  • 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 ...

  • How long does it take to get an algae monitoring system running?

    When I buy a new piece of technical equipment for my home, I want to be able to open it up and get it running, at least the basics, in about 5 or 10 minutes. Any more than that, and I think that I’ve bought an old version of a product. Nowadays technology isn’t just better, it should also be easier to use. When you buy industrial or research equipment, the setup process is usually ...

  • 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. ...

  • 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 ...

  • 6712 Sampler Monitoring of Blue-Green Algae in Lake Winnebago - Fond Du Lac, Wisconsin - Case Study

    The Teledyne Isco 6712 portable sampler was used to monitor not only the production of the blue-green algal in Lake Winnebago, but also any algae toxins that could contaminate the surrounding community’s drinking water. ...

  • 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 ...

  • Notable increases in nutrient concentrations in a shallow lake during seasonal ice growth

    Nutrients may be eliminated from ice when liquid water is freezing, resulting in enhanced concentrations in the unfrozen water. The nutrients diluted from the ice may contribute to accumulated concentrations in sediment during winter and an increased risk of algae blooms during the following spring and summer. The objective of this study was to evaluate the influence of ice cover on nitrogen ...

  • Surface Water / Algae Blooms Case Study

    Challenge The city river in Berlin is contaminated to the point that fish death events are common. Combined sewage overflows, stormwater runoff and the high traffic of ships are the main sources of contamination. The high amount of nutrients and the high tempratures in the summer make the river prone to algae blooms. For these reasons, the shore of the river was selected as the first ...

  • Case study - Algae control in raw water reservoir Ecuador

    Before the installation of the LG Sonic e-line equipment algae grew on the surface and settle down on the liner before entering the drinking water treatment plant. To cover the 24.000 m2 of water surface, it was decided to install 3 devices.   The Challenge: Green Algae Covering the Sides of the Lagoon Located in Santa Elena’s peninsula, the 42.000 m3 raw water ...

  • Case study - Algae control in an open balance tank

    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 ...

  • 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 . ...

  • Algae Problems

    Almost everywhere where water is being stored, algae problems may occur. When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look ...

  • Occurrence of phosphorus, iron, aluminum, silica, and calcium in a eutrophic lake during algae bloom sedimentation

    Phosphorus (P) in a water body is mainly controlled by the interaction between surface sediment and the overlying water column after the complete control of external pollution. Significant enhancement of P in a water body would cause eutrophication of lakes. Thus, a better understanding is needed of the occurrences of P between the sediment and water column in eutrophic lakes. Here, we ...
