CMA CGM has contracted BIO-UV Group to supply its BIO-SEA ballast water management system (BWMS) to 17 containerships in a deal worth more than €5m.

Nine LNG-fuelled 22,000-teu leviathans currently under construction at China’s CSTC Shipyard will each be fitted out with two 3000m3/h capacity BIO-SEA B 10-1500 FX units, while eight 9000-teu capacity Opera-class vessels will be retrofitted with a BIO-SEA B 10-1000 FX unit capable of treating ballast water flow rates of 1000m3.

Xavier Deval, BIO-SEA by BIO-UV business director, said: “We are excited to be working with CMA CGM on these newbuild and retrofit projects, which represent the first orders since our USCG-approval.

“The order substantiates our view that BIO-SEA is one of the best ultraviolet treatment systems available. It is suitable for all waters of the world in which these CMA CGM vessels will operate and is one of the very few ballast water treatment systems that is currently compliant with both USCG and IMO requirements.”

No freshwater limit

The UV-type ballast water treatment system is available as a skid mounted, semi-modular or modular system capable of dealing with flow rates between 10 and 2000m3/h. To date, it is the only UV system on the market with no limit for freshwater retention, 24 hours in marine water, and 72h days for brackish water, said BIO-UV.

BIO-SEA is two stage treatment process, with ballast waters entering a 20µm filter to flush out any suspended solids and zooplankton. The filtered water then enters a titanium reactor to be put through the ultraviolet disinfection process.
