This paper presents a study on filtration of water through nanostructures present in calcined carbonated calcium phosphate bioceramic powder derived from fish bones in terms of improving the clarity of water. In this study, fish bones were extracted, dried, calcined for 2 hours at a constant 900°C and then powdered. The powder was then tested using samples from the Baong River in Miri for turbidity and total suspended solids (TSS) tests, as well as particle retention of a premixed sample of starch suspension. The results indicate that the filter can effectively remove starch molecules from 0.05 mol dm-3 starch suspension. This study also indicated that the filter had been effective in reducing the turbidity and TSS levels from 4.00NTU to 0.90NTU and 110mg/L to 102mg/L respectively. This study concludes that the nanostructures present in the hydroxylapatite powder can effectively improve the clarity of water sampled and it has a significant potential to be used with other filtration materials to remove impurities in water to safe values effectively and cost efficiently.
