The Quattro-DB can be used in ponds and lakes as large as 120 acres (or more with multiple units), depending on the algae type that you're dealing with. For thicker, filamentous type algae, around 17 acres of coverage could be expected. Less dense single-cell algae allows for greater range of coverage.
The Quattro-DB 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 500 meters (contact us if you require an extended cable). Select the best length above to suit your application. Solar power options are also available..contact us for more information on those power options.
The Quattro-DB is omni-directional, which provides 360 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 omni-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 Quattro-DB Ultrasonic System is made up of three main components. These are the ultrasonic head, the power module/controller, and the power cable. A float and attachments are also included.
This contains the frequency driver and the sonic emitters that produce the ultrasonic output signal. The top and bottom sections house the piezo sonic emitters. They are offset by 90 degrees so that the sound is projected radially away in 4 directions. The two way output and the two piezo mounts are unique in the industry.
This can be AC or DC electrical input. 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 40 volt DC line voltage needed to power the sonic head.
This connects the power module with the sonic head. This provides power and communications to and from the sonic head. The standard cable length is 150 meters (about 500 feet) but lengths up to 500 meters (about 1640 feet) are possible. Other devices of this type are typically limited to cables lengths of 75 meters due to cable voltage drop reduces the driving voltage for the circuit and the sound output level drops proportionately. The *Quattro-DBTM has compensating circuitry in the sonic head that boosts the incoming voltage to the 40 volts needed by the circuitry and is a unique and patent pending feature of the device.
This provides buoyancy for the sonic head and cable. The placement of the device is normally away from the bank so that there is a line of sight from the device to as much of the shoreline as possible. A flag on the float warns boaters not to anchor there due to the cable below. The user supplies an anchor to which the unit is tethered. The cable runs back to shore to a power supply run on AC or DC power.
*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.
