  • Why Interactive Ultrasonic Programs are Important to Effectively Control Algae

    Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively  ...

  • Why it is Important to Control Algae Growth

    A combination of high temperatures, stagnant water and nutrient overload can result in excessive algae growth. These so-called algal blooms can lead to a depletion of oxygen in the water, release of toxins and taste and odor problems. Without treatment, the algae will grow more every year, resulting in an unbalanced ecosystem. Therefore, it is important to control algal blooms for a healthy ...

  • Microbes Run the World

    Microbes run the world. They are the governing agents behind the conversion of key elements into vital biological forms. They remove toxins from their environments, and protect us from disease-causing organisms. Microbes do not, however, go to battle alone. Microbe armies live in complex communities that follow intricate processes and interactions to ensure environmental stability. Until ...

  • 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 ...

  • 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 ...

  • Algae control in an open balance tank - Case Study

    High algae concentrations create problems for process performance and increase operating expenditure for cleaning and maintenance activities. Several LG Sonic e-line devices were installed in a Wastewater Treatment Plant (WWTPs) in Melbourne, Australia in order to control algal blooms. The Challenge: Control Algal Blooms and Lower Maintenance Costs One of the main challenges ...

  • Isolation, identification, and algicidal activity of aerobic denitrifying bacterium R11 and its effect on Microcystis aeruginosa

    Recently, algicidal bacteria have attracted attention as possible agents for the inhibition of algal water blooms. In this study, an aerobic denitrifying bacterium, R11, with high algicidal activity against the toxic Microcystis aeruginosa was isolated from lake sediments. Based on its physiological characteristics and 16S rRNA gene sequence, it was identified as Raoultella, ...

  • 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 ...

  • 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 ...

  • Can harmful algal blooms be predicted?

    Summer 2015, as the eighth month of the year approaches (August), we are starting to hear and read in the news about sudden algal blooms occurring in freshwater lakes and marine environments. Many popular beach resorts have put up warning signs proclaiming the water is unsafe for recreational purposes. This is an understandable precautionary measure since phytoplankton abundance or more ...

  • Using PAC-modified clays to control black-bloom-induced black suspended matter in Lake Taihu: deposition and resuspension of black matter/clay flocs

    Flocculation using modified clays is a technique widely applied in the management of harmful algal blooms (HABs). Polyaluminum chloride (PAC) modified clay is an efficient flocculating agent in HAB control; however its effectiveness in black bloom management is still largely unknown. In the present study, PAC-modified clay was used to flocculate a black bloom under simulated flows. The ...

  • Lowering the blooms

    Algae blooms are a regular occurrence at the Canoe Brook Water Treatment Plant in Short Hills, New Jersey. Over the past five years, the plant team has tried various methods to control the growth, which typically persists for weeks or months during late spring and summer. Contributing to the problem is a fairly shallow reservoir that allows sunlight to penetrate to the bottom of the lake, and ...

  • Algal control and enhanced removal in drinking waters in Cairo, Egypt

    Algal blooms at the major water treatment plants in Egypt have been reported since 2006. While previous studies focused on algal types and their correlation with disinfection by-products, correlation between raw water quality and algal blooms were not explored. Therefore, a survey of Nile water quality parameters at a major water intake in the Greater Cairo Urban Region was conducted from ...

  • LG Sound integrates new technology to detect toxic algae blooms

    LG Sound introduces satellite remote sensing technology in order to detect toxic algae blooms. Satellite remote sensing allows for detection of water quality from a distance with information obtained from satellites. Together with several European universities we discovered that different types of algae require different types of ultrasonic treatment. Therefore, it is important to detect ...

  • Combined effects of the cyanobacterial toxin microcystin‐LR and environmental factors on life‐history traits of indigenous cladoceran Moina macrocopa

    Environmental factors are important in that they might interact with toxicants and could affect the concentration‐response relationship of the toxicants in the water environment. Microcystins (MCs) produced by algal blooming are natural toxins that exert severe impact on aquatic organisms. Despite the possibility of interaction effects between environmental factors and MCs, very few studies ...
