Ballast Water Management System

ships ballast water - the problem?






how does it work:


1. Sea Water

The sea water from the uptake is first treated by the ultrasound transducers fitted in a acoustic enclosure at the stern of the vessel to provide cavitation in liquid, which con lead to the cells organisms rupturing. Ultrasound cavitation is very effective with bacteria, plankton and other large organisms.
2. Treatment Tank

Ballast water is treated with combinations of technologies in a specially designed high pressure cylindrical tank of capacity 200 cubic meters. The tank is ideally located at the stern of the vessel, above the mooring winches and well clear of any working obstructions.
The uptake sea water is delivered to this treatment tank by the ships main ballast pump via the high pressure booster pump at a pressure of 10.00 kg/cm2.

The sea water is impacted on the inner periphery of the treatment tank under pressure, atomizing the water particles into fine droplets mist, which in turn breaks down the body structure of the pathogens. Simultaneously, inert gas is introduced into the tank by independent source of Nitrogen generator. This action causes asopyxia and total breakdown of pathogens / bacterias.
3. Sand filter:

The sea water contained in the high pressure treatment tank is then passed into a sand filter located below the treatment tank for filtration purposes. The sand in the sand filter is thoroughly sanitized before every ballast water treatment operation by fitting of steam coils and propellers to churn the sand for effective sanitization. Before every operation the sand filter is thoroughly washed by hot steaming water of 80o to 90o C and all the dirt and remains of the dead organisms are disposed off by incinerating.

Due to high pressure of 8.00 kg/cm2 in the treatment tank, the sea water is forced hard into the sand filter, thus allowing for high flow rates of ballast water to be easily handled. Due to sand filter, the tanks are free from any sediments generation; when ballast water is taken from river ports, estuaries etc.

4. U.V. treatment

The filtered water from the sand filter is then passed through the low pressure U.V. lamp of 254 nanometers range. 254 nanometers is the optimum wavelength for inactivating micro-organisms ( viruses, bacteria, algae, yeast mold). U.V. light penetrates to the heart of the micro-organisms, DNA and disturbs the metabolism of the cells. All the germs are thus inactivated ( including legionella and cryptosporidium ) and can no longer reproduce.

The UV radiation induces photochemical changes in the organisms; which will break the chemical bonds in DNA. To increase the performance and efficiency of U.V. treatment, the positioning of the U.V.lamps are such that only clean & filtered water passes through these lamps after effective filtration from the sand filter.

how is sea reliance different from other vendors?


Sea Reliance treats volume of water in a highly pressurized tank with inbuilt combination of technologies, and allowing sufficient curing time for total eliminations of pathogens. This is the main difference; where as most of the vendors of the ballast water treatment technologies have their system based on Online treatment.
