  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • What’s in Your Water

    Water can be said to be the essence of life. Indeed, in many indigenous cultures, water is strongly linked to a people’s cultural identity. With the unfortunate news about the amount of lead found in Flint, Michigan’s public water system, perhaps more scrutiny and resources will be designated to improve and monitor this vital resource. But before you pour water into your glass, ...

  • Algal blooms: What are they?

    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 ...

  • 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 ...

  • GTI Covers Tackle Troublesome Algae at Clarksville Water Treatment Plant

    The Utility: The Clarksville Water System consists of a water treatment plant and a distribution system that serves approximately 160,000 people, making it one of the largest in Tennessee. The Clarksville Water Treatment Plant is situated on an 11 acre (4.5 hectare) site beside the Cumberland River, the city’s source of water, and has an estimated capacity of 28 MGD with peak rates ...

  • Occurrence of algae and algae-related taste and odour (T&O) compounds in the Qingcaosha Reservoir, China

    This study examined the temporal and spatial variations in the occurrence of major algae and algae-related taste and odour (T&O) compounds in Qingcaosha Reservoir, China. Water samples were collected monthly from seven sites in the reservoir and analysed using solid phase microextraction combined with gas chromatography-mass spectrometry. Results showed that green algae were dominant over ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Simple Quantitative Measurement of Nannochloropsis Micro Algae in Water Using Shimadzu UV Micro Algae Analysis System

    Global warming due to the burning of fossil fuels is now widely recognized as a problem, and among the alternatives to fossil fuels, the extraction of fuel from micro algae has been actively investigated in recent years. While the yield per unit area of micro algae is high, and harvesting is possible year round, these advantages are offset by many challenges in the development process that ...

  • Characterization of Algae 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 ...

  • Operation of an integrated algae pond system for the treatment of municipal sewage: a South African case study

    Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect sewage treatment. In the present work, the performance of IAPS was evaluated to determine the efficiency of this technology for treatment of municipal sewage under South African conditions. Composite samples were analysed over an 8 month period before and after tertiary treatment. ...

  • Principal component analysis to assess the efficiency and mechanism for ultraviolet-C/polyaluminum chloride enhanced coagulation of algae-laden water

    Polyaluminum chloride (PAC) coagulation, short wavelength ultraviolet (UV-C at 254 nm) treatment and UV-C/PAC treatment of algae-laden water from Meiliang Gulf (Lake Taihu) were conducted. The intrinsic characteristics and correlations of chromophoric dissolved organic matter (CDOM), algae biomass and other contaminants were investigated. Parallel factor analysis determined four CDOM components, ...

  • Sorption of heavy metals in the biomass of alga Palmaria palmata

    Sorption of heavy metals by the sea alga Palmaria palmata was investigated in laboratory conditions. The sorption process of the analytes was carried out with constant flow of the solutions through the algae samples. The Langmuir isotherm model was used to describe equilibria. The experiments confirmed that 50 min of exposure of algae with little heavy metal contamination in contaminated ...
