A process for physically and chemically treating a used engine coolant from a Domestic, European or Japanese/Asian vehicle containing one or more glycol and/or an alcohol-based antifreeze components. The process includes the steps of oxidation with one or more known oxidizing agents, precipitation with one or more known salt forming agents and filtration through any suitable filtration membrane or other separation means. A chemical additive has been developed for use in carrying out the process of the present invention which initiates and maximizes the amount of oxidation and precipitation occurring within the coolant composition, adds one or more suitable corrosion inhibitors and one or more known buffering agents in a sufficient amount to adjust the pH of the final solution. An apparatus (10) for use in carrying out the process of the present invention is also described herein. This apparatus includes container means (12) to receive used coolant, circulating conduit (15) and filtration means (32) to recycle the coolant. |
