2. Evolving Needs and Differential Nature of Bilge Water • 15 ppm • What does it mean? • 15 / 10,000 of 1% • 15 gm / 1,000,000 gm • 1 ml = 1 gm = 1 cc • 1L = 1000 ml x 1000 L = 1 x 106 ml = 1 x 106 cc • 1000 L H2O x 1000 gm/L = 1,000,000 gm 2

3. Comparison of 1000 ml • Droplet volume 15 ml = 15 cc • # of droplets = 1 • Diameter of droplet = 3 cm • Surface Area = 28.6 cm2 • Mass >> Surface Tension • Charge << Mass • Will Disperse • Diameter of droplet = 1 micron • Droplet Volume = 5.24 x 10-19 cc. • Number of Droplets = 15 /( 5.24 x 10-19 ) = 3 x 1019 droplets = 3,000,000,000,000,000,000 droplets • Total Surface Area = 9 x 10 7 sq.cm • Mass << Surface Tension • Charge >> Mass • Will Repel 1000 ml 3

5. Nature of Bilge Water as Ship Ages

6. Evolving Needs and Differential Nature of Bilge Water • One size fits all approach is problematic due to variable nature of bilge water from ship to ship and over the lifetime of the ship • Shipboard bilge water systems should be modular and able to evolve as conditions change
