Leachate recirculation: moisture content assessment by means of a geophysical technique.

摘要: Bioreactor technology is a waste treatment concept consisting in speeding up the biodegradation of landfilled by optimizing its moisture content through leachate recirculation. The measurement variations critical design and control bioreactors. Conventional methods such as direct physical sampling reach their limits due to interference with matrix. This paper reviews geophysical measurements electrical current electromagnetic slingram for measuring conductivity. Electrical conductivity property, which linked both temperature can provide useful indications on environment mass. study three site experiments: first experimentation shows advantages (correlation between conductive anomaly water seepage) but also interpretation; two other sites allow recirculation be tracked studying relative resistivity variation versus time from 2D imaging. Even if some improvements are necessary consider real bioreactor monitoring tool, results promising could lead use imaging designing.
