Ultrasonic
Algae Control System - Up to 32' x 16'
These ultra sonic algae control systems
are a great way to easily control algae in water features and ponds up
to 3 acres in size, and Prevents bio-film and other pathogens
such as E.Coli.
How it works:
In most basic terms, the algae cells get shaken to bits! In little more
detailed terms, the control box of the Ultrasound system has a micro
chip that digitally generates a range of ultrasound frequencies. The
transducer (under the water) then emits these frequencies as a series
of pulses five times per second. As these pulses strike the algae cells
they start to oscillate. The cells reach a point where they burst, much
like an opera singer smashing a wine glass on the right note!
Not only will ultrasound kill algae but it also
eliminates“biofilm”. This is the slime that can be
found on submerged surfaces (ie. rocks, liner, etc.). Over time algae
grows on the biofilm. Ultrasound waves prevent biofilm as well as other
water born pathogens such as E.coli.
Works In All Seasons!
Some strains of algae grow during the winter months. The Ultra Sonic
works in all temperatures and is helpful in preventing spring time
algae blooms that often occur when the ice melts.
The ultrasound waves emitted are absorbed as they travel through the
water. In essence, they become weaker the further way they travel from
the transducer. As a result, easy to control algae types can be
controlled far out into the pond while harder to control strains, like
Chara, will be controlled in close ranges but not as far away. See the
charts at left for approximate coverage areas for various strains of
algae. While the initial purchase price is higher than chemicals for
controlling algae, the increasing cost of these products along with
many new paperwork regulations coming make these units a great control
method. Divide the cost of an ultrasound unit by ten (average life span
in years) and the cost per year is very comparable to chemical algae
control, its better for the environment and you install it, plug it in
and your done - no maintenance!
It is important that the transducer is located in the proper location
of the pond. Islands, bays and other obstacles in the pond will limit
the effectiveness of the unit.
Coverage Area:
The size of coverage area will depend on several factors including the
type of algae being controlled. Simple algae forms like floating algae
will be controlled over an area up to the sizes listed above, harder
forms of algae will be controlled over a smaller area due to their
resistant nature. Other factors such as pond shape, presence of
fountains/aerators, water clarity, weed growth, etc will also affect
coverage size. In larger ponds having complex shapes more than one
device may have to be used.
A
minimum of 2 1/2' of water depth is required for any Ultra Sonic system
to work properly.
