Claim:
1. A method for treating an aqueous chloride solution comprising the steps of: providing an aqueous chloride solution having heavy metals and organic compounds with at least a portion of the organic compounds forming an emulsion and a portion of the organic compounds including toxic organic compounds therein, pretreating the aqueous chloride solution to remove at least a portion of the organic compounds and heavy metals wherein the pretreatment comprises aerating the aqueous chloride solution and lowering the pH of the aqueous chloride solution to break down the emulsion, and oxidizing the aqueous chloride solution to remove the toxic organic compounds and remove heavy metals, and then simultaneously catalytically destructing residual organic compounds and removing residual heavy metals by injecting at least one oxidizing agent into the aqueous chloride solution as the solution is passed through a catalytic filter to form a clean chloride solution.
