One of the major pollution issues caused by the municipal solid waste landfill is leachate, which creates a huge risks to contaminate groundwater, surface water as well as surrounding land quality. The leachate of Nam Son landfill contains high concentrations of pollutants such as COD, BOD5, NH4 + -N. Hence, this study focused on setting up a bio-filter system and investigating its performance on Nam Son landfill leachate after pre-treatment by electrocoagulation (EC). The characteristics of raw leachate for bio-treatment were as following: pH = 8.7 8.9, COD = 1391 – 1492 mg/L, NH4 + -N = 661 818 mg/L. The experimental system was set up with use volume of 20 lit (dimension: l = 0.15 m, w = 0.28 m and h = 0.52 m) in conditions: room temperature (25-32 o C) flow rate from 2 – 6 L/day, bio-media had a specific surface of 200 m 2 /m 3 . The experimental results were found that COD treatment efficiency from 78–96 % with input COD load from 0.12 – 0.45 kg/m 3 /day. The NH4 + -N treatment efficiency from 98–99.9 % with input NH4 + -N load from 0.08 ÷ 0.25 kg/m 3 /day. The research results indicated that the leachate treatment by combination of electrocoagulation and bio-filter system can promise as a potential method in practice.
