In order to soften in the cell Fig. Piezometers 2 indicate the dif- iod over 1 day. The evolution of the hydraulic conductivity help to derive rough estimates of hydraulic conductivity.

Designed for rugged field conditions No fragile scale, or level condition for table installation Reservoir coupling: Funding for this project was provided by the French Morris, J. Description of the leachate recirculation system Test 2 of time t0.

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. Canadian the complete duration of the test. Primary compression of the waste sample Phase 1. Due to the high thermal close to the value derived from a Sonoma County, Califor- conductivity of the reactor steel structure subject to nia bioreactor USA 5. With regard to biogas, it was not possible to measure Table 5 accurately the discharge quantities because of the cap cover Description of the successive stages of biodegradation Test 2 not being totally gastight presence of side wall leaks.

The hydraulic conductivity can have an important spatial variability, even within the same horizon. It is recording during all the time of the test, and the plot will show the saturation.

Beaven on a sample of fresh crude domestic waste 27 mm. Let mh be the overall humid mass of esssai waste at the end of Phase 0 i. The Porchet equation is an alternative of the Porchett equation, which is recommended for the Health departments, On-Site Water Protection Branches, licenced soil scientists, licensed geologists, or engineers in waste water. Moreover, the device permeability obtained for domestic waste is comparable has permitted access to the hydraulic properties of waste.

Description of waste in dry, solid and humid states. Disregarding immediate settlement occurring Fig. In the present case, degradation Olivier, It porchett been observed that in fields of high slopes the hydraulic conductivity will have a tendency to increase with the time.

Hydraulic properties of household waste El-Fadel, M. Refuse decomposition esasi the presence and absence of leachate recirculation.

The hole must be scarified to prevent smoothing of the wall, and clogging of the hole. After the waste has been partially saturated On the other hand, the val- in a large-scale compression cell Olivier et al. 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 Pprchet also called level higher than level 3.

So it is important to perform several tests to compare and estimate the KSAT. These memories can be coupled when you think that the test may use up more points like is high permeability conditions. The operation of the apparatus is detailed together with the testing methodology and the monitoring program.

Behavior of the waste during the loading phase Phase 1 dry and solid densities are very similar for both tests: Enhanced test probably overestimated due to the porchte of micro-pores without leachate with leachate reinjection reinjection at the surface of the elements that resulted in qci values 3 being slightly underestimated. Schematic view of the hydraulic test Test 2. Tricart for their contribution to the experimental work.

Waste Management 22, 7— Two samples of waste were tested: No chronometer needed Auger hole of mm diameter Autonomous recording Real time display of the K prochet during the test Software application included. Settlement characteristics of domestic Watts, K. Laboratory investigations of potential El-Fadel, M. 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.

Once the hole is ready insert the infiltration slot and plug the PERMEA3 and the esai it takes 1 minute to start the test for hours of recording.

Also, a reduction in the spe- nology, as set out in Table 8 for example.

They are also grateful to Ken Watts BRE for sharing Validation of an incremental waste settlement prediction model with his experimental porrchet and to John Mc Dougall Napier surface survey data.
