Ballast Water Treatment System

IDRO Group system to treat ship's ballast water


A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide stability for a vessel

Ballast water taken into a tank form one body of water and discharged in another body of water can introduce invasive species of aquatic life: macroinvertebrates are transported by transoceanic and coastal vessels arriving in ports all over the world.

In order to avoid this environmental and economic damage all ships need to install an on-board ballast water treatment plant.

Treats ship ballast water using a system of UV filtration and DISINFECTION which renders microorganisms innocuous and guarantee discharge levels within allowed limits.

The filtration system is delivered as a compact-module, where there is need to economize on space, ready-assembled and mounted on a skid with all necessary equipment and prefabricated pipework.

Approved by revised IMO-G8 standard and U.S. Coast Guard (ESCG), Water Ballast System is certified for ballast water treatment in all types of water: fresh, brackish and marine.

The following components are incorporate into the Ballast skid:

  • the filter is used during ballasting operations to block the intake of larger organisms and reduce sediment in the ballast water tanks.
  • reactor, built in stainless steel comprises the enhanced UV treatment stage responsible for biological disinfection.
  • compact Cleaning in Place CIP unit, UV lamp performance is safeguarded by an automatic CIP cycle that removes UV-impairing fouling and scaling.

The Drive Cabinet and Control Panel are integrated into a single electrical cabinet.
The system is delivered as a compact-module easy to connect and is pre-tested before delivery.
