ERMA FIRST becomes the sixth BWMS supplier - and the first for a full flow electrolysis system - to gain US Coast Guard type approval

ERMA FIRST’s ballast water management system (BWMS) has become the sixth to receive US Coast Guard (USCG) type approval.

USCG issued a certificate on 18 October for the system, which uses a three-step process consisting of filtration and electrolysis during uptake and neutralisation at discharge.

According to a report on the USCG ‘Maritime Commons’ blog – where notices of type approval have been posted - the approval covers thirteen models with maximum treatment rated capacities between 90m3/h and 3,740m3/h.

The company, which submitted its final application for USCG type approval in April (six months ago), claims to be the first full-flow electrolysis unit to have applied for approval.

Konstantinos Stampedakis, managing director of Erma First said: “With the convention ratified and entered into force in September and the US Coast GUard implementation in place, the installation of a system is essential for the protection of the marine environment from invasive species. Erma First proves its capability to undertake and successfully complete challenging projects such as obtaining the type approval by the USCG.”

Helen Polychronopoulou, business development manager, Erma First, added: “ The units used during the USCG type approval process have remained identical since we started. Moreover, no modifications were made to the units already delivered to clients nor will be made to those to follow”.

Erma First’s FIT system covers aa extensive capacity range of 50-3,740m3/h, and is suitable for all types and sizes of vessels. The major components of the system are a backwash filter and an electrolytic cell. The self-cleaning automatic screen filter has a nominal filtration rate of 40 microns. For de-ballasting the system is bypassed and can be discharged directly overboard, after neutralisation where applicable. The system uses an active substance produced by electrolysis, to eliminate re-growth of microorganisms.
