Optimarin offers state of the art Ballast Water Treatment System – compliant with both IMO and USCG regulations.

24 years of experience using filter and UV to treat ballast water in a way that is friendly for the environment.

Simple, effective, reliable

Optimarin ballast water treatment system combines simplicity with innovation. We utilize a combination of automatic back flushing, self-cleaning filters and powerful UV irradiation to neutralize all potentially invasive species in the water.

With a modular nature, the system is flexible and easy to install on any vessel (newbuild and retrofit). Even those with the most restrictive space demands. Our solution does not use nor generate chemicals in its process. Most importantly: It is simple to operate and maintain.

Whatever your vessel, whatever your operations, whatever your individual requirements – Optimarin has the experience and technology your business demands.

Dedicated to Ballast Water Treatment, dedicated to you

No one knows ballast water like Optimarin. We were the first ever company to install a commercial ballast water treatment system, in 2000 on-board the Princess Regal, and have been refining our technology ever since.
We are committed to supplying systems that protect both the environment and the commercial interests of our customers. We know this industry and we understand your needs.

    “Our experience is that Optimarin Ballast System is well engineered product of good quality. It is simple and relatively compact. The system was ordered and delivered as loose components what makes the installation easier, in particular on smaller vessels where limited free space is available.”
