Science from Bergen, built for the world's water

NanoMAR AS is a water-technology company in Bergen, Norway, founded in 2023. We build nanobubble systems that treat water with physics rather than chemistry — patented equipment that dissolves oxygen, air or ozone into water as bubbles under 200 nm, and that removes contaminants without anything being dosed.

The company exists because two halves of the problem had to meet. The science of sub-micron bubbles was well established in the literature and well understood in the laboratory. The equipment that would put that science to work in a fish farm at three in the morning, in a treatment plant with a rising load, or on a process line that cannot stop, largely was not. NanoMAR is the engineering that closes that gap.

We are a small, technical company and we sell to technical people. That shapes what you will find on this site: specifications rather than adjectives, articles on nanobubble technology written by the engineers who build the equipment, and an explicit account of what we do not yet know about your water.

The technology came out of water-purification research at the University of Bergen, and the relationship with academic work has not stopped being useful. The behaviour this equipment depends on — stability of sub-micron bubbles, zeta potential at the gas–liquid interface, enhanced mass transfer — is established in the published literature rather than proprietary to any supplier.

What is proprietary is the engineering: how the bubbles are generated, how consistently, at what energy cost, and how the machine behaves in the water it will actually see. That is the part that has to be demonstrated rather than cited, which is why NanoMAR sells a portable laboratory unit and a pilot-scale platform as products in their own right. A supplier who will only sell you a production system is asking you to take the important part on faith.

If you are running your own trials, we would rather help you design the measurement than send you a brochure. How that works in practice is on the pilots and validation page.

The generation technology is patented. Beyond that, here is what we will and will not put in writing, because the distinction matters more than it might seem.

What we publish: the platform performance figures — 80 %+ removal of suspended matter, 50 %+ turbidity reduction, 40 %+ higher oxygen transfer, and zero chemicals added — along with the full specification of each of the five models. Those figures describe the platform, and we state them as minimums.

What we do not publish: prices, delivery times, energy-saving percentages, and any result attributed to a named customer or site. Not because they are unflattering, but because a number without its operating conditions is not information. An energy figure depends on your alpha factor, temperature, tank geometry and the state of your existing diffusers; quoting one without those is a sales device.

Datasheets are issued with a quotation, written against your flow, your gas and your water chemistry. If a supplier hands you a performance figure with no conditions attached, ask what conditions it was measured under — including when that supplier is us.
