Scientific test proves 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.
Because of 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 in stallation. 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 waters surface. These sound waves, operating on several frequencies, destroying 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, this 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.
