Clay Ceramic Pellets for Water Treatment

Two different Quaternary clays from deposits Slucenieki and Prometejs were used for production of porous ceramic pellets. 3 wt % of sawdust additive was used to increase porosity of the obtained ceramic. Porosity and surface area of pellets was determined by mercury porosimetry. pH values after water immersion of fired pellets were determined using a pH meter. Pellets produced from both clays after sintering at similar temperatures had different pore size distribution and different sorption properties. Sorption properties were determined for a molecular substance (iodine) and anionic organic substance (methyl orange dye)
