| Abstract | In this study, prediction of filter efficiency was studied using
modified O'Melia-Ali's model. The model used in the present study for the
entire cycle of filtration was developed theoretically assuming an
analogy between the filtration and adsorption. The effect of variation
of filtration rate, particle size of suspension and filter grain size were
studied experimentally using a laboratory-scale filter set-up. Latex
suspension and a glass bead medium of known sizes were used in this study.
The model parameters calculated using the experimental results were found
to follow a uniform trend with the operating parameters. An empirical
relationship between model parameter and operating parameters were
formulated. Once this kind of empirical relationship is formulated from
a limited number of experiments, it can be used to simulate the filter
performance at any other operating parameters of the given system. This
will be useful in the rational design of filter and upgrading the
performance of existing filters as well.
The clean bed filter efficiency calculated from experimental results
were found to be close to Happel's and Rajagopalan-Tien's model. |
