Filtration & Sterilisation
The Norwegian Greentech BWMS uses an environmental friendly combination of self cleaning filters for particle filtration and UV-light for sterilisation. Norwegian Greentech's filters are the most recognized filters in the Ballast Water Business today. With by far the longest reference list on the market, Norwegian Greentech also has the broadest experience in the industry.
- NGT filters consist of several filter candles made of super duplex steel (chrome-nickel-molybdenum) with a filtration degree of 40 micron
- A sacrificial anode provides perfect corrosion protection
- The filter's backflush pump installed as standard ensures efficient cleansing of the filter candles
- Fully configurational backflush setpoint
- Approximately 5-years service interval
The UV lamps used are designed to provide a guaranteed, fully effective life-time of 3,000 hours on maximum power – approximately five years on an offshore platform supply vessel. However, practice has proven that the device has a significantly longer lifespan.
