The Mezzo Ultrasound System retails for $1995.00 for 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 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 - 3 acres of coverage could be expected. Less dense single-cell algae allows for great range of coverage.
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.
Sonic Head:
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.
Power Module:
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.
Connecting Cable:
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.
