The use of cheap, locally available peat as a treatment method for landfill leachate was investigated by passing leachate through plexiglass columns filled with an amorphous-granular peat. Preliminary adjustment of pH showed that reducing pH to 4.8 dramatically reduced adsorption. Increasing the pH to 8.4, metal removal was increased owing to filtration of precipitated metals. The best adsorption of metals occurred at the 'natural' pH of 7.1. Manganese was found to be the limiting pollutant. At the 0.05 mg/ℓ maximum acceptable manganese concentration 94% of the total metals were removed, requiring 159 kg of peat per 1000 ℓ of leachate.Resting the peat for 1 month did significantly increase removal capacity.Desorption of some contaminants occurred when water was percolated through the peat. The desorption test effluent was not toxic to fish although iron, lead and COD (chemical oxygen demand) exceeded acceptable values.Chemical pretreatment using lime and ferric chloride achieved significant iron, manganese and calcium removals. Chemical pretreatment followed by peat adsorption offered no advantage other than reducing toxicity to fish.Peat treatment alone was effective in reducing concentrations to a level that was non-toxic to fish.

Overpopulation and industrialization are the major sources of wastewater in human society and water resources. Food production industries and municipal solid waste are the root origin of wastewaters containing palm oil mill effluent and municipal landfill leachate. Traditional treatment method for such highly polluted wastewaters cannot meet environmental discharge. Finding an advanced and smart decontamination process for these types of polluted wastewater could be considered as a capable method for suitable adaptation with overpopulation in current condition and future coming decades. This chapter illustrates critical points through the application of traditional treatment techniques such as acclimatization in palm oil mill effluent and municipal landfill leachate as the most straightly polluted agro-industrial effluent.
