Technological achievements
Development of the ozone feeding and dispersion system is completed, and development of the process control unit involving prototyping of the hardware and validation of the software is in its final stage. The integrated BioFoulControl system will be installed and verified on board a vessel in the next reporting period.
The developed ozone feeding and dispersion unit manages generating micro-bubbles with average diameter of < 50ยต as envisaged in the project objectives. All larvae of the blue mussels can be eliminated at the TRO level stipulated in the objectives of the project with continuous ozonation. The level of bromates generated under ozonation is more than 300 times less than the level set in the objectives of the project and what is considered to be hazardous to aquatic life. There are no references on the limit of halocarbons, but the generation of bromoform needs to be addressed in the next phase of the project considering potential limits that may be set by IMO or individual governments.
