BWMS completes USCG tests

Evoqua's SeaCURE system Evoqua's SeaCURE system has now completed all USCG type approval tests

US operators could benefit from an electrochlorination-based BWMS system which has completed tests needed for US Coast Guard approval.

Evoqua Water Technologies’ SeaCURE BWMS underwent biological efficacy USCG type approval tests carried out by independent laboratory NSF International.

Matt Granitto, business manager - SeaCURE at Evoqua Water Technologies, said: “It has been a lengthy process but the importance of these tests and USCG Type Approval cannot be undervalued.

“The testing regime we opted for was the most stringent because it uses natural organisms in natural environments over those that are manufactured. By using real organisms, it takes a lot longer as nature doesn’t always have sufficiently high organism counts.”

NSF International will now compile test data for USCG approval.

One unit of the SeaCURE system is capable of treating up to 6,000m3/h from a skid of 2m x 1.5m.

The first five tests in brackish waters took place in Baltimore Inner Harbour in 2015, overseen by NSF partner Maritime Environmental Resource Centre (MERC).

Great Ships Initiative (GSI) subsequently carried out five freshwater tests in 2016, with the final set of land-based tests completed this year by Holland’s MEA-NL, in conjunction with classification society Lloyd’s Register.

Shipboard testing was also conducted in various global locations with scientists from MERC.

Evoqua anticipates receiving USCG BWMS type approval before the end of the year.
