Surface Water / Algae Blooms Case Study
Challenge The city river in Berlin is contaminated to the point that fish death events are common. Combined sewage overflows, stormwater runoff and the high traffic of ships are the main sources of contamination. The high amount of nutrients and the high tempratures in the summer make the river prone to algae blooms. For these reasons, the shore of the river was selected as the first pilot ...

Study reveals toxic algae blooms poisoning bull sharks in the Indian River Lagoon
A new study shows that toxic algae blooms are poisoning bull sharks in the Indian River Lagoon and posing a risk to human health. The harmful algae blooms also have caused a widespread loss of seagrass and an unprecedented die-off of manatees in the area. Aside from environmental impacts, toxic algae bloom also has economic consequences. Toxic algae blooms are a growing concern in many ...

Toxic algae outbreak endangers Chile’s Lake Villarica
Toxic algae blooms have been a growing concern in Chile in recent years, as they threaten the health of people and animals that come into contact with them. The blooms have been caused by the proliferation of microorganisms known as cyanobacteria, which can produce harmful toxins. One of the most affected areas is Lake Villarrica in the La Araucanía region, where a toxic algae bloom has ...

Water drones hunt down, combat toxic algae
As air drones already exist, a new development has evolved in drone technology, a water-based drone to ensure fast and efficient algae control and treatment. Combating algae is known as a complicated process which requires accurate measurements. A European consortium would like to present the DRONIC project, which will change algae treatment into a new technology that can simplify and bring it ...

Extreme Algae Blooms that Plague the US
Beaches are covered with thousands of dead fish. More than 260 tons of marine life washed ashore, lying breathless across 150 miles. It’s not a war zone, it’s the horrifying consequence of an algae bloom in Tampa Bay, Florida. In recent years, freshwater lakes, ponds, and many other waterways in the United States have been dealing with an increasing number of harmful algae blooms ...

How climate change fuels algae blooms in the 21st century
Algae are a common occurrence in all marine and freshwater ecosystems, and they play an important role in both coastal fisheries production and ecosystem function. However, they can also lead to major environmental problems. Algae blooms occur when algae grow rapidly and form dense, visible patches on the surface of bodies of water. While some algae blooms are harmless, others can release toxins ...

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 ...

Algae control in wastewater treatment plant
Description One of the main challenges faced by Wastewater Treatment Plants (WWTPs) is the control of algae blooms. High algae concentrations create problems for process performance and increase operating expenditure for cleaning and maintenance activities. Results The LUS has shown to be a viable solution at controlling algae growth in the balance tanks at ATP. The results include: ...

World Economic Forum shares LG Sonic CEO’s vision on algal blooms
While we experience terrible drought and flooding events due to climate change, another significant hazard is hidden beneath the surface. The fragile state of the world’s freshwater. In his opinion article for the World Economic Forum, LG Sonic CEO Yousef Yousef shares his concerns on the nitrogen and phosphorous accumulations in lakes. This, in turn, is triggering Harmful Algal Blooms ...

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 ...

Notable increases in nutrient concentrations in a shallow lake during seasonal ice growth
Nutrients may be eliminated from ice when liquid water is freezing, resulting in enhanced concentrations in the unfrozen water. The nutrients diluted from the ice may contribute to accumulated concentrations in sediment during winter and an increased risk of algae blooms during the following spring and summer. The objective of this study was to evaluate the influence of ice cover on nitrogen ...

The role of aeration in water features
In warm weather, the surface of your lovely water feature sucdenly develops a green, slimy mass which looks as if it may begin to pulsate, eave the water, and threaten the surrounding countryside, like the monstrous entity in some early Steve McQueen B movie Your instinct may be to use extreme measures - the chemical equivalent of calling in the National Guard for a tactical nuclear strike. ...

Algae Bloom Detection for Desalination Plants
Despite the fact that water covers 70 percent of the planet, a mere 3 percent of that water is fresh. Most of the planet’s freshwater is not readily available. The water systems that perpetuate ecosystems are stressed by a growing human population, disappearing wetlands, agricultural consumption and droughts related to climate change. At present, 14 of the world’s 20 largest cities ...

Overview of WaterScope technology
Background A harmful algal bloom (HAB) contains algae that not only lowers oxygen levels in natural waters but can produce toxins as well. While algae are important species in water ecosystems by recycling nutrients and thus providing food for other organism, their rapid growth, referred as algae bloom, can be harmful not only for the ecosystem itself but also for branches of economy, relying on ...
