... . This concentration is significantly higher than typical septic tank effluent concentrations, but was chosen to increase the rate of bioclogging. Each column was loaded as shown in Table 2 , and the 2-L pulse was simply poured onto the top of the columns. As the columns clogged and ponding occurred, the number...

...Yuxin Wu; Vikranth Kumar Surasani; Li Li; Susan Sharpless Hubbard ABSTRACT Although bioclogging has been used for various applications, its performance has been unpredictable. We carried out a bioclogging experiment and developed a reactive transport model to understand and quantify geophysical...

...; however, efforts to develop similar models for unsaturated soils have been limited. Recently, Mostafa and Van Geel proposed three conceptual models to simulate bioclogging in unsaturated systems. These models included the impact of biomass growth on the relative permeability term for unsaturated flow...

... of the matrix that are adjacent to fissures. One possible mechanism of this ‘bioclogging’ is the formation of gas bubbles, which in other contexts have been shown to be extremely effective at blocking pores (e.g. Baveye et al. 1998; Beckwith & Baird 2001). The experiments carried out by Soares et al...

... because of the reduction of charge passages due to bioclogging. However, the imaginary conductivity significantly increases with time, and clear bell-shaped relaxation behaviors are observed with the peak frequency of 0.1–1 Hz, associated with the double-layer polarization of cells and electrically...

... and bioclogging were responsible for the reduction in measured hydraulic conductivities of soil-leachate samples. These effects can be clearly observed from the field-emission scanning electron microscopy images of soil-leachate samples with the appearance of less visible voids that led to a more compact...
