Germany-based Peter Döhle Schiffahrts-KG has signed an agreement with Erma First for the supply and installation of ballast water treatment systems (BWTS) onboard its entire fleet of vessels.

Peter Döhle Schiffahrts-KG’s existing fleet includes vessels of different sizes and types, including bulk carriers, container vessels and others.

Erma First managing director Konstantinos Stampedakis said: “Our aim is to provide a full service package that includes regulation compliance, low capital costs, system operation simplicity, low energy requirements and a vast after-sales support network, in order to make sure that both parties remain satisfied and our mutual benefits are met.”

Erma First’s BWTS FIT range of BWTS system had previously received type approval from the United States Coast Guard (USCG) and the International Maritime Organization (IMO) for use in almost all types of water.

“The systems are designed for both small and large ballast-pump capacities.”

The systems are designed for both small and large ballast-pump capacities. They offer negligent environmental footprint and require reduced power to operate.

During the process of ballasting, water goes through the BWTS filter, where organisms and sediment are separated and further discharged overboard the vessel.

The filtered water enters the Electrolytic Cell to produce free chlorine from the chlorides of the water, using electrolysis process at a very low concentration of around 4mg/L-6mg/L.

The treated water then moves in to the ballast tanks. Throughout de-ballasting, the BWTS system will only track the residual oxidants and will further intervene if required.

In May this year, Erma First received a contract from Oldendorff Carriers to provide its BWTS system.
