InTank® Ballast Water Treatment

Treat Ballast Water Where It Sits – In the Tank

InTank® is a revolutionary ballast water treatment system that disinfects water directly inside the ballast tanks, eliminating the need for high-flow filtration during ballasting. This gives ship owners the power to treat ballast water after loading, without disrupting cargo operations or port schedules. InTank® = InVoyage™ + InControl™ + InCompliance

Why Choose the InTank® System?

InTank® offers a smarter, more flexible approach to ballast water treatment by disinfecting directly inside the tank. Ideal for vessels with limited space, challenging water conditions, or tight schedules, this system helps shipowners stay compliant without disrupting operations.

Treats Ballast In Place
No need for high-flow filtration during ballasting. Treatment happens post-loading, inside the ballast tank.
Unmatched Operational Flexibility
Perfect for vessels with long voyages, poor port water quality, or limited downtime between port calls.
No Disruption to Cargo Operations
Ballast water can be treated after departure, allowing full focus on port logistics and loading schedules.
Compact and Portable Options Available
InTankFITT, developed with Uniballast B.V., provides a portable treatment solution for vessels that cannot install a permanent system.
Fully Compliant
All InTank systems meet IMO Ballast Water Management Convention and MEPC.127(53) requirements.

How It Works

The InTank® system treats ballast water directly inside the tank using a recirculation and chemical injection process. This method allows treatment to occur during the voyage, with no impact on port operations or cargo handling.

  • Wastewater remains in the ballast tank during the entire process
  • Chemical treatment and recirculation begin after departure from port
  • Treatment continues over the course of the voyage, typically 36 to 48 hours
  • Disinfection and neutralization occur in-tank and are confirmed before discharge
  • No filtration, no power use in port, and no dependency on water quality
