Biological Treatment Kinetics of Landfill Leachate

Abstract: Biological treatment study with sanitary landfill leachate was conducted using a laboratory scale, continuous flow, activated sludge unit The treatment kinetic coefficients have been developed and are in this paper Simulated landfills were constructed and operated to produce leachate for treatment study The leachate was diluted and was used as substrate in the continuous flow biological reactor The bench-scale reactor was designed to simulate a continuous flow, complete mix, activated sludge model with sludge recycle and was operated at different concentrations of mixed liquor suspended solids Growth kinetic coefficients Y, k d , and substrate removal kinetic coefficients k, K s were determined from the test data and were compared with those for domestic sewage The overall performance of the experimental unit and the results indicate that the landfill leachate can be effectively treated in a conventional activated sludge plant

Method of testing a landfill for its methane potential

Abstract: Method of testing a landfill for its methane potential comprising selecting a landfill which contains a significant decomposable fraction and a significant non-decomposable fraction, locating a plurality of zones within the landfill with each of said zones having at least one different characteristic, taking at least one sample of the material of the landfill at each of the zones, measuring the content of each of the fractions of each of the samples, and utilizing the ratio of one of the fraction contents to the other of the fraction contents for at least some of the samples to find the approximate methane potential of the landfill.
