Landfill leachate treatment using membrane separation: summary of laboratory testing experiences

Original language description

This study deals with the problem of landfill leachate treatment using membrane separation processes Large experience was performed in this field using samples of various landfill leachates from landfills for municipal and hazardous waste disposal. Screening of the samples composition in the Czech Republic showed their large variability. Large spectrum of inorganic components was analysed and the following maximal concentrations were measured: Na 2124 mg.L-1 , K 1912 mg.L-1, ammonia nitrogen 3178 mg.L-1, chlorides 3108 mg.L-1, nitrates 491 mg.L-1, sulphates 1300 mg.L-1, carbonates 9870 mg.L-1and TOC 1554 mg.L-1. The conductivity values of leachates were between 6.1 – 22 mS.cm-1 and pH values between 7.5 – 8.7. A set of membrane separation experiments using different operating conditions was performed on every landfill leachate with complete analyses of all streams. The combination of reverse osmosis and pretreatment reduced the volume of landfill leachate by approximately 80 % using one separation stage; the next stage improves the composition of permeate. The number of treatment stages may be ruled by local legislation. Reverse osmosis showed high separation efficiency (over 95 % in most cases) regardless of the feed quality for all pollutants and the decrease in conductivity was also considerable. The designed and verified treatment schema allows optimization of the treatment process with regard to the output streams disposal.
