Biological growth in sea water systems is far more complicate than in other industrial cooling systems.

The reason is because :

• Sea water ecosystems are more extended than the conventional industrial cooling water ecosystems.

So except microorganisms,

We have to face greater fasma of bigger and more resistant creatures

Practically is not allowed to kill marine life, so the biological control should be different.

Finally, sea water cooling systems are using large water volumes, so if we try to treat them as conventional industrial cooling water systems, the treatment cost will be enormous
