Abstract
This work, the filtration performance of two types of water filters for the purification of water was investigated. Rice husk was used as a pore former on one hand, while hydrogen was used on the other hand ac a pore inducer. The clay was wet sieved and then mixed thoroughly in three proportions of 15%, 30% and 50% by volume each for rice husk and clay for ceramic water filter production. The other filter made of clay and hydrogen peroxide was achieved by adding 30ml, 45ml, and 60ml each of a 40% concentration of industrial grade hydrogen peroxide into a thick clay slurry mixed with 2600grams of Edda clay for each filter sample. The mixture was then blungged using an electronic blunger. The filter pots were cast in a plaster of Paris (P.O.P) mold. The pots were made to hold 5 litres of water at a time. Both samples were allowed to dry and the fired at 9000C in an electric kiln. The rates of filter for the rice husk filters (RHF) ranged between 0.14litres/hr. to 0.62litres/hr. while that of the Hydrogen peroxide filter (POF) showed a filter rate of between 0.4litres/hr. to 0.87litres/hr. The results obtained from the filter rate characteristics, shows that all the six filters that were used in the experiment was found to be similar to those of Wongsakoonkan, Prechthai and Tantrakarnapa (2014) in the filter rate standards, since they all had their flow rate between 0.4-0.87 liters per hour (L/h). The results showed that, the two kinds of filters did indicate a significant difference in their flow rates, indicating a more even distribution of porosity in (POF) clay-hydrogen peroxide filter. It was observed that this kind of filter could easily be tailored to have a range of porosities when using different compositions of the hydrogen peroxide. This can be useful in the removal heavy metals in water.
