Ballast Water Filter aquaBoll® with adaptive filter elements

Ballast water filter aquaBoll® 

The aquaBoll® is an automatic self-cleaning pre-filter for ballast water management systems. The aquaBoll® removes organic particles and sediments from ballast water and serves as a solid protection of the ballast water system. The compact automatic filter is embedded in the system between the coarse filters and the chemical or physical disinfection unit.

The adaptative filter elements either of candles or of fine sieve cylinders are able to reach the defined precise degree of filtration down to 10 µm. The aquaBoll® is sea water resistant and available either as cast iron or carbon steel rubber line version. Its multi-part housing construction enables a flexible positioning of the connections and an easy maintenance.
