Fine filtration solutions for Exhaust Gas Cleaning Systems

BOLL & KIRCH, as an experienced technology specialist, offers tailored solutions for Exhaust Gas Cleaning Systems (EGCS) also known as “scrubbers” suited to remove large volumes of contaminants and particulate matter.Safe and reliable compliance of the treated water with the IMO MEPC.259(68) discharge criteria is mandatory for our fine filtration solutions.

One application, two benefits!

The BOLL FineFilterUnit is a complete water treatment system based on advanced membrane technology. The BOLL FineFilterUnit cleans the scrubber washwater and optionally, the make-up filter ensures the efficient protection of the EGCS.
Closed loop systems need constant replenishment of water. Over time, the particle concentration in the washwater will increase, the washwater in the exhaust gas cleaning system has to be partially purged. At the same time some water evaporates while cooling down the exhaust gas. Thus, additional technical water is added to the closed loop system before being filtered. This is usually done with technical respectively fresh water or with seawater.
Using seawater for make-up, the aquaBoll® efficiently removes organic and inorganic particles from the water by ensuring fully automated filtration and thus protection of the EGCS.

Your Benefits:

  • 100 % compliance with the IMO regulation for treated washwater discharge
  • No use of chemicals during the treatment process
  • Small footprint enabling easy retrofit
  • Outstandingly long lifetime of the membrane due to efficient protection
  • Low maintenance due to automated systems
  • Modular design
