  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Ultrasonic selectivity on depressing photosynthesis of cyanobacteria and green algae probed by chlorophyll-a fluorescence transient

    Ultrasound can inhibit cyanobacterial growth through rupturing cells, but this pathway frequently has the risk to release intercellular toxin (e.g., microcystin). Depressing photosynthesis without cell disruption may provide a new strategy to control cyanobacterial blooms using ultrasound, especially Microcystis blooms. In this work, Microcystis aeruginosa (toxic ...

  • 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 ...

  • Control and monitor Algae in a Lake - Case Study

    As part of the Clearwater PMPC project, 2 MPC Buoys were deployed in the Skrzyneckie Małe Lake to test the performance of this unique technology. The Challenge: Control and Monitor Toxic Algal Blooms The ClearWaterPMPC project was initiated by LG Sound and funded by "Research for SMEs" within the EU 7th Framework Programme. The goal of the ClearWaterPMPC (Predicting, ...

  • 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 ...

  • Impacts of Climate Change on the Occurrence of Harmful Algal Blooms

    Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...

  • Maternal repeated oral exposure to microcystin‐LR affects neurobehaviors in developing rats

    Microcystins are toxic peptides secreted by certain waterblooms of toxic cyanobacteria. The most widely studied microcystin is microcystin‐LR (MC‐LR), which exhibits hepatotoxicity and neurotoxicity. However, limited information is available regarding the effects on offspring following maternal exposure. The present study is to observe the effects of progestational exposure to MC‐LR on ...

  • Long‐term effects of the antibacterial agent triclosan on marine periphyton communities

    Triclosan (TCS) is a widely used antibacterial agent that has become an ubiquitous contaminant in freshwater, estuary and marine environments. Concerns for potential adverse effects of TCS have been described in several recent risk assessments. Effects on freshwater microbial communities have been quite well studied but studies addressing effects on marine microbial communities are scarce. ...

  • Economic impact of algae blooms

    How much does an algae bloom cost? What is the price of inaction? Algae and cyanobacteria blooms are issues of considerable concern for environmental agencies, drinking water companies, municipalities and people alike. The incidence of Harmful Algae Blooms (HAB), along with its adverse effects, have been increasing in recent years as a result of climate change, increased fertilizer runoffs into ...

  • Solar-Powered Circulation Technology Clears Out Blue-Green Algae without the Costs and Hazards of Copper Sulfate

    Untitled Document As the annual onslaught of blue-green algae (cyanobacteria) blooms continues to plague fresh water lakes and reservoirs, the use of copper sulfate to control the problem has ...

  • The Potential of Solar-Powered Water Circulators to Help Solve Serious Water and Energy Problems in the U.S.

    With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers ...

  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...

  • Industrial Biotechnology: Coordinated Framework Make-Over and Lots More

    The summer of 2015 was surprisingly busy in the industrial biotechnology policy and regulatory arenas with three important announcements generating lots of buzz. On July 2, 2015, theWhite House Office of Science and Technology Policy (OSTP), the Office of Management and Budget (OMB), the US Trade Representative, and the Council on Environmental Quality issued a memorandum directing the US ...
