Pre-filtration of ballast water management systems

The fully automated filtration solutions by BOLL & KIRCH are one of the key elements in ballast water management systems used on a wide range of deep sea vessels.
Using a BOLLFILTER as a pre-filter ensures trouble-free functioning of these sensitive, multi-stage systems. This filter removes organic particles and sediments from ballast water up to a particle size of 50 μm with great efficiency. Thanks to its innovative design and optimised functionality, the BOLLFILTER guarantees the necessary filtration quality even at the highest of flow rates. The compact automatic filters are embedded in the system between the coarse filters and the chemical or physical disinfection unit.

The Optimarin ballast water treatment system including a BOLLFILTER was the first U.S Coast Guard approved system.

MV “STELLA IVY” is a 250,000 DWT ore carrier equipped with the Balclor® Ballast Water Management System (BWMS) from the company SunRui Marine Environment Engineering Co, Ltd. This equipment, which has been USGC approved, consists of:

BOLLFILTER Automatic which removes marine organisms larger than 50 µm.
Electrolytic unit which disinfects the ballast water.
Neutralizer which reduces the total residual oxidants (TRO) in the ballast water to below 0.1 ppm.
