oneTANK How-To

ERMA FIRST, the global BWTS leader, is bringing the world’s smallest and easiest to install ballast water treatment system to the international market through its acquisition of US firm oneTANK LLC, a subsidiary of US naval architecture and marine engineering firm Glosten.
oneTANK is a small scale innovative, low-cost, IMO Revised G8 Code and United States Coast Guard compliant system. Also, its mixing technology is developed and patented by U.S. Geological Survey.
The oneTANK system is a game-changer for smaller vessels struggling to comply with stringent ballast water regulations.
It is a simple, low cost and fully automated offering. This makes it ideal for smaller vessels that don’t ballast regularly and often have space restrictions, such as workboats, tugboats, fishing boats and superyachts as well as semi-subs and tanker aftpeak tanks. The fitting is fast, flexible and economical.
ONE ENVIRONMENT IN MIND
oneTANK has been tested to demonstrate removal of viable aquatic invasive species, it also ensures that residual chemical levels are environmentally friendly.
The technology has undertaken significant testing for disinfection by-products in accordance with guidance from the International Maritime Organization.
A small, simple system is also a sustainable system. oneTANK uses no exotic materials, no filtration, no transformers or rectifiers. At the end of its life, the system is fully recyclable.
