How Ultrasound Works on Algae(the mini explanation)

Unit produces 2000+ varying Frequencies sent out into the water column

Different frequencies affect different algae types (genus)

Blue-Green algae - Rupture Gas vacuoles / vesicles

Green Algae - Break cell wall bond

Interferes with Reproductive Cycle

Expedited algae cell death


Spirogyra – Before and after. 3 Weeks of ultrasound treatment


Gas VacuolesWon’t break cell wall

Untreated Cells Treated Cells for 24 Hours

Gas Vesicles ReleaseGas to Outer Cell Wall

Outer Wall is Permeable to Gas

Toxin Release Concerns – Eliminated

Ultrasound does not allow for lysing of the cell

Ultrasound stops the cell growth & Does not break outside wall

Cells disabled – can no longer generate nor release toxins



Effects Of Ultrasound On Green AlgaeCentre for Aquatic Plant Management, UK Work

The picture on the left shows healthy Spirogyra, with cells full of cytoplasm, and the characteristic spiraling chloroplasts. The algae was sourced from a tank at the CAPM in Sonning and had been healthy for at least 5 years.

This picture was taken after only 7 days exposure to ultrasound. Already the plasmalemma is coming away from the cell wall, and the cells have shrunk. There is increased granulation of the cytoplasm, indicating loss of chloroplast structure, and loss of connectivity with other cells and the external environment.


Effects Of Ultrasound On Algae

• Causes green algae to die in 3-4 weeks by internal cell fluid disruption. Range 150 meters radially or 17.5 acres.

• Causes blue-green algae with gas vesicles to settle to the bottom in 3-4 days due to loss of buoyancy. Must die out of light. Range 400 meters radially or 120 acres.

• Causes anaerobic bacteria to sense false water turbulence disrupting their growth and colonization. Range 60 meters radially or 2.8 acres. (Biofilm prevention)

Some algae not controlled with ultrasound


Pithophora Chara Nitella

HydrodictyonIf it looks like a plant, it is unlikely that ultrasound will harm it.


More types of Algae Not Controlled With Ultrasound

Euglena

PediastrumTypes

Oscillatoria

Cylindrospermopsis Raciborskii

Who can use ultrasound technology?

Large Lakes & Reservoirs

Private and recreation ponds

Golf courses

Wineries

Municipalities – WWTP, Water Facilities, Lagoons

HOA

Storm Retention Ponds

Koi ponds and other aquaculture


Sterling Vineyards, CA

Why use Ultrasound Technology?

Eco-friendly

No permitting required

No generation of By-products

No genetic mutation of survivors.

Simple to install and little maintenance

Inexpensive to run (less than 50 watts of power)

Reduces chemical usage

Targets only algae

Large bodies of water are not a problem

Wall biofilm where significant quantities ofbacteria are produced can be significantlyreduced or eliminated.


Hegins, PA


Disdvantages of Ultrasonic Algae and Biofilm Control Macrophytic or plantlike algae are more difficult to eliminate or are

unaffected.

Thick plants or these plantlike macrophytic algae structures can prevent ultrasound vibration to reach other parts of the water to be treated

A “line of sight” to the algae must be available for the transducer output to be effective.

A few algae types will not be affected by ultrasound (some euglenoids, oscillatoria, some scendesmus, macrophytic, and some colonical types like pediastrum are resistant).

Patience is required as weeks are sometimes needed for full effectiveness on algae.

Precleaning surfaces is necessary for the greatest biofilm prevention benefit.

Things to keep in mind

Takes time to work!! Patience is key

Blue-Green algae – can see results in a few days

Green algae – 3 weeks – 3 months depending on the algae

Bloom-Kill Cycle

Ultrasound cannot control outside factors

Nutrient Loading

Weather / natural and environmental influences

Case StudyAlgae Control without Chemicals

For UTILITIES

• At the Attala Plant, seasonal issues occur with Blue-Green Algae (Cyanobacteria) growth in our source water.

• Big Black River > 60 Day Pond > 7 Day Pond > Clarifier > Raw Water Storage/RO feed > CT/Demin Tank

• Previously we have not been able to apply traditional treatment methods to control the algae growth and it is getting worse ever year.

• This begins to grow in the 60 day pond where the nutrients from the agricultural run-off are consumed.

• The algae rapidly grows in the shallow water of the 7 day pond where the optimal conditions exist for proliferation.

Blue-Green Algae IdentifiedBlue-Green Algae Identified

• A sample was sent to Mississippi State University to perform a toxicity study and it was determined that our bacteria was non-toxic

• The species of Cyanobacteria contained in the Entergy water source was identified as Microcystis

• Several species of Microcystis release a Neurotoxin

Issues caused by Blue-Green Algae at Attala plantIssues caused by Blue-Green Algae at Attala plant

• Small, weak, light flocculation• Clogged sand filters• Biological fouling of RO membranes and

heat exchangers• Excessive chemical consumption in the

cooling tower to treat the increase biologicals

• Excessive cost to treat incoming raw water for plant use.

InstallationInstallation

On 2/13/2017, an Ultra-Sonic sound wave device was installed and put in service.

The SS-600 ultrasound unit (now discontinued) was installed on the north bank of the pond directed south for optimal coverage.

Pond Size: approx. 11 acres


Initial TrialInitial Trial

A 90 day trial had begun and the results became apparent after the first month. A small algae bloom had developed and the dead algae was noted floating on the surface.


Conclusion of 90-Day Trial / Case StudyConclusion of 90-Day Trial / Case Study

Results:• Decreased TOC in water

treatment plant inlet water• Decreased labor in Clarifier

operations• Decreased chemical

consumption• Decreased Maintenance in

Raw Water Supporting Systems

• Substantial financial savings


Proven to be effectiveProven to be effective

This device is proven to be effective for a low cost treatment of Blue-Green Algae and Green Algae in surface water.


Case StudyUltrasound for Algae Control Drinking Water Reservoir

Wilmington, OH


• Historically had Green AND Blue-Green Algae in both Reservoir 1 and Reservoir 2

• Cylindrospermopsin & Microcystis were main Blue-Green algae concern

• Past algae remediation included copper sulphate treatments

• Copper Treatments were labor intensive and expensive

• 2018 Goal: Reduce chemical usage, costs and labor

• TRIAL: Treat Reservoir 1 with Quattro-DB (SolaRaft) and use Reservoir 2 as a control continue to treat with Copper Sulphate

Background – Reservoirs 1 & 2 – Wilmington, OHBackground – Reservoirs 1 & 2 – Wilmington, OH


A Sound SolutionA Sound Solution

• In May 2018, a SolaRaft™ unit was installed in Reservoir 1 to begin A 90-day Trial

• Reservoir 1 is approximately 14 Acres

• Reservoir 2 is approximately 50 Acres

• Algae Testing was performed by the Ohio EPA (nutrient load and other factors were not addressed in this trial)

Report from Rick Schaefer on 7/11/18:“We were extremely happy with the performance of the unit until Friday when we received test results from EPA indicating a low level of the algal toxin cylindrospermopsin in the reservoir…The reservoir with the ultrasonic unit is certainly clearer than it has been historically, and it has an overall lower cyanobacteria count. It could be that it’s just less effective on the benthic species.

Last year’s cylindrospermopsin level peaked at 1.0 ug/l in September, about seven times higher than the result found last week. At this point, I’m hopeful that the unit keeps it from getting that high.”


Case StudyBiofilm Prevention & Algae Control

in WTP BasinsSearcy, AR


Short SummaryShort Summary

Both sedimentation basins have the same source water and identical run times on them. It is notable the SonicSolutions treatment does have a visual improvement compared to the control basin #3 with no treatment. Less algae buildup and less media surface blockage.

Where Installed: Basin Chain When: 2017

Goal: Biofilm prevention

Problem Solved! “The technology is too titillating to ignore. We were confident enough in noting less buildup with summer algae on basin walls (we are using comparative controls) that we purchased two units after the trial period. We are extending out testing. So far the results are positive and we are looking at a future purchase of more units outfitting all our water treatment sedimentation basins."
