Advanced Treatment Technology
The NB-200 employs a sophisticated three-stage treatment process:
1. Mechanical Filtration Stage
-
Removes organisms and solid particles >50μm
-
Automated high-pressure backflush system
-
Differential pressure or timer-controlled cleaning cycles
2. Membrane Separation Stage
-
Removes microorganisms and particles >10μm
-
Gas-water mixture backflush maintenance
-
Significantly reduces sediment accumulation in ballast tanks
3. Nitrogen Deoxygenation Stage
-
Generates nitrogen from ambient air using molecular sieve technology
-
Creates anoxic environment that eliminates aquatic organisms
-
Provides corrosion protection for ballast tank structures
