Abstract

This paper focuses on the study of high ammonium concentrated wastewater with SBR reactors. Four type of wastewaters, landfill leachates (T=20 degrees C) and the reject water (T=35 degrees C) coming from mesophilic anaerobic digesters of sewage sludge, pig slurry and organic fraction of municipal solid waste (OFMSW), were studied in four SBR during 6 months. The removal of nitrogen was done in all the cases with nitrification/denitrification via nitrite obtaining high removal nitrogen conversions for the three types of reject water (0.75-0.85 kg N day(-1) m(-3)) and lower for landfill leachates due to temperature requirements (0.3 kg N day(-1) m(-3)).
