  • Solar-driven photocatalytic decomposition of microcystin-LR: from laboratory development to on-site demonstration

    Harmful algal blooms (HABs) found in various water bodies worldwide have been a huge concern due to their adverse impacts on human health and ecosystems. In particular, HABs associated with cyanobacteria have been of great interest because of their potential to generate and release biological toxins, especially, lethal microcystins (MCs). The overall goal of this study was to develop a new ...

  • Influence of environmental variables on saxitoxin yields by Cylindrospermopsis raciborskii in a mesotrophic subtropical reservoir

    Saxitoxins are a class of toxins produced by at least two groups of evolutionarily distant organisms (cyanobacteria and dinoflagellates). While the toxicity of these toxins is relatively well characterized, to date little is known about their drivers and ecological functions, especially in lower latitude tropical and subtropical freshwater ecosystems. In the present study, we aimed to obtain a ...

  • 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 ...

  • Progress in Lake Restoration Science

    The media almost always gets the story wrong about effective methods to eliminate cyanobacteria blooms in lakes (otherwise known as blue-green algae or harmful algal blooms (HABs). The actual track records for the most talked-about methods are astoundingly poor, about “0 wins” vs “5000 losses” since the U.S. Clean Water Act was passed in 1970. Usually the articles talk ...

  • Algae Control in Lakes and Reservoirs

    There are plenty of harmful algal bloom related cases worldwide but what is evident is that their number elevates with each year. Excessive cyanobacteria (blue-green algae) and green algae growth in a water reservoir can have negative consequences for the water quality. The water turns green, sand filters can clog, and some algae can produce geosmins and MIB, giving the water an ...

  • Are Lake Alum Application Strategies Set Up For Failure?

    Since 2012, we have been working with stakeholders at a high value 300-acre lake in the US. They have been considering putting in SolarBee® Lake Circulators to control toxic blue-green algae (cyanobacteria) blooms. So far however, they have opted to apply aluminum sulfate (alum) in an effort to tie up phosphorus at the sediment (thus preventing "internal loading” or recycling of ...

  • Review: The Role of Phosphorus & Nitrogen in Freshwater Algae Blooms

    In August 2016, Environmental Science & Technology published an article about preventing or reducing harmful algae blooms in freshwater lakes. "Reducing Phosphorus to Curb Lake Eutrophication is a Success” was co-written by several lake scientists from the United States & Canada with D. Schindler (Edmonton, Alberta) as the lead author.

  • Nutrient enrichment and vertical mixing mediate 2-methylisoborneol and geosmin concentrations in a drinking water reservoir

    Few ecosystem-level studies have experimentally determined the physicochemical and biological factors that mediate concentrations of off-flavor compounds in drinking water reservoirs. Consequently, the watershed-scale mechanisms determining production of these compounds are still poorly understood. In a recent study, the addition of both nitrogen and phosphorus significantly increased ...

  • Algal bloom causes and prevention

    Algal blooms are also known as marine blooms or water blooms, and are actually a sudden increase in the population of algae in water scenery. Algal blooms usually take place in freshwater, such as lakes and water reservoirs as well as in marine milieus. They can be easily identified by coloration of the water ensuing from the high density of pigmented cells. Though many types of algae can form ...

  • Identification and assessment of water quality risks associated with sludge supernatant recycling in the presence of cyanobacteria

    This study focussed on the fate of cyanobacteria cells and associated metabolites during the sludge management processes that follow the conventional drinking water treatment train. The topic is of importance, as the release of metabolites during sludge treatment may pose a risk to water quality if supernatant is recycled to the head of the plant. The study of the kinetics of cell damage and ...

  • Relations between abundance of potential geosmin- and 2-MIB-producing organisms and concentrations of these compounds in water from three Australian reservoirs

    Relationships between the abundance of potential geosmin- and 2-methylisoborneol-producing (2-MIB) cyanobacteria and bacteria, and concentrations of the two taste and odour compounds (T&Os) were examined in a 7 day incubation of natural water from the surface and bottom of three reservoirs in southeast Queensland, Australia. Only a single known T&O-producing cyanobacterium ...

  • The “nutrient pump:” Iron-poor sediments fuel low nitrogen-to- phosphorus ratios and cyanobacterial blooms in polymictic lakes

    Abstract Several lines of evidence from a eutrophic lake show how polymixis enables phosphorus (P) released from anoxic, iron (Fe)-poor sediments to lower nitrogen-to-phosphorus (N : P) ratios and stimulate cyanobacterial blooms. Detailed sediment analyses revealed extensive formation of Fe sulfides, which suppressed porewater Fe levels and prevented sequestration of P in Fe minerals. ...

  • Iron based sustainable greener technologies to treat cyanobacteria and microcystin-LR in water

    The presence of the toxic cyanobacteria and cyanotoxin, microcystin-LR (MC-LR) and other cyanotoxins, in drinking water sources poses a serious risk to public health. Iron based technologies using magnetic zero-valent iron nanoparticles (nZVI) and ferrate ion (FeVIO42−, Fe(VI)) represent greener approaches to remove cyanobacteria and degrade MC-LR in water. This paper reveals ...
