Better Than

Municipal leachate was treated in an experimental unit of constructed wetlands of subsurface flow type. The parameters studied were organics (BOD and COD), solids and heavy metals (Zn, Ni, Cu, Cr and Pb). Using two types of emergent plants of Scirpus globulosus and Eriocaulon sexangulare, more than 80% removal was achieved for all the parameters. E. sexangulare removed organics and heavy metals better than Scirpus globulosus. A higher concentration of heavy metals in the influent did not change the removal efficiency.

Minimum Criteria

Recently in the USA, the Solid Waste Industry has undergone specific changes in landfill regulations. The Federal Resource Conservation and Recovery Acts (RCRA); and EPA subtitle D regulations, as well as stringent State regulations, impose minimum criteria for municipal solid waste facilities in the areas of location, operation, groundwater monitoring, and leachate management. In conjunction with these State and Federal mandates the University of West Florida developed a leachate treatment technique utilizing extended aeration and surface-flow constructed wetlands. Sampling of water quality has occurred monthly since February 1992. Parameters examined include: Nitrogen (NH3,), Total Suspended Solids (TSS), Total Phosphate (TPO4), Total Organic Carbon (TOC), pH, Alkalinity, and Chlorides. Chemical Oxygen Demand (COD), Total and Fecal Coliforms, Priority Pollutant Metals, and limited organic analytes are sampled on a less frequent basis. Samples are collected at a raw leachate site (L0), primary aerated lagoon (L1), and 6 stations within the 1.1 hectare constructed wetland complex (S1; W1; W3; W5; W7; W9) and one sandfilter (SF) location. Results thus far indicate removal percentages of the tested analytes average between 64% and 99%. This data suggests various physical, microbiological and chemical processes occurring within the aerated lagoon and constructed wetlands can provide an effective alternative to standard techniques for landfill leachate treatment and disposal. The methods as described have proven to be ideal for the circumstances occurring at the Perdido Landfill.

Landfilling is one of the most important methods for disposal of solid waste in many countries. One of the most obvious problems associated with the landfilling practice is the generation of leachate. This chapter reviews case studies on the on-site treatment of leachates using various technologies in selected European and Asian countries. It was shown that the generation of leachate varies widely in both quantity and quality in European and Asian countries. Biological treatment and membrane technology show very high efficiencies in treating leachate generated from Odayeri landfill (in European side of Turkey) and Komurcuoda landfill (at Asian side of Turkey). Leachates from Arpley landfill (UK) and Bukit Tagar landfill (Malaysia) were successfully treated using sequence batch reactor (SBR). Fairly good treatment efficiencies were obtained using constructed wetlands (CWs) in treating Gdansk-Szadolki landfill leachate in Poland. Furthermore, the use of coagulation, filtration and membrane technologies has been proven effectively in treating Nonthaburi landfill leachate in Thailand.

This chapter deals exhaustively with the various techniques employed in polishing landfill leachate, the role, importance and effects of polishing leachate and the use of constructed wetlands with many examples from some countries where it has worked with considerable success. Types, forms and functions of wetlands in leachate polishing were also dealt with while the chapter also provides information on the advanced treatment wetlands technology being employed now for polishing landfill leachate; its design considerations and future projections. The role of bioremediation and aquatic plants in leachate treatment was also considered and reviewed while projected futuristic outlook of polished landfill leachate was examined.
