  • Patent number: 5368753
    Abstract: The invention is an antifreeze reclamation system that is designed for low volume processing over extended time periods. The system makes use of a tank that is preferably fabricated from a standard fifty-five gallon drum. Attached to the top of one end of the tank is a standpipe used for inputting used antifreeze into the system. A second standpipe is located at the top of the opposite end of the tank. The system functions by allowing gravity, buoyancy and time to separate the used antifreeze from entrained and dissolved impurities. The outputted liquid is mixed with new materials to restore it to its original, unused condition.
