Scientific tests prove the impressive
performance of the
Waterman Algae Controller
|
Scientific tests performed on a man-made lake at the Western
Australian Police Academy by the West Australian Department of
Environment have provided a clear indication of the effectiveness of
the Waterman Algae Controller.
Due to its central location inside the Academy grounds, the
appearance of the man-made lake is of prime importance to the Police
Academy.

As a result of re-occurring algal blooms in summer, the
Academy purchased three Waterman Ultra Sonic Algae Controllers to cover
the entire lake area.
In order to provide the academy with scientific proof that the
units were performing as intended, water samples were taken prior to
and 50 days after installation. The full reports,
provided with the approval of the Building Management Authority of
Western Australia can be provided upon request.
The results of this test, that showed a remarkable 98%
reduction in algae concentration, is shown
in a table below:

As can be seen from the above tables there has been a
substantial reduction in the amount of algae in the water. The
predominant Tabularia alga had all but disappeared in the second test.

How does it work?
The Waterman Algae Controller works by transmitting highly
targeted ultra-sonic sound waves below the water surface. These sound
waves, operating on several frequencies, destroy the vacuole within the
algae. The principle is similar to the phenomenon of an opera singer
shattering glass when they reach a certain note. The vacuole in algal
blooms plays a role in phagocytosis (cellular digestion), disposing of
cellular waste and regulating osmotic (water) pressure within the cell,
maintaining its structural integrity. The Waterman Algae Controller
ruptures the tonoplast (thin membrane) which protects the vacuole,
which results in the alga cell no longer being able to: 1)regulate
osmotic (water) pressure 2) dispose of wastes and toxins 3) grow and 4)
obtain nutrients.
Effectively, once the vacuole has been destroyed, the algae
are killed and your lake is clear.
