What is an RO (Reverse Osmosis) Membrane?
-“RO” stands for “Reverse Osmosis” and the RO Membrane is an advanced filter which can purify even sea water to be pure enough to drink*. The fibers of the
RO Membrane are so fine (1mm/10Mil) and it only let water molecule through.
That is why the RO Membrane can produce pure water from sea water.
Pros & Cons of RO Equipment
Pros
- Steady water production under any conditions – even in Stand-By mode/decelerated operation mode/rough weather conditions
- Minimizes frequency of shore fresh water supply
- Produces much more water without using waste heat, which makes the plant compact than evaporator types.
- Easier maintenance, lesser workload for crew with automatic operation
- More space for cargo, replacing with shore supplied water
- Reduces waiting time for shore supplied water
Cons
- Operation is limited at contaminated river (mud)/sea ports (same as evaporator)
- RO Membrane requires regular replacement (every 3-5 years)
- Chemical/filter requires regular replacement
- (When installing to existing vessels) Installing space is required in the engine room (carried out during Dry Dock)
Appearance/Specification
- Easy operation by following instructions on the touch panel
- Less time/complexity for component replacement
- Maintains high water quality by using a unique slime control chemical,which Kurita developed
- Minimizes your crew’s workload by operation/maintenance manuals that are easy to understand
