The use of a leading-edge technology

BIO-SEA conceives water treatment solutions specifically designed for the disinfection of organisms contained in ballast water.

BIO-SEA has combined two technologies in a single one automated unit:

Mechanical filtration technology

mechanical filter for ballast water treatment The system first cleans ballast water using a screen filter, in order to reduce the amount of total suspended particles, organic (or not) being present in the seawater.

UV disinfection technology

uv reactor for disinfection of ballast waterIt disinfects the water and eliminates all the microorganisms. Without any additional chemical product or active substances, the water passes through a reactor where UV rays destroy microorganisms DNA.

Automated technologies

cabinet control for automated operations of ballast water treatmentAutomated monitoring and control. All operations carried out to treat ballast water are automated thanks to sensors.


Treatment during ballasting operations:

While ballasting, both operations of filtration and UV disinfection are carried out to limit the loading of suspended solids and living microorganisms in the ballast tanks, which maximizes water exposition to UV-C rays.


Treatment during de-ballasting operations:

While de-ballasting, only the operation of UV disinfection is completed. This allows re-treating the water that stayed in the ship's ballast tank during the journey, in order to eliminate the possible biological re-growth, to ensure compliance with the IMO standards.
UV disinfection only - filtration is automatically by-passed


Cleaning Operations:

At the end of operations (either ballasting or de-ballasting) a full and automated purge of the system is performed, followed by the filter and UV reactors flushing and filling with fresh water.
