Algal Bloom Control Articles

World best filter material for purification of drinking When algal blooms put the sand filters under pressure, Thames Water started its own in-house research into new filter materials. Not only did the effort cure the constraint, the use of new filter materials has saved millions in investments. Fast Cleaning To purify water with sand takes a long ...

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 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 ...

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, ...

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 ...

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 . ...

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, ...

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, ...

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 ...

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 ...

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 ...

The North Atlantic Landscape Conservation Cooperative LCC (NA LCC) is a public‐private partnership that provides information to support conservation decisions that may be affected by global climate change (GCC) and other threats. The NA LCC region extends from southeast Virginia to the Canadian Maritime Provinces. Within this region, the U.S. National Climate Assessment documented increases in ...

There is mounting evidence that climate-changeinduced extreme events are expected to adversely affect the aquatic ecosystems and ecosystem services that they provide. To address this need to understand how climate, aquatic ecological, and social systems interact and how to manage these coupled systems, LimnoTech is participating with a large team of researchers (from Stanford University, the ...

Microalgae have been regarded as a pollutant causing algal blooms in lakes or reservoirs but have recently been considered as a useful source of biomass to produce biofuel or feed for livestock. For the algae particle separation process, carbon dioxide (CO2), one of the main greenhouse gases, is dissolved into a body of water rather than being emitted into atmosphere. This study aims at ...

Urban water in Gulf Cooperation Council countries is principally supplied from desalination plants. However, desalination could be interrupted by natural hazards such as cyclones or harmful algal blooms. Four scenarios have been considered to help public institutions in Muscat to establish a water strategy for emergency situations. The numerical simulations of groundwater pumping have shown that ...

Lake Champlain is significantly impaired by excess phosphorus loading, requiring frequent lake-wide monitoring for eutrophic conditions and algal blooms. Satellite remote sensing provides regular, synoptic coverage of algal production over large areas with better spatial and temporal resolution compared with in situ monitoring. This study developed two algal production models using Landsat ...

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. ...

In June 2012, the Brazilian public water company Sabesp decided to install one LG Sonic e-line device at their facultative oxidation lagoon in Itapetininga. The Challenge: Blue-green Algae Cause Operational Problems Nuisant odours caused by periodic occurrence of excessive quantities of filamentous, and blue-green algae were posing operational problems at the facultative ...
