Investigation on Biofilm Activity in Vermifilter with Filter Media of Different Diameter

A hybrid model for biofilm growth on a deformable substratum

“…Other studies [9][10][11][12][13][14][15][16][17][18] investigated the deformation of the biofilm structure in response to the surrounding flow field but not the mutual interaction between the biofilm and the deformability of the substratum. In particular, biofilms that grow on very thin elastic membranes, [27] such as in the case of filters, as studied by several investigators, [28][29][30] are likely to exhibit a potentially significant coupling between the biochemistry of the biofilm and the compliance of the substratum as suggested by Dalton et al [3] and possibly that of the biofilm itself.
