40 micron backflushing filter system.

No effective ballast water treatment without proper filtration.

A crucial first step in UV and EC ballast water treatment is the filtration of all incoming seawater during uptake. We use high quality 40 micron back-flushing filter systems that deliver exceptionally reliable performance. They allow for a very consistent second stage treatment of the ballast water to IMO and USCG standards. Our filter systems are designed by our trusted partner FilterSafe®.

Poor filtration creates costly operational problems.

No 1st stage filter that determines the size of organisms leads to unknown required dose for treatment in stage 2. This allows for microorganisms to make it through to the 2nd stage, overwhelming the secondary treatment mechanism and getting out alive.

Built-up sediment in ballast tanks increases the ship's weight, hence the need for more fuel to sail.

Deep pockets of sediment, built up over a longer time, can start harbouring organisms.

Low quality filters end up in a state of constant backflush, constantly trying to clean themselves in order to stay functional because of their incapability to process the water.

The patented nozzleX technology cleans 100% of the filter screen every time, without any wear on the nozzle or the screen.

Benefits of FilterSafe® filtration:

40 micron filtration with a long screen life, thanks to duplex 904L construction made of the highest grade material available in the industry.

Continuous operation, even during backflush process.

Minimum chance of operational issues and blinding thanks to sensibly and sustainably sized mesh velocity.

Ability to recover from exceptionally high TSS situations with no operator intervention thanks to the right sizing.

Guarantee of exceptionally high strength and long reliable service of the screen while allowing for easy inspection of the mesh during the lifetime of the equipment.

Smooth screen design allowing for adequate handling of increase in differential pressure during high TSS events while recovering quickly.

Low backflush flow rate requirements during self-cleaning process.

Simple and easy maintenance.

How the filtration system works.

Marine engineer installing and servicing a ballast water filtration system onboard a vessel.

Water starts its journey to the ballast tank by being pumped onboard. It may go immediately to the filter or have to travel a distance across the ship to get there. Once it arrives at the filter, it goes through a prefiltration section that removes large particles. The smaller particles then enter the filtration chamber where organisms and dirt are trapped by the screen. As more and more particles build up on the screen, a sensor recognizes a difference in the pressure of the water coming into the filter and going out of it. This triggers the automatic self-cleaning cycle, where the dirt on the screen is sucked up by the nozzles and is dumped overboard. The pressure returns to normal and the filtration continues. At this point the water is ready to go to the secondary treatment stage to be neutralized before filling the ballast tanks.
