How it works

A perfect solution for all your problems with scaling, corrosion, biofouling and barnacles offers the unique Merus technology. This technology, which basically consists of a ring that is installed around the pipes in question, gives off molecular oscillations disturbing the lime scale, rust, bacteria, algae etc. in your fresh- or seawater lines and applications. Afterwards, the substances are flushed away leaving water lines and applications mostly free of harmful build-up and bringing them back to high performance levels.

The same counts for hydro carbon lines and applications, where paraffin wax, biofouling and corrosion often causes efficiency drop-down due to blockage or leakage.

A perfect solution for improving the efficiency of:
– heat exchangers, cooling loops, cooling towers, cooling water treatment, seawater evaporators, (steam) boilers, calorifiers, reverse osmosis systems, all kind of seawater applications, separators, hydrophores, pumps, etc.

The very basics of how Merus emits oscillations
The Merus ring is made out of two halves of a treated alloy. The two halves can easily be installed on the outside of a pipe as a collar. Once the Merus ring is installed, it automatically starts to emit different kind of oscillations. For each problem there is a dedicated oscillation to fight a specific problem.

One oscillation fights rust and corrosion, one fights calcium scaling and other salts and one is fighting microbiological problems such as bacteria, algae or biofouling. Finally, the Merus ring is also applicable for problems with hydrocarbons.

Changing oscillations

Water has the ability to take a certain amount of external particles. When this amount is exceeded, these particles will settle and there is a high chance of hard crust formation. A very frequent consequence of this result is lime scale, which causes all types of problems for several industries. One of the reasons why the particles settle together, is the way how the atoms of water and lime scale move around or oscillate. When these movements change, the solubility of these external particles in the fluid will increase.

Normally, the atoms move synchronously, which means that every single atom oscillates the exact way as any other atom. If another oscillation gets involved in this movement, there is a large chance that these two will overlap, which is called interference. This basically means that two different oscillations are combined to one new oscillation. When an oscillation reaches the fluid, it is called active oscillation.

To let the oscillation reach the fluid, a carrier is needed which can transmit it and also maintain the oscillation. That is why the Merus ring was developed, to function as this carrier. This ring has to be installed around the pipe, without any contact with the fluid. The oscillations are namely transmitted into the fluid through the pipe.

In order to illustrate this process, a comparison can be made to how music is transmitted through the air by acoustic waves. One is able to hear sounds coming from a loudspeaker without having to touch it. With the right amount of volume, it is even possible to listen to music coming from another room, through the wall. This is the exact same performance of the Merus ring, which transmits waves or oscillations to the fluid to enable it to move in a specific way.

In addition, even interference is a phenomenon which can be compared to listening to music. In order to reduce noise and enhance the music sound, a concept called “anti-sound” is used. So even for music, the combination of two sounds can result in total silence.

Superimposing oscillations - Basics

In this graph, natural and active oscillation have the same frequency, yet the contrary scales. They are overlaying each other and therefore cancelling each other out, which is why the resulting oscillation can be found on the x-axis.

Merus oscillations graph

In this graph,  the peaks and valleys of the natural and active oscillation are occurring at the same time. For this reason, both oscillations are strengthening each other. To conclude, the resulting combined oscillation has a higher peak than the original oscillations.
