APPENDIX G Treatment Options Query

A ballast water treatment options query developed by the committee, which is provided below, was sent to suppliers and developers of candidate water treatment systems and to research organizations.

BALLAST WATER TREATMENT OPTIONS QUERY

System A: Flow rate of 2,000 cubic meters per hour, and tank volumes up to 25,000 cubic meters with residence times as short as 24 hours

System B: Flow rate of 20,000 cubic meters per hour, and tank volumes up to 25,000 cubic meters with residence times as short as 24 hours

For each of the two system flow rates described as System A and System B above, please complete the following query.

Technology Requirements and Capabilities
  1. Treatment technology name and developer or vendor:

  2. Typical application of technology (e.g., drinking water sterilization, etc.) OR is this technology at the experimental level:

  3. Typical treatment endpoints or goals (e.g., 95 percent to 99.9 percent removal or sterilization, species-specific biocide, etc.):

  4. Typical equipment requirements (configuration requirements such as in the tank or engine room):

  5. Space Requirements (length, width, and height in either feet or meters would suffice):
