Shipboard Oil-Pollution Control Systems for Ballast and Bilge Waters. A State-of-the-Art Search
Abstract
An investigation was undertaken to provide U. S. naval combatant ships with the capability of avoiding oil pollution in excess of 100 parts of oil per million parts of seawater in their discharges of ballast and bilge waters. Examination of the open literature and patents as well as discussion with Government and industrial specialists revealed that: (1) no available technology, alone, is practicable for shipboard reduction of the oil content to points below the required limit; (2) a combination of two or more operations along with reprocessing might be suitable for the purpose; and (3) reliable devices for measuring oil content in water are needed for satisfactory solution to the problem. Since no single means has been found, however, the development of a process has begun. The first goal is to solve the bilge-water/oil pollution problem, which appears simpler, and then to extend this solution to the ballast- water/oil-pollution problem.
