aquaBoll BWT as pre-filter of ballast water treatment systems

Modern ballast water treatment systems require good ballast water pre-filters to meet the strict discharge requirements. The aquaBoll® BWT was developed for these requirements of fine filtration to 20 µm with simultaneous large flow rates of up to 3000 m3/h seawater.

The compact series is matched to the system performance and pump capacities of the treatment systems on board. A large screening area and a new type of backwash arrangement allow safe operation with a wide range of water qualities and high dirt loads. 

Cost savings through a fully automatic ballast water filter

Due to automatic backflushing, perfect regeneration of the filter mesh is ensured. The filter, operating fully automatic, conforms to the regulations of unsupervised operation on ships. A continuous series with different sizes of housing and nominal connection widths, permit adapted dimensioning of the ballast water filter to individual circumstances.

Benefits of the BOLLFILTER aquaBoll BWT®

In the area of conflict between statutory restrictions, extreme technical requirements and high economic pressure, the aquaBoll BWT presents the ideal solution for ballast water pre-filtration.

The filter convinces technically and economically through:

  • the precise result of filtration,
  • the optimized effect of flushing,
  • its low space requirement and easy installation,
  • its economy in procurement and operation.
  • the high volumes of flow of sea water or ballast water per hour,
  • its durability, due to a robust construction and corrosion-resistant equipment,
  • its low maintenance and servicing effort,

The sea water filter for ballast water only demands a small installation area, which increases its suitability for use in new constructions and also for retrofitting. Its simple and robust construction makes it extremely maintenance-friendly and durable. The core of the filter is the filter element which, due to the specially developed backflushing device, enables extremely effective and quick cleaning without interrupting the filtration process.
