Less is more.

Making it simple for you.

It goes without saying that the ideal product is one that can do not only ‘this’ but also ‘that’ as well...

To all you shipowners, we know it can be difficult to find the motivation to go through all the effort of researching ballast water treatment systems yourselves.

Thankfully, Muira’s HK system offers 7 major advantages that help you cut down on tiresome extra work.
Our goal is to reduce the time and hassle for shipowners, managers, crew and management companies.
Our philosophy is “Less is more.”
Looking beyond the categories of cost, time, and labor, Miura takes a comprehensive approach, reducing and omitting extraneous tasks wherever possible. Here we introduce the 7 ways in which we accomplish this.

The environment-friendly elimination method

photo:Filter + UV Harmless

Miura’s large size filters, with pores larger than 50 μm, eliminate 99.99% of organisms, while our small-size filters with pores smaller than 50 μm reliably kill off all other organisms using UV irradiation. UV irradiation completely eliminates organisms in an extremely clean process that is not harmful to the environment.



Smart filters eliminate the need for tiresome cleaning


Flow charts can be displayed using the touch panel, making it easy to keep track of filter operating status. Even navigation officers with little experience or untrained staff can easily clean the filters with the touch of a button. Moreover, the filters can be cleaned without opening the filter cover. As operation is possible even from outside the engine room, it is easy to send out a warning or announcement if needed. Preventative operation is made simple, and safe operation effortless.

Our capable supervisors can handle any kind of retrofit

Retrofitting requires the cooperation of someone with the imagination to visualize a range of possibilities, a detailed plan for installing equipment in a limited space, and a wealth of experience. At Miura, our team of expert supervisors and engineers provide support during every step of the retrofitting process, from vessel inspection to 3D scanning, design, and equipment installation. We have equipment suitable for vessels of all types and sizes, and for various installation environments. It is highly unusual for us to come across a vessel we cannot outfit.
