In something of a breakthrough for domestic ballast treatment system makers, Ecochlor has become the fifth maker to achieve USCG type approval.It is the first chemical injection treatment system and the first from the US.
After a detailed review of the manufacturer’s type approval application determined the system met the requirements of 46 CFR 162.060, the USCG issued its type-approval on 10 August.
The system already received final approval for its active substance under the IMO G9 process in October 2010 and IMO type-approval in November 2011. The treatment principle of the Ecochlor BWTS is based on a three-step process consisting of filtering and chemical injection on uptake, along with in-tank sampling of chlorine dioxide concentrations. This approval covers fourteen models with maximum treatment rated capacities between 500 m3/h and 16,200 m3/h.
The other four USCG type-approved systems are Optimarin and Ocean Saver systems from Norway, Alfa Laval from Sweden and SunRui from China. Several more makers are expected to obtain USCG type-approval this year. The next system most likely to achieve type-approval is the Erma First FIT system from Greece for which the application was presented in early May and is now under review.
