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.

Location and depths of the auger holes must be carefully selected to represent the proposed, or suggested, dispersal volume and area. Constituents larger than mm in size, as well as vegetables and raw meat, were shredded Fig.

Still, it was visually observed at the end of the test that Although a comparative study may have been instructive dry grass, vegetables and fruits, rice and raw meat had from the point of view of waste physical characterization, almost completely disappeared whereas paper, newspaper no reference tests were carried out at the start of the com- and leaves appeared little degraded Fig.


Evolution of the hydraulic conductivity of the waste with time Test 2.

Control test Test 2: 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. Piezometers 2 indicate the dif- iod over 1 day.

A pedological log and correlated interpretation need to be assessed in order to understand the values of the hydraulic conductivity. Comparisons are fssai considering the results derived from the few monitoring programs conducted on experimental bioreactors worldwide.

The technician can follow the evolution and react if the values seem incorrect.

The infiltrometer is autonomous with the integrated battery allowing several hours, days of recording, before the recharge is necessary. In addition, the presence of plastic foils volume of material.

The variability in the soil types, the landscape morphology, and the position of the considered project have to be taken into account to position the tests on the drainfield, and determine the numbers of tests.

Composition and placement of the waste Tests 1 and 2 The waste was constituted on the basis of compositions suggested earlier by Lanini and Thomas for household waste, i.
