  • Multichamber gravity operated oil-water separator
    Patent number: 6139730
    Abstract: An automatic oil-water separator which separates wastewater into oil or grease and water fractions is disclosed. The separator does not include any mechanical pumps in its structure and therefore does not generate oil or grease and water emulsions which are characteristic of separators using pumps and which are very difficult to separate. The separator is constructed without moving parts, filters or coalescing plates and operated without the addition of chemicals or the use of electricity.
