The overall goal of this project is to asses the feasibility of using clay to filter water contaminated with organic contaminants. The clays that were used were provided by the Union Carbide Corporation and the Industrial Mineral Ventures (IMV), a division of Floridin company. The organic contaminants that this project concentrated on were, naphthalene, 1,4-dioxane, and phenol. The feasibility studies were done by batch isotherm studies. The protocol for the batch studies were the same as the ones used previously for granular activated carbon. This project looked at a total of six Union Carbide clays and five IMV Floridin clays. The batch studies reduced the number of clays that could be used for the removal of organics by eliminating the clays that adsorbed the least amount of contaminants. This showed which of the clays were best for removing the contaminants. The batch studies showed that the IMV Floridin clays were the best for adsorbing the contaminants.
