LAKE & DAM
REMEDIATION WITH OZONE AERATION SYSTEMS
Most of the natural and man-made lakes and dams are subject
to the gradual accumulation of organic waste material at the bottom. Logs,
dead animals, storm washouts and other materials settle at the bottom and
build up a graveyard of unhealthy mass which is characterised by its total
lack of oxygen, and consequent support of anaerobic pathogenic life. This
accumulation progresses to the point where the whole lake dies. The dirty
constitution and resulting odour makes such water unattractive and useless
for aquatic life, recreational purposes, and especially as a drinking
The natural solution to this problem is to
be found in enhancing the oxygen levels in such lake. For this purpose
special, laser-cut hoses are engineered to float at the top of the
anaerobic mud located at the bottom of the lake. With a relatively small
compressor assisted with ozone for automatic self-cleaning from inside the
diffusing hoses, even a large and very sick lake can be restored to full
aerobic health in just about ten weeks. In addition, the hoses slowly eat
through the already accumulated organic waste at the rate of approximately
6" (15 cm) per year until the bottom is clear. The system also hinders any
new accumulation of waste.
As a result of the remediation, aquatic life is restored, and the water
becomes very clean and suitable for recreational purposes. Dissolved
organic content may also drop from the typical 5 to 20 mg/L down to below
1 mg/L. Logically, if the lake is used to supply drinking water, the
treatment station downstream requires much less ozone to finish the
purification process and sanitize the water flow completely from all
viruses, bacteria, mould and parasites.
Though this technology has been around for many decades it is not yet well
known for the simple fact that it is too inexpensive and thus not
as attractive to lake remediation equipment suppliers.
ECO-TEC can provide very specific and
inexpensive solutions to your particular water problem.
