Without ballast water, modern freight shipping is inconceivable. Each year, between ten and twelve billion tons of ballast water are transported by ships. However, it presents a considerable ecological problem all over the world.
When ballast water is taken on board in the port of origin to stabilize a ship and discharged in the port of destination, the organisms contained in the water are also brought to new habitats. Bacteria, plankton, viruses, small fish, crabs or jellyfish get into ecological systems which could sustainably change due to the new types. This is why the treatment of ballast water is legally required.
The two main ballast water regulations for the shipping industry were implemented by the International Maritime Organisation (IMO) and the United States Coast Guard (USCG). The IMO type approval will be a worldwide requirement. The USCG approval however is already required for all US water.
The Optimarin ballast water treatment system equiped with the BOLLFILTER Automatic Type 6.18.3 is already USCG approved.
For the Ballast Water Management System (BWMS) on large ships, there are numerous solutions. To protect these multi-stage systems for the treatment of ballast water, the majority of the systems require automatic prefiltration of the sea water taken on board. Therefore, a fine filter is installed between a coarse separator and the chemical or physical disinfection units. Its task is to remove animal and vegetable organisms, as well as sediment from the ballast water.
The BOLLFILTER Automatic Type 6.18.3, for automatic prefiltration of sea water, presents inexpensive top technology for new construction, retrofitting as well as solid protection for ballast-water treatment systems.
