Host Institution: Cooperative Institute for Limnology and Ecosystems Research (University of Michigan College of Engineering) and the Great Lakes Environmental Research Lab (National Oceanic and Atmospheric Association).
Location of Research: Ann Arbor, Michigan
Funding Level: US$306,000
Funding Source: Great Lakes Fishery Trust Fund
Timeframe of the project: March 1998 - February 2001
Aims and objectives of the project:
To investigate the potential for biocide treatment in helping reduce the number of nonindigenous species released into Great Lakes' waters.Components of this objective are to establish the concentrations of glutaraldehyde required to achieve 90% mortality rates (LC90) in 24-hour water-only exposures using a range of representative aquatic organisms; Determine the effect of sediments on glutaraldehyde efficacy in 24-h water-sediment exposures; Measure degradation rates of glutaraldehyde under conditions similar to those found in ballast tanks; Determine the concentrations of glutaraldehyde that may pose a risk to organisms exposed in receiving waters; Conduct a field trial of glutaraldehyde treatment using a foreign NOBOB (no ballast on board) vessel transiting from the Baltic area to the Great Lakes.
Reasearch Methods:
Laboratory testing, which included a 24-hour acute lethal toxicity bioassays, chronic toxicity bioassays, degradation experiments and shipboard application (still in development).
Results:
To be determined
Name of project: Suggested Designs to Facilitate Improved Management and Treatment of Ballast Water on New and Existing Ships
Treatment option researched: Design options for ballast water exchange (sequential and flow-through), heating via main engine cooling water, chemical, filtration, hydrocyclones, ultraviolet irradiation, fresh or recirculated water, discharge to shore based or dedicated treatment ships and best practice design aspects related to sea chests, ballast tanks (especially strength, water flow and minimisation of sediment accumulation), ballast pumps and pipework and chain lockers in relation to sediments.

Host Institution: Alan H Taylor & Associates and Reninna Consulting.
Location of Research: Australia.
Funding Level: Approximately AUD$15,000.
Funding Source: Funded from the Australian Quarantine and Inspection Service Ballast Water Research Programme budget which has come from a levy on ships calling at Australian ports.
Timeframe of the project: Project completed January 2001
Aims and objectives of the project:
To suggest designs to enhance ballast water management on new and existing ships.
Reasearch Methods:
Review of designs of existing ships and new ships and develop further designs and enhancements to facilitated better ballast water management.
Results:

Host Institution: Northeast-Midwest Institute
Location of Research: Barge-based tests: Duluth-Superior Harbor, MN and Two Harbors, MN; Ship-board tests: M/S Regal Princess Vancouver to Alaska voyages.
Funding Level: Approximately $600,000.
Funding Source: US EPA Great Lakes National Program Office, National Sea Grant Association, US Coast Guard.
Timeframe of the project: Field work took place May-September 2000. Sample analysis is on-going.
Aims and objectives of the project:
To develop protocols for assessing biological and operational effectiveness of ballast treatments on a barge-based platform and ship installation; to assess and compare the relative effectiveness of filtration/UV and cyclonic separation/ UV under field conditions at a flow rate of 1500 gpm; to draw conclusions about the generalizability of barge-based information to ship context.
Reasearch Methods:
Barge-based biological tests involved sampling triplicate matched treatment and control collection tanks at two time intervals and turbidity levels. Samples were subjected to live/dead and density analysis of zooplankton; total chlorophyll a, growth rate, and density analysis of phytoplankton; inactivation rate of a spiked MS 2 bacteriophage; and total bacteria counts. Particle removal, flow rate, and power consumption were meansured. M/S Regal Princess tests involved three before/after in-line tests; three ballast tank “time zero” tests (water was placed in matched treatment and control ballast tanks and then removed immediately); and three ballast tank “retention tests” (water was retained for 18-24 hours). Samples were analyzed for density/inactivation of zooplankton, phytoplankton and bacteria.
Results:
To be determined.
