Marine Nitrogen Ballast Water Treatment System
Brief Introduction
This type of BWMS is modular design, flexible layout, and small maintenance space required; no more breeding of organisms in the ballast tank, suitable for Long and short voyage; nitrogen feeding and de-oxygenation can effectively delay bulkhead corrosion; membrane separation technology reduces sediments in ballast tanks; energy consumption is only 1/3 of other treatment systems, which is the lowest in the world, and no limitation on salinity , temperature, turbidity, and etc.

Treatment Technology
Mechanical filtration - high pressure back flush to ensure flux;
Membrane separation - reducing sediments and delaying cleaning;
Nitrogen feeding and de-oxygenation - kill organisms and prevent corrosion.
Composition
1.Filter Units
It is used to remove organisms and solid particles greater than 50μm, and carry out High pressure and suction back flushing of the filter core under differential pressure or timer.
2.Membrane Separation unit
It is used to remove organisms and solid particles greater than10μm, and performing gas-water mixture back flush on the membrane elements under the control of differential pressure or timer.
3.Nitrogen Generator
The nitrogen generator uses air as the material and uses molecular sieves to selectively adsorb nitrogen and oxygen.
4.Control Unit
It has Automatic and manual control system operation, used to monitor the operation status of the system and record system operation information.
