Treatment of a Landfill Leachate Containing Compounds of Pharmaceutical Origin

Paper reports the results of landfill leachate treatment with membrane bioreactor, nanofiltration and ozonation. Investigated leachate encompasses a number of specific compounds of pharmaceutical origin, including a suite of by-products deriving from the production of vitamin C and propyphenazone. Low biodegradability was observed in MBR (16 %) for propyphenazone, while the removal of intermediates from the vitamin C-synthesis was moderate, reaching 30 % for diacetone sorbose (DAS) and 69 % for diacetone alpha-keto-gulonic acid (DAG). Ozonation almost completely removed propyphenazone but failed to significantly oxidise intermediates from the vitamin C-synthesis. Nanofiltration of the leachate succeeded to remove 99 % of DAG and 79% of propyphenazone which made it the most efficient among techniques used.
