How dangerous is blue green algae?
Blue green algae is one of the popular parameters that can be tested using our water monitoring equipment. It is a common water pollutant that can have a severe impact on ecosystems and plant and animal life. Read more in our exclusive LinkedIn article, where our MD Craig Harrison explains in detail just how dangerous blue green algae is, and why it is so important to track. ...

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 main objective for ...

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 ...

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 ...

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 and the inflow of ...

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 ...

SRS Crisafulli dredge removes sediment and improves water quality Power Lake, North Dakota, USA - Case Study
Outbreaks of blue-green algae in a 1,616-acre natural lake, created an emergent call to action in the 1990’s from the community of Powers Lake, North Dakota, USA. Due to blue-green algae blooms, the recreational value of Powers Lake plummeted and few people gathered or recreated there. Powers Lake Watershed Committee (PLWC) In 1998, the local community recognized the importance of Powers ...

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 ...

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 ...

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 (about 150 ...

Mixing in Two Effluent Storage Basins - Case Study
Long-term cyanobacteria (blue-green algae) and odor control achieved. Topics: cyanobacteria, blue-green algae, odor control, effluent storage basins, irrigation Basin Overview: Two effluent storage basins of similar size and depth. P1 Area: 3.6 acres P2 Area: 3 acres Max Depth: 8 feet Each basin receives 1.2 MGD of effluent from the WWTP which then recharge water reclamation facilties ...

Algae Problems
Almost everywhere where water is being stored, algae problems may occur. When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look ...

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 Gloeocapsa sp.) were isolated from source water reservoirs and cultivated in the laboratory. The algal biomass was chlorinated (20 ...

When Should I Use a Red Excitation Configuration?
When measuring chlorophyll levels using the C-FLUOR, a red excitation configuration is recommended for use in aquatic habitats that have high dissolved organics. Unlike blue excitation, red excitation does not have as much interference from dissolved organic matter (DOM) because DOM particles absorb blue excitation energy, not red. Also, a red excitation configuration is more sensitive to ...
