Sintered Filters For The Ballast Water Treatment Industry - Easy To Be Back Flush

Ballast Water Filteration Treatment systems are also susceptible to a number of technical constraints which are especially concerning in retro-fit projects. Often, the key design constraints of these systems revolve around filter footprints as well as access for installation and maintenance (both critical factors in being able to install a system in non-compliant vessel). However, other key concerns include the specification and location of existing system infrastructure namely the ballast water pump size and its location. This often leads to pressure concerns at the inlet of a system as it is not uncommon to have a ballast water pump some distance from the location of the retro-fit system (especially noticeable in large vessels like a VLCC vessel which require flow rates of up to 7400 m3/hr).

Regulatory convention and agreements

The two main ballast water regulations for the shipping industry were implemented by the International Maritime Organization (IMO) and the United States Coast Guard (USCG). The IMO type approval will be a worldwide requirement where the USCG approval is already required for all US water.

This is how the filtration of ballast water works

For the Ballast Water Management System on large vessels, there are numerous solutions available. To protect these multi-stage ballast water treatment systems, the majority of the systems require automatic pre-filtration of the sea water taken on board. Therefore, a fine filter is installed between a coarse separator and the chemical or physical disinfection units. The filters task is to remove living organisms, as well as sediment from the ballast water.
