g/L zeolite, 60 mA/cm 2 current density, 60 min, and final pH of 8.20. • The biodegradability of the leachate improved from 0.05 to 0.27 after the treatment. • This hybrid treatment was simple, faster, and did not require auxiliary electrolyte.

“…Devlin et al (2019) studied effect of electrode materials, that is, aluminum, iron, ANNUAL LITERATURE REVIEW and magnesium, on electrocoagulation treatment of municipal wastewater.Results showed that aluminum and iron electrode exhibited 8-9 times higher reaction rate than magnesium electrode for orthophosphate removal. Bashir, Lim, Amr, Wong, and Sim (2019) investigaed the post treatment of palm oil mill effluent by combination of electrocoagulation and peroxidation. The result showed that 71.3%, 96.8%, and 100% removal of COD, TSS, and color, respectively at current density of 40.21 mA/cm 2 , 0.5 g/L of H 2 O 2 dosage, and 45.67 min reaction time at the initial pH of 4.4.…”

“…The selection of the optimum treatment technology depends upon the characteristics of landfill leachate and its composition [14]. Landfill leachate treatment generally involves multistage or integrated technologies for better removal efficiency, as any single technology cannot obtain desired results for the effluent of LFL to be discharged into water bodies [15].…”

Strategies of Sustainable Solid Waste Management

Improper Solid Waste Management leads to the generation of landfill leachate at the landfills. To reduce the negative impacts of highly toxic and recalcitrant leachate on the environment, several techniques have been used. A lot of research is conducted to find suitable methods for the treatment of landfill leachate such as biological processes, chemical oxidation processes, coagulation, flocculation, chemical precipitation, and membrane procedures. The biological process is still being used widely for the treatment of leachate. The current system of leachate treatment consists of various unit processes which require larger area, energy and cost. In addition, the current aerobic treatment is not able to treat entirely the pollutants which require further treatment of the leachate. Anaerobic wastewater treatment has gained considerable attention among researchers and sanitary engineers primarily due to its economic advantages over conventional aerobic methods. The major advantages of anaerobic wastewater treatment in comparison to aerobic methods are: (a) the lack of aeration, which decreases costs and energy requirements; and (b) simple maintenance and control, which eliminates the need for skilled operators and manufacturers. Several anaerobic processes have been used for leachate treatment such as up-flow anaerobic sludge blanket (UASB) reactor, anaerobic filter, hybrid bed reactor, anaerobic sequencing batch reactor and Anaerobic baffled reactor. The following chapter provides an insight to the solid waste management at the landfills, generation of leachate and details of some of the highly efficient anaerobic treatment systems that are used for the overall treatment of landfill leachate.
