The Bawat BWMS is designed specifically for each ship based on an assessment of available excess heat, amount of ballast water to be ballasted/de‐ballasted during cargo operations, number and design of the ballast water tanks, trade pattern etc.
System Layout
- Circulation pump: Ballast water is pumped through the system by the circulation pump.
- Heating section: In the heating section, ballast water is heated to the specified temperature by plate heat exchangers by using waste heat from the main engine or other available heat sources.
- Retention section: The temperature achieved in the heating section is kept for a given time in the retention section.
- Regeneration section: After pasteurization, the ballast water passes through the regeneration section, acting as a pre-heater of the incoming ballast water, and cooler for the outgoing ballast water.
- Control and monitoring unit: The CMU controls the treatment process and logs all process data.
INSTALLATION
The Bawat BWMS consists of proven marine components, making the system highly flexible for implementation in almost any ship type and size - independent of ship’s ballast pump capacity.
Each Bawat BWMS installation is unique in terms of design by taking the ship's layout and heating system arrangement into account during a meticulous design process.
The Bawat solution can be designed as a central unit application or as a port and starboard side application. The system can also be delivered partly or fully skid-mounted or in a shipping container sizing 20’ to 40’ depending on system specifications.
The Bawat BWMS is particularly suited for retrofit applications as the individual components do not need to be in immediate vicinity of each other, giving the system great flexibility with respect to installation.
