Restoration Of Water Quality
In Lake Weston, Orlando, Florida
Lake Weston, an 11.3-ha, 15-m deep eutrophic lake in
Orlando, Florida, was polluted primarily by effluent
from a waste treatment plant. It was treated by
CLEAN-FLO Laboratories, Inc., with aeration equipment
and a non-toxic, soluble calcium compound, to make
phosphorus unavailable for plant assimilation
The Effect of Continuous Laminar Flow Inversion,
Micro-organisms, and Calcium on Acidified Lakes
There is ever-growing concern about acidified lakes
because of acidic precipitation (acid rain and snow).
Several acids are present in the atmosphere. Carbonic
acid results when carbon dioxide from animal (and human)
respiration and the burning of fossil fuels combine with
water in the atmosphere.
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. Continuous laminar flow inversion and
buffered alum do not affect blue-green algae in any way.
Inversion, aeration and buffered
alum to improve water quality reduces nutrients
(fertilizer) needed for aquatic macrophyte (weed)
growth.
Fertilizers cause excessive growth of aquatic weeds and
algae decline as a result of nutrient reductions. All
submerged aquatic plants must absorb their major food,
carbon dioxide from the water column; not through the
roots. The CLEAN-FLO system exhausts carbon dioxide to
the atmosphere, reducing carbon dioxide to low levels.
We have considerable documentation of carbon dioxide
removal.
The Feng-Shan Reservoir Project
The Feng-Shan Water
Reservoir is a 70-hectare (173-acre), 28 m (92 ft)
maximum depth body of water located near Kaohsiung,
Taiwan. A tributary from a river that has hundreds of
pig farms upstream feeds the reservoir. The farmers dump
their pig manure directly into the river, and the
government is presently powerless to do anything about
it. The reservoir has an 11 - 17 hour retention time,
before entering the drinking water treatment plant.
Helpe Mineure River Restoration Project
Fourmies, France is a rural town of 20,000 people. It has a large textile
industry with spinning mills and cloth mills, a nut and bolt factory, glass
bottling company, computer parts factory, a seat cover manufacturer, and several
smaller industries such as restaurants, stores, bars and hotels. As the Helpe
Mineure River (Fig. 1) passes through Fourmies, COD and ammonia increase, and
oxygen decreases. Because of the water quality degradation, the water was in the
unusable category for 43 km downstream.
How Watershed Management and Continuous Laminar Flow
Inversion Reduce Phosphorus and Nitrogen in Lakes,
Rivers and Reservoirs
Watershed management is an important tool in restoring
polluted water bodies. The results, however, are often
limited and further treatment is necessary to achieve
the desired results. A major problem is that non-point
source pollution may be difficult to control. This leads
to the question, can in-situ treatment help attain the
nutrient reductions needed for limitation of aquatic
plant growth? If it can, it should become a welcome
addition to any limnologist’s tool box.
Muller Engineering Highland Lake
Sonar graphs by Virgil Muller, PE, of Muller Engineering in
Minneapolis showed an average of 4 inches muck removal per month
in Highland Lake, Anoka County. Horizontal recession of muck
from the shoreline averaged 4.7 feet in 14 months using the
CLEAN-FLO Continuous Laminar Flow Inversion / Oxygenation
System and our C-FLO living organisms.
Organic Sediment Removal
Through Multiple Inversion
Aquatic biologists and consultants have performed
numerous studies and have found organic sediment
reductions in every case. One test showed a decrease in
muck depth of 36.9 inches in one year. Our own tests on
many lakes have shown muck removed about ten feet from
the shoreline each year, leaving a clean sand and gravel
bottom, and lakes deepened 2 - 5 feet over a five-year
period.
Results of Testing CLEAN-FLO
Lake CleanserTM in Florida Lakes
This paper presents results of a pilot study of efficacy
and observable toxicity in Florida lakes of a new
product formulation compromising an admixture of soluble
calcium, aluminum and sodium cations, and a buffering
agent.
The Use of Multiple Inversion
and CLEAN-FLO Lake Cleanser in Controlling Aquatic
Plants
Prior to the use of
CLEAN-FLO Lake Cleanser in three Minnesota Lakes the
water was preconditioned to remove carbon dioxide and
bottom acids.
The Effects
of Aeration on the Shoreline Fishes of a Eutrophic
Flordia Lake
Highly eutrophic Lake
Brooker in central Florida was aerated using ceramic
microporous diffusers coupled to four one-half
horsepower air pumps.
The
influence of whole lake aeration on the limnology of a
hypereutrophic lake in central Florida
To determine the influence of a multiple inversion
aeration system upon the limnology of a small sinkhole
lake, we monitored physical-chemical and biological
parameters for 15 months prior to starting aeration and
for 24 months thereafter.
Restoration of Powai Lake
Powai Lake is a 220 hectare (540 acre) lake in Mumbai,
India. CLEAN-FLO systems were installed to improve water
quality and restore lake health. As a result the
dissolved oxygen levels increased throughout the water
column and phosphorus levels decreased by over 98%.
