CWN Technology

Controlled Nano Cavitation for Recirculating Water Systems

CWN is developed for applications where water is continuously reused and recirculated throughout the system. Through controlled nano cavitation, energy is transferred directly into the water.

This physical water treatment technology supports the management of microbiological pressure, biofilm formation, and organic load within recirculating water systems, without the use of chemicals.

The technology is applied in horticulture, aquaculture, and industrial process water systems where water quality, operational reliability, and maintenance are critical factors.

Nano Cavitation in Water

How Does Nano Cavitation Work?

Nano cavitation occurs when energy is transferred into water in a controlled manner. Within the active resonator zone, microscopic vapor bubbles are formed which subsequently implode.

During this implosion, localized high energy densities and pressure differentials are released. This energy is transferred directly to the surrounding water and initiates various physical processes within the system.

In a recirculating water system, this process does not occur just once, but repeatedly each time water passes through the active cavitation zone. As a result, a continuous process of repeated exposure is created throughout the entire water system.

Nano Cavitation Process

1. High Emax Output

Maximum energy transfer to the water.

2. Energy Transfer

The CWN Pulse transfers energy to the resonator.

3. Cavitation Formation

Micro and nano cavitation bubbles are generated around the resonator.

4. Implosion

The cavitation bubbles implode and release energy into the water.

Dynamic Frequency Sweep

Water conditions are constantly changing. That is why CWN does not operate at a single fixed frequency, but uses a dynamic frequency sweep across a broad frequency spectrum.

Water conditions are constantly changing. That is why CWN does not operate at a single fixed frequency, but uses a dynamic frequency sweep across a broad frequency spectrum.

By continuously applying different frequencies, a larger portion of the water system is exposed to active cavitation. This helps maintain effective energy transfer under a wide range of operating conditions.

Various studies describe how biofilms, microorganisms, and other biological structures may respond differently to specific frequency ranges. By combining multiple frequencies, a broader operating range is achieved compared to a system operating at a single fixed frequency.

The combination of dynamic frequency control and high energy transfer is a key element of CWN technology.

Nano Cavitation in Water

Physical Processes in Water

Within the active cavitation zone, various physical processes take place. Through the formation and implosion of micro and nano cavitation bubbles, energy is transferred into the water.

As a result, several physical effects may occur, including:

  • Formation of micro and nano cavitation bubbles
  • Localized pressure fluctuations
  • High energy densities during bubble implosion
  • Intensive microscale mixing
  • Disruption of biofilm structures
  • Support of natural oxidative processes within the water system
These processes support the management of microbiological pressure, biofilm formation, and organic load within recirculating water systems.
The CWN Ecosystem

The CWN Ecosystem

CWN Pulse, resonators, sensors, and CWN Control work together as part of one integrated water treatment ecosystem.

CWN technology is developed for recirculating water systems where water passes through the active cavitation zone multiple times per day.

Depending on the application, a CWN Free is installed in a reservoir or a CWN Tube is integrated into the piping system. Sensors and CWN Control support the monitoring and optimization of the entire water system.

CWN Control

Monitoring and management through a single platform.

CWN Control is the digital layer within the CWN ecosystem. Through a single centralized platform, installations can be managed, configured, and monitored.

Depending on the installation, users may gain insight into:

  • Real time system status
  • Configuration management
  • Firmware updates
  • Performance analytics
  • Sensor integration
  • Historical data records
By combining nano cavitation with digital monitoring, greater insight is gained into the performance of the entire water system. CWN Control is continuously being expanded with new functionalities and sensor integrations.

Scientific Foundation

Nano cavitation and ultrasonic technology are widely studied around the world for applications in water treatment, biofilm control, and microbiological management. Numerous studies describe the effects of cavitation on biofilm structures, microorganisms, and physical processes within water.

CWN builds upon these scientific insights and translates them into practical applications for recirculating water systems in horticulture, aquaculture, and industrial process water installations.

The outcomes of scientific studies depend on factors such as frequency, energy density, contact time, water quality, and system design. For this reason, every CWN installation is configured according to the specific conditions of the water system.
