1. Costs—capital, operation and maintenance, unit treatment costs:

    System operation, maintenance, and reliability:

  2. Training/Manning:

  3. Monitoring capabilities (monitoring capabilities built into the system, or requires additional equipment):

  4. Residuals formed during the use of the technology (chemicals or gases remaining after the process):

  5. Retrofit capabilities (requires dry-docking a vessel, or can be retrofitted while afloat):

  6. Safety concerns (human health threat or danger in application of this technology?):

  7. Similar installations (any examples of where the equipment has been used or tested successfully):

  8. Special permit requirements:

Application Considerations of Technologies
  1. Effects of salinity levels of 0 to 30 parts per thousand or specific gravities of 1 to 1.025:

  2. Effects of temperature (does temperature have any impact on the operation of the proposed equipment?):

  3. Effects of sediment loads up to 10 percent (sediment load directly impacts the turbidity, and this may have a negative impact on some types of treatment such as infrared):

  4. Effects of increases in treatment goals on how well the system performs:

  5. Effects of ship motions:


Completed responses were received from the following suppliers, developers, and research organizations:

Alten Water Treatment Corporation, Palo Alto, California: ozone treatment (P)1

Aquafine Corporation, Valencia, California: ultraviolet treatment

Center for Advanced Ship Repair and Maintenance (CASRM), Inc., Norfolk, Virginia: pulsed electric field treatment (P)

Defence Research Establishment Atlantic, Halifax, Nova Scotia, Canada: ultrasonic treatment


 (P) indicates that a representative from the named organization also gave a presentation to the committee at one of the technology workshops (see Appendix B).
