| While the MTTC project that proved the value of system chlorination used devices that consumed chemicals, the same process is now being accomplished by electrolytic generators that provide chlorine directly from seawater. These devices have been approved and are on MCM class ships for at-sea testing. |

|
Problem:
| Biological growth in seawater firemains and cooling systems can completely foul the pipes and result in loss of system capability and requires expensive cleaning. Warm water environments accelerate the process.
|
Solution:
| MTTC, with Naval Research Laboratory and GeoCenters, Inc., designed, built and tested a portable device that chlorinated the seawater systems. A significant reduction in bio-fouling was documented with only single-source protection. |
Fleet Impact:
| Seawater system acid cleaning requires that the ship be taken off-line for several weeks and costs over $250 K. Fouling also causes degradation and failure of serviced weapon systems when adequate cooling is not achieved. Ship and weapon system reliability will be greatly enhanced when bio-fouling is eliminated. |
Applications:
| All ships home ported in warm-water locations.
All ships deploying to warm-water locations.
Fleet will procure rotating pool of chlorinators to cover above ships. |
