| titleOfInvention | Vehicle coolant recycling |
| abstract | A process and apparatus for the treatment and recovery of spent vehicle coolant that involves the following steps: a) removing the spent coolant from the engine; b) treating the spent coolant with sodium dimethyldithiocarbamate to cause dissolved metals therein to form insoluble particles; c) treating the spent coolant of step b) with an aqueous basic coagulating agent such as a polyquaternary ammonium compound in its hydroxide form; d) filtering the spent coolant from step c) through a set of filters (35) and then through a bed (37) of carbon particles, to produce a relatively cleaner liquid; and e) adding to the relatively clear liquid a combination of corrosion inhibitors, buffering agents and alkali, whereby the treated coolant can be recycled to the vehicle for effective coolant performance therein. |
