Bawat BaaS – Ballast as a Service
With Bawat BaaS – Ballast as a Service you don’t need to invest in a new onboard ballast water management system (BWMS) or own your own Mobile BWMS unit to stay compliant. Our mobile ballast water treatment units can be deployed to ports and shipyards worldwide-often within 24 hours-treating ballast water on demand and on location. You simply pay per cubic meter treated, making compliance both cost-effective and reliable.

Meet Bawat
Proven technology that delivers reliable ballast water treatment worldwide
With Bawat BWMS, service and maintenance are simplified. Using standard marine components in a simple system means the crew is already familiar with them. No costly or time-consuming procedures are needed – troubleshooting and maintenance can be handled by on-board personnel.

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.

Bawat develops technologies for ballast water management that meet environmental regulations at sea.
Bawat’s revolutionary one pass solution works for all water types and temperatures, anywhere in the world, ensuring complete D2 and USCG compliance. See how the Bawat technology works.
Frequently asked questions
Is the system IMO- and USCG-approved?
Yes. The Bawat Ballast Water Management System (BWMS) is both IMO Type Approved and USCG Type Approved, allowing vessel owners to comply with ballast water regulations globally.
Does the system require filters?
No. The Bawat BWTS operates without filters, eliminating the risk of filter clogging, backflushing requirements and maintenance associated with filter-based ballast water treatment systems.
Can the system handle high sediment or muddy water?
Yes. The Bawat BWTS is designed to operate independently of water quality. As it does not use filters or UV treatment, system performance is not affected by high sediment loads, turbidity, salinity or challenging water conditions.
What is a Bawat BaaS Reception Facility?
A Bawat BaaS reception facility (PRF) is an onshore mobile treatment setup located at a port or yard. It uses the same one-pass pasteurization technology as the Bawat BWMS and Mobile BWMS but is fully operated by Bawat personnel.
