If you need assistance complying with upcoming regulations for ballast water treatment systems of uv lamp, look no further. The MEPC (Marine Environment Protection Committee), a subsidiary number of the IMO (International Maritime Organization) is globally enforcing new standards for ballast water treatment systems for ships effective September 8, 2017. The current standard, known as the Ballast Water Management Convention, was utilized in 2004 following initiatives with the IMO to create procedures and standards for managing and controlling ballast water for ships. The new regulations take those procedures a little more forward.
The primary goal of these newly established standards and procedures to the management and treating ships’ ballast water is always to prevent the spread of harmful marine organisms derived from one of region completely to another. Under the new terms with the Convention, all ships driving international waters will likely be required to have ballast water treatment systems that remove or destroy aquatic organisms, pathogens and sediments that occupy their ballast water which has a ship-specific ballast water plan of action.
Tested under poor water quality conditions, on the list of lowest UV transmittances in the profession. Many existing IMO Type Approved systems are already tested in higher clarity water (high UV transmittance). It is expected these systems will be unable to treat lower clarity waters rather than to what they are already tested to under USCG regulations. The UV transmission value are going to be noted for the type approval certificate, significantly limiting the applicability with the system in poorer water qualities.
Disinfecting water while ensuring acute kill in the organisms instead on the ability to reproduce requires a much more conservative dosage, implying higher power consumption (3-5 times) from the UV lamps in comparison to most systems designed today. It may also imply more operational restrictions, for instance minimum holding times (inside a BW tank) and UV transmittance (UV-T) limitation for your BWMS. UV-T is one on the key limiting factors that UV BWMS is tested for, indicating the capability to irradiate “murky” waters. Treatment in harbours with low UV-T will potentially call for a reduction with the flow rate to raise the exposure the perfect time to the UV lamps thereby the dosage used on the water.
