Abstract:
Anaerobic filter is a major concern in the treatment of landfill-leachate and one
major drawback is the usage of expensive packing media. Hence the investigations
on low-cost and locally available packing media would be a useful research. This
study was focused on assessing the applicability of low-cost and locally available
materials as packing media in two field-scale anaerobic filters connected in series to
treat landfill-leachate. The treatment was processed through the first anaerobic
filter filled with dewatered alum sludge and sea sand, and the second filter
following filled with sawdust and bio char. The concentrations of the organic
compounds, nutrients and heavy metals were measured in the influent and effluent
of die anaerobic filters. The treatment efficiencies of the BOD5 was 27% and
increased with time.COD removal efficiency was 35.2%. There was considerable
treatment efficiencies for ammonia and phosphorus. The removal efficiency of Cu2+
increased with the time from 20 to 100 percentage.
