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. www.SonicSolutionsLLC.com 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.

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 Hegins, PA Wall biofilm where significant quantities of bacteria are produced can be significantly reduced or eliminated. www.SonicSolutionsLLC.com 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. www.SonicSolutionsLLC.com 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 “Tool in the Toolbox” www.SonicSolutionsLLC.com Time Lapse Results Using Quattro-DB ® Unit Private pond in Iowa Start Day 14 Day 21 Day 28 Filamentous algae take about 3-4 weeks to fully die from ultrasonic damage. www.SonicSolutionsLLC.com Drone Photo of Quattro-DB ® Unit – Ohio www.SonicSolutionsLLC.com Solar Powered Quattro-DB ® Application: DowDupont River Works, Orange TX www.SonicSolutionsLLC.com Quattro-DB ® Applications: Floating Solar unit in Drinking Water Reservoir, Putnam Lake, CT Aquarion Water Company of CT www.SonicSolutionsLLC.com Case Study Algae Control without Chemicals For UTILITIES Presented by Devon Assael, VP Sales & Marketing SonicSolutions, LLC [email protected] Cell: 413.887.4544 Prepared with Jared Berry, Mississippi Chemistry Specialist, Entergy Background – Entergy, Attala Plant • 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. www.SonicSolutionsLLC.com Blue-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 29 www.SonicSolutionsLLC.com 1 Issues 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. 30 www.SonicSolutionsLLC.com Installation 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 www.SonicSolutionsLLC.com 1 Initial 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. www.SonicSolutionsLLC.com Conclusion 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 www.SonicSolutionsLLC.com Proven 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. www.SonicSolutionsLLC.com Case Study Ultrasound for Algae Control Drinking Water Reservoir Wilmington, OH www.SonicSolutionsLLC.com Background – Reservoirs 1 & 2 – Wilmington, OH • Historically had Green

  • €˜Shameless’ Thanks Fans for Season 9 Return
    ‘Shameless’ Thanks Fans for Season 9 Return 06.07.2018 Shameless star Emmy Rossum and other cast members thank fans for their love and support in Showtime's teaser announcing a ninth season of the series. The promo features a nostalgic montage that looks back at key moments from the show. When it returns, political fervor hits the South Side and the Gallaghers take justice into their own hands. Frank (William H. Macy) sees financial opportunity in campaigning and gives voice to the underrepresented South Side working man. Fiona (Rossum) tries to build on her success with her apartment building and takes an expensive gamble hoping to catapult herself into the upper echelon. Meanwhile, Lip (Jeremy Allen White) distracts himself from the challenges of sobriety by taking in Eddie's niece, Xan (Scarlet Spencer). Ian (Cameron Monaghan) faces the consequences of his crimes as the Gay Jesus movement takes a destructive turn. Debbie (Emma Kenney) fights for equal pay and combats harassment; and her efforts lead her to an unexpected realization. Carl (Ethan Cutkosky) sets his sights on West Point and prepares himself for cadet life. Liam (Christian Isaiah) must develop a new skillset to survive outside of his cushy private school walls. Kevin (Steve Howey) and V (Shanola Hampton) juggle the demands of raising the twins with running the Alibi as they attempt to transform the bar into a socially conscious business. Shameless will premiere September 9 at 9 p.m. Immediately afterward at 10 p.m., Showtime will debut new half-hour comedy series Kidding starring Jim Carrey in his first series regular role in more than two decades, and reuniting him with director Michel Gondry (Eternal Sunshine of the Spotless Mind).

Executive Summary challenge for the USDA Forest Service is controlling the spread of invasive plants (weeds). Weeds Ahave a profound biological, economic, and social impact on U.S. forests and rangelands, and both their populations and control costs are growing exponentially. Some have been introduced into this country acci- dentally, but most were brought here as ornamentals or for livestock forage. These plants arrived without their natural predators of insects and diseases that tend to keep native plants in natural balance. They infest forest and rangelands, increasingly eroding land productivity, hindering land use, and management activi- ties. They are altering native plant communities, nutrient cycling, and hydrology; they are degrading ripari- an areas, altering fire regimes and the intensity of wildfires, as well as disrupting recreational experiences.
