Improve Water Quality Of Potable Water Reservoirs To Eliminate
Geosmins From Blue-Green Algae, Reduce Manganese, Remove
Trihalomethane (Thm) And Eliminate Foul Taste And Water Odor Problems.
Many reservoirs around the world have water quality problems.
Water quality issues vary, but blue-green algae, manganese, trihalomethanes, taste and
water odor are at the top of the list. Trihalomethanes are cancer producers and manganese in the water
supply turns laundry grey.
Water
odor and bad taste in drinking water has plagued residents for
years. Also, a black coloration in the water often stains
residents’ clothing during laundering. Manganese, blue-green
algae, and iron all contribute to these problems. Reducing
and/or eliminating manganese, blue-green algae and iron will
solve these problems.
CLEAN-FLO International effectively solves the coloration
problem and finds a better solution to the annual algae problem.
CLEAN-FLO installs
Continuous Laminar Flow Inversion and
Oxygenation Systems in reservoirs to
improve water quality. CLEAN-FLO’s
unique aeration systems
continuously bring water up to the surface from the reservoir
bottom without creating turbulence. Turbulence would have mixed
the low-oxygen bottom water and the toxic gases that accumulate
at the bottom of the reservoirs, with the rest of the reservoir
water. Turbulence would create even worse problems than the
residents already had. Within weeks of the installation, there
are dramatic improvements in transparency, and iron and
manganese levels drop to near-zero. The taste and
water odor problems
disappear and the residents are pleased.
Our inversion system gently turns the reservoirs’ water over and
brings the foul-smelling gases up to the surface where they are
neutralized by the atmosphere. Inversion also takes oxygenated
surface water down to the bottom where the oxygen kills the
bacteria that produce the foul-smelling gases. The blue green algae, which
only grow on the surface, are taken to the bottom where it
cannot grow because of lack of sunlight. Finally, by oxygenating
the entire reservoir, iron and manganese that cause the
discoloration of the clothing and sinks, are oxidized and
deposited on the bottom. Both oxidized manganese and oxidized
iron then become useful in binding the phosphorus and nitrogen
to the bottom sediment, making it no longer available for algal
growth.
CLEAN-FLO aeration systems sometimes adds natural buffered phosphate precipitants
and natural, harmless beneficial bacteria that feed on dead tree
leaves and wastes that wash into reservoirs when it rains. The
precipitants and the bacteria both remove food for aquatic
plants and algae. The inversion of reservoirs is so effective
that phosphate precipitants and bacteria additions often are not
necessary. The inversion process is more effective than ordinary
aeration systems. It is less costly than treating all incoming
water from the watershed, which is impossible, anyway. Most
incoming water, such as "non-point source" watershed runoff
cannot be treated at all before it enters the reservoirs.
Our experience with reservoirs since 1970 has shown that
utilizing the CLEAN-FLO aeration process on reservoirs results in a
significantly reduced cost of water treatment.
The Feng-Shan Reservoir Project: Taste and odor problems from
the Feng-Shan Reservoir in Taiwan were caused by manure from
hundreds of pig farms upstream. CLEAN-FLO quickly eliminated the
taste and odor problem and saved the Taiwan government $586,000
a year in water-treatment costs.
Cyanophyceae in reservoirs and lakes: Cyanophyceae
(blue-green algae) in reservoirs are a primary cause of
unfavorable taste and odor in drinking water. This paper
presents a history of studies showing less blue-green algae in
lakes and reservoirs using combinations of continuous laminar
flow inversion and buffered alum.

Taste and odor problems are eliminated with the use of CLEAN-FLO
inversion systems.
