CleanBallast - technical information

In-depth disk filtration and electrochemical disinfection: a combination that convinces customers and achieves best results.

The RWO DiskFilter solution

Advanced mechanical separation

With the DiskFilter solution in the CleanBallast® system, even the smallest sediments are reliably removed by special in-depth filtration, giving you all the advantages, like less fuel-consumption, no loss of cargo weight and avoidance of expensive tank cleanings.

During ballasting particles, sediments and organisms that are larger than 55 μm are removed by means of mechanical filtration in parallel working DiskFilters.

The RWO Screen Filter option

Finest filtration for your retrofit

RWO's Screen Filter solution bases on a self-cleaning multi-screen filter and is a real alternative to the proven DiskFilter.
The new technology consists of on a multi screen design combined with a suction scanning mechanism and demands a much lower footprint compared to the proven DiskFilter.

With the new screen filter RWO offers a reliable option especially for retrofit projects, where space is limited and additional conditions have to be considered in the planning process. The advantages are obvious:

  • Reduced footprint
  • Reduced piping efforts
  • Less power demand
  • Excellent effluent results

Advanced electrochemical disinfection

RWO Ballast Water Treatment

The further disinfection of the filtered ballast water is obtained by the advanced EctoSys® electrochemical cell, which reduces the number of living organisms and disinfects the water before it reaches the ballast water tanks.

The ballast water treatment convention is a discharge standard and natural regrowth and reproduction of any remaining organisms in the ballast water tanks can occur during the voyage. Therefore prior to discharge the ballast water is treated a second time by the EctoSys® cell. In this way a disruption-free and clean water cycle is ensured, from taking in to pumping out, to ensure that the performance standards as set by the regulations are met.
