Effectiveness of Organics and Nitrogen Removal from Municipal Landfill Leachate in Single- and Two- Two- T Stage SBR Systems
E. Klimiuk, Dorota Kulikowska · 2004
The efficiency of organics and nitrogen removal from municipal landfill leachate in activated sludge operated as single and two-stage SBR were investigated. Leachate from mature landfills are characterized by high N/COD ratio (> 0.5). In single activated sludge system at the hydraulic retention time (HRT) 3d and at methanol dosage 8 mg COD/mg N NO3 complete ammonium nitrogen removal was obtained. Ammonium concentration in the effluent was 0.15 mg N NH4 /dm 3 and nitrate
