The Mezzo can be used in ponds as large as 5 acres, depending on the algae type that you're dealing with. For thicker, filamentous type algae, around 2 acres of coverage could be expected. Less dense single-cell algae allows for great range of coverage.
The Mezzo Ultrasound System includes the sonic head and power module, and float. A water-proof power cable is also required and can be customized for lengths up to 200 meters (contact us if you require a longer cable run). Select the best length above to suit your application.
The Mezzo is bi-directional which provides 180 degrees of coverage from the device and it uses dual bandwidths for greater frequency density. These are both features not found before in ultrasonic devices. The bi-directional sound output is achieved with just one piezo sound emitter that operates in two different bandwidths for better control of green algae and diatoms in the lower bandwidth and blue-green algae in the higher bandwidth.
The device works in harmony with aquatic wildlife (fish and animals), aquatic plants, bio-solids and planktonic organisms other than algae. Since the device can control biofilm formation on cleaned surfaces, you may notice surfaces near the device remain clean for long periods after being initially cleaned. This is due to inhibiting anaerobic bacterial colonization due to their sensing the ultrasonic signature as water turbulence. Fungi (e.g. Pythium) and bacteria with gas vesicles will also be controlled by the device by causing them to lose buoyancy.
The device creates ultrasonic frequencies that cover two important bandwidth areas where algae can be controlled via critical structural resonance similar to the way a crystal glass can be broken by the right sound pitch. Ultrasound works as the force to cause these internal vibrations in algae cells or in organelles inside the algae cells that disable them. The system is powered via the power module that is available for use with many types of power input including solar.

The Mezzo Ultrasonic System is made up of three main components. These are the ultrasonic head, the power module/controller, and the power cable. A float is also included in the package however it may be optional to use this in some settings.
This contains the frequency driver and the sonic emitter that produce the ultrasonic output signal. The top section house’s the piezo sonic emitter between two metal plates so the sound is projected away in 2 directions. The base contains the needed circuitry to power the piezo operation. The two way output is unique in the industry.
This can be AC or DC electrical in- put. AC inputs include 24, 100/120 and 240 volt service at 50 or 60 Hz. DC input is 24 volts via solar or AC charged batteries (typically two 12 volt batteries in series.) The power module converts the input power to the 44 volt DC line voltage need- ed to power the sonic head. The power supply will power two separate sonic heads for added economy.
This connects the power module with the sonic head to provide power and communications to and from the sonic head. The cable can come in any length up to 500 meters (about 1640 feet). Other devices of this type are typically limited to cables lengths of 75 meters due to cable voltage drop that reduces the incoming voltage and causes the sound output level to drop proportionately. The Mezzo has compensating circuitry in the sonic head to restore any voltage drop in the cable run so that it always runs at full strength and is a patent pending feature of the device.
*Effective control range will vary by the algae type. String or filamentous algae will reduce the range somewhat compared to the less dense single cell algae.
