The time, complexity and cost of a
clean-up is totally dependant on the condition of the water at the point when
you begin treatments.
A typical
example of a remediation project for eutrophied ponds - a pond with algae mats,
filamentous algae and high nutrient loading:

Biological Nutrient Removal (BNR)
Raking or harvesting of excess or floating algae mats can be done at this time. Application of Eutro-Clear Sludge
Treatment. A synergistic blend of spore-forming Bacillus strains vegetative
strains of bacteria. For areas of heavy contamination of
algae blooms and cyanobacteria in lakes, ponds and storm water run-off. For
heavy nutrient loading from non-point source contamination from agricultural
areas or heavily fertilized lawns and for lakes that are affected by leachates
from septic systems or industrial areas.
Sludge remediation combats
problems found in sludge at the bottom of ponds, lakes and rivers, particularly
sulfides, mercaptans, ammonia, fatty acids, nitrates and other sources of odor
and pollution. Especially formulated to break down feed wastes and fish manures
and waterfowl. Will break the cycle of sludge build-up, fish suffocation, algae
crashes, over-growth of weeds and cattails.

Water testing to determine nutrient
reduction rates. Applications of Eutro-Clear SB.
After stabilization of the pond, Eutro-Clear Sludge Treatment will begin the
bio-dredging process. Depending upon the initial condition of the water, this
may take several applications over several weeks. Also, at this stage
Ortho-phosphate is assimilated into cellular ATP by the competitive populations
of microorganisms. 50 billion CFU/gram product.

Ammonia reduction - Nitrification
Water testing to determine
nutrient reduction rates. Application of Nitro-Clear
. This product provides the essential nitrifying bacteria specifically
selected to bring about nitrification of ammonia nitrogen. Strains of
Nitrobacter and Nitrosomonas, with superior talent for rapid nitrification
under aerobic conditions, at a rate of 500 mg/L/Hr. Particularly where high
build-up of excess nutrients leads to proliferation of excess algae, weeds and
"cat tails". These nitrifiers consume 7.2 ppm of alkalinity for each ppm of
ammonia oxidized to nitrate. Under anaerobic conditions in the soil at the
bottom of the lake/pond the Nitrosomonas will carry out denitrification,
helping to complete the nitrogen cycle. Provided that there is sufficient
oxygen in the system, there is no danger of overdosing, even at 50 times normal
dose.

11 - Denitrification
Water testing to determine nutrient
reduction rates. Application of Eutro-Clear .
Reduces turbidity and inhibits sludge build up, improves water clarity and
algae. Eutro-Clear thoroughly cleans the water of residual feed and feces,
while participating in the natural carbon, nitrogen, phosphorus and sulphur
cycles to enhance water quality. It uses a non-pathogenic consortium of six
gram-positive spore-forming Bacillus to aggressively consume a broad spectrum
of pollutants, including surfactants, food fats and oils, sugars, starch, and
nominal amounts of pesticides and hydrocarbons, while eliminating the formation
of hydrogen sulphide and removing nitrate from the system as nitrogen gas. This
step will also address cyanobacteria and associated toxins.

Denitrification
Water testing to determine nutrient
reduction rates. Application of denitrifying bacteria. A highly concentrated
dry blend featuring denitrificans, a non-pathogenic chemolithotroph, which
simultaneously oxidizes hydrogen sulfide to sulfate or elemental sulfur and
reduces nitrate to nitrogen gas. Also included are three other gram-negative
sulfide oxidizing facultative heterotrophs and three strains of a sulfide
oxidizing, facultatively heterotrophic, gram-positive Bacillus species, to
extend the performance and application range for this product.
Selected species of denitrificans
will denitrify even in the presence of oxygen. All of the strains included in
this formula can utilize carbon dioxide as a carbon source, making this product
especially useful in systems where the carbon source has been exhausted at the
stage denitrification is desired. When targeting excess nitrate in an open
pond: While denitrification can take place in an open pond or stream, the
maximum rate will be 17 mg/L/hr.

- Phosphorous reduction
Water testing to determine nutrient
reduction rates. If additional phosphorous (SRP)
reduction is necessary, it would be done after the final denitrification. The
phosphorous is mineralized into an insoluble calcium phosphate, which
precipitate out of solution, settle and form a sediment. pH levels are slightly
elevated. This precipitate remains insoluble in pH conditions above 7.0. This
is not a "Liming" or "Alum" treatment but rather a blend of organic and
inorganic slow release oxygen compounds with a product to ortho-phosphate
reduction rate of 3:1. As the phosphorous reduction may affect the pH, any
adjustments to the pH would be done at this stage, using hydrochloric acid.
Bi-Monthly and
Monthly Maintenance
Periodic re-seeding of the microbes
will be necessary to maintain an ecologic balance and to preserve the natural
trophic conditions within the pond. Long term maintenance schedules are
determined by the ability to control point source and non-point source
contamination and associated nutrient loading. Being able to control the source
of the pollution can also assist in increasing the effectiveness of the
remediation and reduce maintenance costs.
