  • Algae control in Auckland Dam - Case Study

    Five solar-powered algae control systems where installed in the Lower Nihotupu Dam in Auckland, New Zealand to reduce the levels of blue-green algae. The project started in December 2016 and so far, the project appeared to be of great success with the blue-green algae count over summer 90 per cent less than the previous year. The Challenge: Reduce Blue-green Algae Count The ...

  • Blue green algae in Harbour case study

    In May 2007 LG Sound proposed treatment for a harbour in the Netherlands, called Tholen. The harbour, which measured approximately 1 Km in length, suffered badly from blue-green algae growth. Blue-green algae produce toxins, which can be harmful form humans and animals and lead to major fish die offs. The toxin concentration and smell in the harbour from Tholen was so bad that recreational use ...

  • Two cyanobacterial strains can be distinguished from each other and other eukaryotic algae by spectral absorption method

    Spectral absorption method based on two step linear regression analyses (TSLR) was applied for detection of two strains of cyanobacterium, Microcystis (blue-green algae) from eukaryotic algae. Both blue-green algae, algae and dissolved organic carbon (DOC) were considered from freshwater bodies in Kanto region, Japan. The results show that blue-green species can be detected from other algal ...

  • Algae control in Tamam Aman lake - Case Study

    Lake Taman Aman is contaminated by algae and the inflow of liquid waste from the surrounding buildings. Thanks to the blooming of blue-green algae, the lake suffered particularly from malodour. In September 2012, 4 LG Sonic’s where installed in the lake to deal with the stench. The Challenge: Malodor Because of Blue-Green Algae Lake Tamam Aman is contaminated by algae ...

  • Nitrate reductase activity: A solution to nitrate problems tested in free and Immobilized algal cells in presence of heavy metals

    Every organism has different potential to accumulate NO3- from the environment. Nitrate reduction processes are perhaps most significant in maintaining water quality by alteration of nitrate to nitrite. A comparative study between the nitrate reductase NR activity of green and blue green algae in presence of heavy metals is being conducted to present a situation where nitrate reductase process ...

  • Blue-Green algae control and WTP cost savings (ID206) - Case study

    Topics: Raw water, blue green algae, taste and odor, treatment savings, improve fishery, water clarity Customer: Information is available upon request from Medora Corporation. 866-437-8076 info@medoraco.com Overview: This lake is an 850+ acre man-made reservoir feeding the a Water Treatment Plant (WTP) for a county. The WTP production capacity was ten (10) to ...

  • Tackle harmful algal blooms with near-surface circulation

    Lake Varner in Newton County, Ga., about 35 miles east of Atlanta, has been plagued with harmful cyanobacteria (blue-green algae) blooms since the reservoir was built in 1992. At an average depth of 10 to 12 ft, the shallow lake water warms quickly in the spring, creating ideal breeding conditions for the blue-green algae blooms, which can contribute to taste and odor problems and be potentially ...

  • Tackle Harmful Algal Blooms With Near-Surface Circulation - Case study

    A Georgia county is winning the battle with blue-green algae (cyanobacteria) on its surface water supply through near-surface circulation. Circulators paid for themselves in three years, cut the need for chemicals, restored water quality and the natural food chain, and eliminated taste-and-odor issues for potable water customers. LAKE VARNER in Newton County, Ga., about 35 miles east of ...

  • Improved oxygen conditions in the Baltic deep water

    Oxygen conditions in the south eastern Baltic have improved thanks to an inflow of oxygen-rich water from the North Sea during November/December 2011. This inflow has also caused the concentrations of phosphate and silicate to increase in the surface waters, which could cause excessive algal blooms this summer. As a result of the relatively large inflow from the Kattegat to the Baltic ...

  • What’s in Your Water

    Water can be said to be the essence of life. Indeed, in many indigenous cultures, water is strongly linked to a people’s cultural identity. With the unfortunate news about the amount of lead found in Flint, Michigan’s public water system, perhaps more scrutiny and resources will be designated to improve and monitor this vital resource. But before you pour water into your glass, ...

  • Wilmington OH - Eliminating Copper Sulphate - Case Study

    The dominant blue-green algae were Cylindrospermopsin and Microcystis, requiring frequent use of Copper Sulfate treatments to reduce the algae prior to the treatment plant. Ultrasound just as effective in controlling the algae Reservoir is clearer than it has been historically Overall lower cyanobacteria count ...

  • Genotoxicity of disinfection by-products (DBPs) upon chlorination of nine different freshwater algal species at variable reaction time

    Nine local dominant freshwater algal species, including green algae (Chlorella sp., Chlamydomonas sp. and Scenedesmus quadricauda), diatom (Navicula pelliculosa, Nitzschia palea Grunow and Synedra sp.), blue-green algae (Microcystis sp., Chroococcus sp. and ...

  • Cyanobacterial Blooms

    Cyanobacterial blooms can lead to a depletion of oxygen in the water, a release of toxins, as well as taste and odour problems. Cyanobacteria, also known as blue-green algae are found in the oldest known fossils, dating back 3.5 billion years. They were the organisms that caused the first mass extinction on earth, but are also the reason for the earth as we know it today. They released the first ...
