The availability of pure, clean and safe usable water for drinking and
other domestic use is a major challenge faced by most developing
nations' rural communities. In the pursuit to make available safe, pure
and clean usable water, a ceramic clay filter produced from clay soil
is used as an absorbent barrier in household water treatment.
To investigate the effectiveness of rate of flow through ceramic clay
filters when treated with up to 20 % rice husk, five different ceramics
filters were produced at 0 %, 5 %, 10 %, 15 %, and 20 % addition of
rice husk in the laboratory and were sintered at 1000O C. Water flow
rate were measured for the ceramic clay filters produced by
measuring the volume of filtrate. It was found that the volume of
filtrate increased as the percentage of rice husk added to the clay soil
increased.
