“…With neutron probe, water content can be measured regardless of its physical state but the results are affected by changes in density. Furthermore, the radioactive source of neutron probe is a highly regulated material, and automation is not possible (Yuen et al, 2000). With electrical resistance sensors, automated measurement is possible, and readings are not affected by density.…”

Water content measurement of municipal solid waste (MSW) is critical to water balance analysis of landfill, leachate collection and recirculation, and acceleration of MSW degradation. Time domain reflectometry (TDR) is commonly applied to soils for the measurement of water content. Application of TDR methods for moisture measurement in MSW is difficult, because MSW is a heterogeneous and highly conductive material. This study investigated the application of TDR surface reflection method for the determination of apparent dielectric constant and water content of MSW. A series of experiments were conducted to study the dielectric properties of MSW and its main components such as paper, plastic, and organics. Results indicate that the effect of waste material type seems to be negligible on the measurement of water content. TDR technique can effectively measure the intrinsic water of organics in the absence of significant bound water effects. Results of dielectric constant by surface reflection method gave similar accuracy as the conventional travel time analysis for waste materials with low electrical conductivities. In addition, surface reflection method provides higher accuracy for waste materials with high electrical conductivities than travel time analysis. This research provides experimental basis for the use of TDR surface reflection method in landfills.

“…Two publications proposed an extensive review of different moisture measurement techniques for MSW within landfills [15,16]. Ideally, moisture measurement techniques should include characteristics such as reliability, ease of measurement, non-destructiveness, repeatability, accuracy and large sampling volume [10]. Most of the techniques are sensitive to several parameters and require accurate calibration.…”

“…A continuous monitoring of MSW moisture seems essential to operate the landfill and this is only possible when real-time and non-destructive moisture content measurements are made. MSW moisture measurements are also needed to better predict the remaining biodegradation potential of existing landfills and for the study of multiphase flows [10] or landfill settlements [11].…”

Abstract.A new method based on PGNAA technique has been proposed for moisture content and elements concentration determination in landfills. Due to the complexity of MSW component, the compounds of polyethylene balls, glass balls and water were selected as the MSW alternatives for research. By changing the proportion of polyethylene and glass ball, water contents of five samples were regulated to 40.522%, 47.575%, 55.168%, 63.369%, 72.251%, respectively. Based on a new set-up was developed to validate the method by MCNP simulations and experimental researches. The results show that the counts of hydrogen peak increase with the increase of the moisture content for samples, and good linearity can be figured out between the counts of hydrogen peak.
