Abstract
This paper deals with the elaboration of porous ceramic pots with raw clay
materials and rice husks for water filtration. The basic raw clays have been
mixed with rice husks at different ratio 10% and 15% weight (wt) and sinter-
ing at 1200˚C, 1300˚C and 1400˚C for 30 minutes. The elaborated pots have
been tested for their densification properties and filtration flow. The mineral-
ogy and microstructure of pot have been also studied to explain the different
results. The pot with 10% wt rice husks and sintering at 1300˚C during 30
minutes presents a sufficient porosity and mechanical strength to be used for
water filtration.

1. Introduction
The analysis of water sector in Burkina Faso shows that 11% of urban population
and 33% of rural population have no access to drinking water [1]. The principal
reasons are the pollution of great part of surface and underground water. The
pollutants are principally chemical (sulfate, nitrate, metals), physical (alteration
of limpidity), microbiological and organic. Their origins are natural and anth-
ropic. Chemical pollutants are generally present in the rock in salt form and
dissolve in the running water at concentration higher than the standards of
World Health Organization. The mining boom in our country is another reason
of water pollution. The water resources of mining areas are polluted with cya-
nide and metals like arsenic, mercury. In addition, with population growth, the
