Theoretical modeling of flow for frustum-shaped ceramic water filtersvia disc-shaped ceramic water filters

In the past two decades, research on household technologies has been on the increase. Ceramic water filters are simple and appropriate technology proven to have capability to provide improved drinking water especially in rural and peri-urban communities. These filters can be fabricated into various shapes with careful consideration of their mechanical robustness. This paper gives an overview of various flow models in estimating flow rate for ceramic water filters, in particular frustum-shaped ceramic water filters. Analytical approach to estimate the quantity of water considering the geometrical shapes; frustum and cylindrical shapes of the Ceramic water filters are adopted. The analytical expressions deduced for the flows are applicable on the assumption that the materials used in the fabrication of the filters are the same, thus same material properties (chemical and thermal properties) and porosimetry characteristics. Also, the comparative flow equation is largely dependent on dimensions of the ceramic water filters. The scholarly articles on flow through ceramic water filters for frustum-shaped filter are theoretically explored.
