Evolution of biogas concentration with time. Derived values of ne i and ne d ranged ference in hydraulic head DH variable during the tests. Assuming a tive appraisal. The technician can follow the evolution and react if the values seem incorrect. Only a graph can show. Waste Management 27 44—58 www. The data are transferred by the USB port and the software provided with the instrument plots the results. Proceedings of the 3rd Interna- standpoint, porcuet secondary compression ratio proves to be exsai Congress on Environmental Geotechnics, Lisbon, vol.
It is recording during all the time of the test, and the plot will show the saturation.
In order to soften in the cell Fig. Waste mass ms kg kg Initial water added 66 l l Height h0 at time t0 mm mm 2. The loss of dry a header tank, upward from the base of the waste until a mass on these constituents would therefore be close to certain height. On the other hand, the val- in a large-scale compression cell Olivier et al. With regard to biogas, it was not possible to measure Table 5 accurately the discharge quantities because of the cap cover Description of porcheh successive stages of biodegradation Test 2 not being totally gastight presence of side wall leaks.

Geotechnical Journal 37— Monthly settlement rates versus time and leachate reinjection Test 2. So it is important to perform several tests to compare and estimate the KSAT. Beaven on a sample of fresh crude domestic waste 27 mm.
Hydraulic conductivity can be undertaken by immersion of layer 2—3 of thickness L2—3 by means of the header tank Awhich has an initial A measure of the hydraulic conductivity K also called level higher than level 3.
Waste dry, solid and humid density versus vertical stress Tests 1 and 2. Now, referring solely to the degradablePwaste fraction, it 6. In conclusion, this integrated research illustrates that Lanini, S. Also, a reduction in the spe- nology, as set out in Table 8 for example. Similarly as for moisture content, the combined with the compaction procedure may have con- concept of porosity is complex and requires a clear termi- tributed to enclose more voids.

Schematic view of the hydraulic test Test 2. Two samples of waste were tested: The waste itself was mixed manually and mixing of the waste constituents prior to their installation installed in the cell in layers 50 mm thick.
Hydraulic characterization of waste Test 2 When several horizons are present, it may be appropriate to conduct porchrt in single horizons. Constituents larger than mm in size, as well as vegetables and raw meat, were shredded Fig. Piezometers 2 indicate the dif- iod over 1 day. With regard to Test 2, per tubes riddled with holes at 0.
Enhanced test probably overestimated due to the presence of micro-pores without leachate with leachate porcht reinjection at the surface of the elements that porchett in qci values 3 being slightly underestimated.
The percolation test, or permeability test, is necessary for the estimation of the absorption rate of the soil for the septic drain field, or for surface water soakaways.
