Why is ballast water management important?

Ballast water management is important because it prevents the spread of invasive organisms and pathogens through ballast water. Ballast water is used to provide stability to ships during loading and unloading of cargo.

When ballast water is transferred from one area to another, harmful organisms and microorganisms can be released, posing a threat to the local ecosystem and public health. By implementing a ballast water management system, this risk is minimized, ensuring the preservation of biodiversity and the sustainability of waterways.

How the Headway Oceanguard works

Headway Oceanguard is a single treatment system specifically designed for ballasting. It treats ballast water, whether it is seawater, brackish water, or fresh water.

In ballast mode, the water first passes through a 50-micron filter before entering the Electro Ultraviolet Treatment (EUT) unit. The EUT utilizes electrocatalysis to eliminate any remaining organisms in the ballast water. This process generates a significant number of hydroxyl radicals (OH¯), which are negatively charged and react with microorganisms, effectively killing them.

In the Ballast Water Management System (BWMS), if the salinity of the ballast water exceeds 3 ppm, a small amount of Total Residual Oxidant (TRO), including chlorine, is formed. The Monitor Unit measures the TRO level, which is then used by the BWMS to regulate the current for the EUT. The normal TRO range during operation is between 1.8 ppm and 2.2 ppm. If the water's salinity is lower, the TRO value will be lower or absent, and the current to the EUT will be increased to ensure sufficient hydroxyl radicals (OH¯) are produced to eliminate all organisms.

Once the ballast water is in the ballast tank, the average TRO value of 2.0 ppm gradually decreases to 0.1 ppm within approximately 24 hours.


During de-ballasting, the ballast water is discharged directly overboard, and only the TRO value is measured. If the TRO value exceeds 0.1 ppm, the Neutralization Unit automatically activates and injects "Sodium Thiosulfate Pentahydrate" to neutralize the TRO.
