  • Monitoring of Algae Growth by TOC Measurement

    Global warming due to the excessive use of fossil fuels is becoming a problem which has prompted and accelerated the search for alternative fuels. Among the more attractive alternatives is biomass fuel, which is attracting considerable attention. Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other biofuels, its ...

  • Algae Enumeration and Identification

    Algae Enumeration and Identification Algae are ubiquitous in virtually all aquatic environments and are important bioindicators of water quality. They are frequently used to assess and monitor the health of aquatic systems. On the other hand, they are also responsible for imparting undesirable flavors to potable water supplies and pose potential health threats, particularly during algal blooms. ...

  • Algae Control Solution for Chilean Salmon Industry?

    Since February 2016, Salmon farms in Chile have been suffering from an intensive Harmful Algal Bloom (HAB) which is causing massive numbers of salmon deaths. Ultrasonic technology combined with algae detection could be the solution for an industry facing economic losses totaling millions. Currently the Dutch algae control company, LG Sonic, is discussing the implementation of ultrasonic ...

  • Linking the chemical speciation of Ce to its bioavailability in water for a freshwater alga

    Over the past decade, researchers have begun to use metals of the lanthanide family for numerous applications, including liquid crystal display (LCD) screens, optical fibers and laser technology. Unfortunately, little is presently known about their bioavailability or the mechanisms by which they might cause toxicity. This paper focuses on cerium, which is one of the most widely used ...

  • Levels of cadmium, manganese and lead in water and algae; Spirogyra aequinoctialis

    This study assessed the ability of filamentous green algae; Spirogyra aequinoctialis to accumulate manganese, cadmium and lead from water. Water pH was also determined. Samples of S. aequinoctialis and their respective water environments were taken from designated sampling points in the city of Blantyre and Malawi during the ...

  • Case study - Algae control in New Jersey raw water reservoir

    Four solar-powered algae control buoys were installed in the Canoe Brook Reservoir #1 in Short Hills, NJ to assess the impact of the system for controlling algae and cyanobacteria in the raw water reservoir. The four buoys operated for five months in the spring/summer 2014. The Challenge: Address Episodic Taste and Odor Events The primary objective of this project was to ...

  • Case study - Algae control in East Dorset raw water reservoir

    Bournemouth Water has installed four MPC-Buoy systems to monitor and control algal blooms at Longham Lakes. After the installation of the MPC-Buoy systems a dramatic reduction in the concentration of algae was experienced. The Challenge: Installing an Environmentally Friendly Solution to Control Algal Blooms The objective of the project was to reduce algae concentrations . ...

  • 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 ...

  • Cadmium accumulation and toxicity in the unicellular alga Pseudokirchneriella subcapitata: Influence of metal‐binding exudates and exposure time

    Predicting metal availability and toxicity for chronic (several hours or days) metal exposure scenarios, even for unicellular algae, is a major challenge to existing toxicity models. This is because several factors affecting metal uptake/toxicity, such as the release of metalbinding exudates, changes in the kinetics of metal uptake/toxicity over time and algal physiological acclimation to ...

  • Influence of essential elements on cadmium uptake and toxicity in a unicellular green alga: The protective effect of trace zinc and cobalt concentrations

    Within the biotic ligand model (BLM) construct, major cations are considered to be simple competitors for metal binding to uptake sites and may offer some protection against metal‐induced toxicity, but the influence of essential trace elements and cell preconditioning to different micronutrient concentrations on metal uptake and toxicity is considered negligible. To test these underlying ...

  • Biomonitoring can measure what chemical monitoring cannot

    Algae and Daphnia (waterfleas) forewarn drinking water sector Biomonitors, instruments which measure the biological effects of different substances on organisms, detect substances which cannot be detected using chemicals anaylsis methods. This is also valid for combinations of substances which are present in the water in large concentrations. A well-functioning monitor is necessary since our ...
