  • 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 ...

  • Harmful algal blooms: new methods of control and management

    The general increase in eutrophication of waters and the changes in global climatic conditions have caused over the last 30 years the spread of algal blooms in seas all over the world. The paper describes the different aspects of this problem, the known classes of marine algal toxins and their effects on human activities, and the problem of ballast waters. New strategies of remote sensing ...

  • 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 ...

  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Algal Treatments

    Global warming means algal blooms can only increase. Tom Hall of the WRc Group reports on the latest research into treatment programmes Excessive algal growth in raw water reservoirs can cause severe problems with water supply, even in a traditional UK climate. Global warming means algal problems could become more frequent and acute in the UK, so effective control measures will become more ...

  • 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 ...

  • Phycotoxins in the marine environment: control of marine organisms for contamination with algal toxins

    On a global scale, the frequency and intensity of toxic algal blooms appear to be on the rise. There is also evidence of geographic spreading of toxic strains. Therefore, it is necessary to establish methods for the evaluation of possible hazards caused by the enrichment of algal toxins in the marine food chain. Different clinical types of algae-related poisoning have attracted scientific ...

  • 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 ...

  • 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 ...

  • Long-term effects of hydrometeorological and water quality conditions on algal dynamics in the Paldang dam watershed, Korea

    The primary goal of this study is to shed light on some important factors that control algal bloom in a large-scale regulated river system. Long-term impacts of environmental conditions on algal dynamics were investigated in the Paldang dam watershed, Korea. Dam inflow, water temperature, chlorophyll-a, TN, PO4-P and TP data collected at five major dams located on the North Han ...

  • 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 ...

  • Case study - Control and monitor algae in a lake

    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, ...

  • Using UV for Simultaneous Disinfection and Control of Unpleasant Tastes and Odors in Drinking Water

    Algae blooms in surface water sources often lead to off-tastes and odors in finished drinking water. Because public confidence in overall drinking water quality is closely related to aesthetic quality, there is increasing interest in solving taste and odor issues.  UV-oxidation, the combination of UV and hydrogen peroxide, offers the ability to treat taste and odor (T&O) while simultaneously ...
