ABSTRACT
Two Nigerian clays were studied using Atomic Absorption Spectrophotometer and X-ray diffractometer. They were coded OT and BB obtained from Delta State, Nigeria. Mineralogical analysis revealed the presence of kaolinite in the two clays. Illite and Quartz in OT, smectite illite, mixed layer and Quartz in BB. Pebble:Clay ratio of 1:2 was adopted and percolation rate studies showed that BB had lower rate than OT. One and three flow through methods were adopted. This was used in treating effluent from the wood factory. 3 flow through gave outstanding performance on the pollution characteristic measured for they were below WHO standard. This showed that clays have high potentials for pollutants removal.
