TREATMENT OF A WASTEWATER FROM VITAMIN C PRODUCTION WITH NANOFILTRATION AND ACTIVATED CARBON
Solid waste originated form vitamin C production was deposited on the municipal landfill at the main landfill of the city of Zagreb where its constituends leached into the wastewater form the landfill. The leachate was treated using a pilot-scale ultrafitration and nanofiltration modules. Also, the removal of the organic load from the leachate using laboratory-scale activated carbon column were performed. Common water contaminants, such as major cations and anions, chemical oxygen demand (COD) and total organic carbon (TOC), were determined using standard methods, while the identification and quantitative determination of pharmaceutical compounds was performed using gas chromatography – mass spectrometry. Ultrafiltration revealed that 90 % of the organic load of the landfill leachate belonged to the fraction smaller than 10 kDa, while the contribution of pharmaceutical compounds to the total organic carbon was 1-5 %. High removal rates were obtained for the organic load (COD and TOC) both using nanofiltration membranes (85-98 %) and activated carbon adsorption (70-85 %), The removal of pharmaceutical compounds (M.W. from 200 to 300 Da), by nanofiltration was fairly efficient (>90 %) while the rejection rates for conductivity and total dissolved solids were lower (<60 %).
