Key benefits of our BWMS
No Chemicals
No more expensive chemicals and no impact from brackish water.
No Filters
No expensive filter maintenance and offhire.
No UV
Challenging water no longer an issue. No more reactor cleaning.
Independent of water quality
Works efficiently in all water conditions - no impact from turbidity, salinity, or temperature.
No Holding Time
One pass neutralises all organisms (D-2 Compliant).
No Impact on Cargo Operations
By-pass the BWMS during cargo operations. IMO and US Coast Guard Approved.
No Expensive Sensors
No TRO Sensors, UV Intensity & Transmittance Sensors or Turbidity Sensors. Our system only uses Temperature and Pressure sensors.
Heat Based
Uses pasteurisation - simply heating the water to remove invasive species and pathogens - a simple and proven solution.

Frequently asked questions
What is ballast water?
Ballast water is water carried in ships’ ballast tanks to improve stability and balance. Cruise ships, large tankers, and bulk cargo carriers typically take in ballast water from coastal waters after unloading cargo and later discharge it at their next port of call. This water often contains biological materials such as plants, animals, viruses, and bacteria — many of which can become invasive species and harm aquatic ecosystems or disrupt local economies.
What is the cost of a Ballast Water Management System (BWMS)?
The cost of a BWMS varies depending on the ship type, system capacity, configuration, and service requirements. For a price estimation, please send your vessel details to info@bawat.com.
What is the minimum and maximum capacity range for a Bawat BWMS?
Bawat BWMS units are available with treatment capacities from 5 m³/h up to 5,000 m³/h.
What is the main principle of Bawat BWMS operation?
The Bawat BWMS uses a unique, patented one-pass pasteurization technology. This heat-based treatment represents one of the simplest and most effective solutions to an ecological and regulatory challenge in the international shipping industry.
The main components of the Bawat system are standard components already present in vessels as heat exchangers, pumps or flowmeters.
