Biofilm Prevention With Ultrasound

We build renewed ultrasonic hardware that eliminates biofilm. Our ultrasonic systems empower organizations and individuals to effectively protect their boats, pipelines, and water installations.


Na anderhalf jaar intensief samenwerken hebben wij, dat wil zeggen Wim en Pieter-Jan Voss enerzijds, en Nick De Vos anderzijds, besloten elk onze eigen weg te vervolgen.

Wij blijven allen actief in de sector van de ultrasone technologie, maar een andere bedrijfsvisie noopt ons ertoe voortaan verschillende accenten te leggen.

Wim en Pieter-Jan zullen de vennootschap verder leiden onder de vernieuwde handelsnaam ‘Ultrasonic Group’ ( ). Zij zijn voortaan te bereiken via en

Creating state-of-the-art products that combat biofilm

Biofilms are microbiological layers in which  algae, bacteria, limescale, corrosion, and other pathogens can grow. They thrive on moist or wet surfaces, making them the perfect breeding ground for more bacteria and micro-organisms to develop. This leads to critical damages and creates an unhealthy environment for humans and animals.

NDV Ultrasonic combats biofilm in a chemical-free and non-toxic way, making it the most efficient, cost-saving and ecological way of cleaning all water systems.


By eliminating biofilm with NDV Ultrasonic, the growth of algae, bacteria, and limescale is prevented. This creates a safer environment for the system and its users.


Our devices are non-toxic, chemical-free and require a low power supply. By using NDV Ultrasonic you reduce fuel emissions and carbon footprint, while sustaining a healthy environment for both humans and animals.


Not only does NDV Ultrasonic guarantee a longer lifespan of all systems, our products also reduce energy and maintenance costs and ensures a reduction in the use of chemicals.


NDV Ultrasonic devices operate on any system working with water or any other liquid (such as fuel, alcohol, milk, etc).

I would recommend NDV Ultrasonic to everyone with a sailboat. It saves me on yearly maintenance costs in a eco-friendly matter.

Fishing Pond
I had a lot of issues with thread algae in my pond but after one month with NDV Ultrasonic, I could easily scoop out the algae and could finally see the bottom. After 6 years, I never experienced any problems anymore.

Swimming Pool
I had a slight bit of ‘green’ on some of the floor/walls of my pool. This now seems to have gone, forever.

With NDV Ultrasonic, my antifouling has been there for 5 years straight, and the boat is still clean without being replaced or taken out of the water!
Francis C.
The device installs quick. Now I don't have to clean my jacuzzi every two months and can leave it as it is without adding any chemicals to it.
Léon D.
I had a fully personalised service for my swimming pond. A fantastic product with great results, and it doesn't harm my fish but actually creates a better environment for them!
