Complex wastewater treatment using membrane separation
Original language description
This paper deals with the application of membrane separation processes for wastewater treatment, especially for landfill leachate treatment. With its high efficiency and low costs, membrane separation seems to be a good choice of other possible progressive techniques. The landfill leachate chosen for this work contained a tremendous number of contaminants. The concentration of dissolved solids was around 10 g.L-1 and the conductivity was 11.3 mS.cm-1. Reverse osmosis was chosen as the most convenient separation technique for this kind of wastewater. Two-stage reverse osmosis showed the best results; nevertheless, one-stage treatment could also be sufficient. A pre-treatment step is necessary in both cases because it determines the separation level, especially the content of ammoniacal nitrogen in permeate. The total efficiency of contaminant removal exceeded 99 % for each contaminant (2 stages). The final amount of the produced concentrate was 20 % of the feed volume. The conductivity
