BWMS technology for Ports and Harbours
Ports, terminals, and shipyards all over the world are constantly seeking to improve their service and reduce their environmental impact. At the same time, flexibility is key, which is why Bawat has developed a mobile, containerized and self-sufficient solution for efficient ballast water treatment based on pasteurization technology - Bawat BaaS - Ballast as a Service.
ABOUT PASTEURIZATION
Pasteurization was invented by French scientist Louis Pasteur in 1862. Pasteur discovered that heating beverages was enough to kill most of the bacteria that caused spoilage, preventing these beverages from turning sour. Today, pasteurization is still used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.
HOW WE USE PASTEURIZATION
Bawat BWMS is based on unique patented technology, which represents maybe the simplest solution to an ecological and regulatory issue within the international shipping industry.
The heart of the Bawat system is the pasteurizing unit. Here, the ballast water is heated to a certain temperature via plate heat exchangers. Depending on the treatment temperature applied, ballast water is kept at this elevated temperature for a short period. The combination of elevated temperature and retention time in the pasteurizing unit ensures efficient elimination of all living organisms.
Within the regeneration section of the unit, the already treated ballast water pre-heats the in-coming water resulting in low power requirements and high energy efficiency.

ONE-PASS
DE-BALLASTING TREATMET
One pass through the system and ballast water is ready for discharge
ONE-PASS
TANK-TO-TANK TREATMENT
Ballast water is shifted from one tank to a clean tank through the pasteurization unit.
ONE-PASS
BALLASTING TREATMENT
Ballast water is pumped from the sea to the pasteurizing unit and then to a clean ballast tank.
ONE-PASS MOBILE
DE-BALLASTING TREATMENT
Exploiting the efficiency of the one-pass mobile solution, untreated ballast water is pumped from a ballast tank through the mobile BWMS unit and directly overboard.
