How pre-treatment is the solution for moldy smells and clogged filters

Green waters are red flags Blue-green algae (Cyanobacteria) and green algae that bloom in drinking water sources degrade water quality and are likely to end up in water treatment plants, clogging sand filters, and pipes. Additionally, they produce geosmins and MIB, i.e., toxins that give water an earthy and moldy taste and smell, resulting in customer ...

Argentina’s Algae Challenge

In Argentina, green-blue algae have made their appearance in various lakes and lagoons. Not only do they smell bad – they hamper the growth of aquatic plants, threaten marine life, and cause health issues in humans due to the release of cyanotoxins. Besides, excess blooms also affect local fishing and touristic ...

Monitoring Harmful Algal Blooms in Summer

Monitoring Harmful Algal Blooms Late summer is a great time to be on the water. Hot sun, clear skies and warm water draw recreationists of all stripes—boaters, kayakers, swimmers, fishing enthusiasts—to the water, looking for one last hurrah before the onset of fall. In a few, unfortunate cases, however, late summer weather can contribute to a condition that is not so delightful and ...

Complying with NPDES effluent guidelines

To comply with the stringent NPDES effluent guidelines, it is vital to understand the mechanisms and interactions that affect the balance in the aquatic ecosystems. The National Pollutant Discharge Elimination System (NPDES) requires power plants in the U.S. to control their levels of harmful pollutants released in surface waters according to the specific effluent limitations. In this article, ...

Real-Time Monitoring Solution for Harmful Algal Blooms - Case Study

Background Microscopic plants (algae) that live in the sea will sometimes grow out of control and produce harmful toxins that can contaminate water and shell fish, kill animals, and sicken humans. These negative consequences can have large monetary effects that ripple across many industries. In 2011, it was estimated that health consequences due to marine-borne pathogens in the USA have annual ...

Tackle harmful algal blooms with near-surface circulation

Lake Varner in Newton County, Ga., about 35 miles east of Atlanta, has been plagued with harmful cyanobacteria (blue-green algae) blooms since the reservoir was built in 1992. At an average depth of 10 to 12 ft, the shallow lake water warms quickly in the spring, creating ideal breeding conditions for the blue-green algae blooms, which can contribute to taste and odor problems and be potentially ...

Nutrient Pollution and Algal Blooms: Causes and Solutions

Harmful algal blooms (HABs) appear more often, abundant, extensive, and toxic than ever. Each year, they affect diverse new water areas around the world. Many of these blooms are triggered by increasing nutrient pollution. The dramatic surge in nutrient flow from industrial, urban, and agricultural activities accelerate the eutrophication of lakes, streams, and coastal waters. Harmful algal ...

The Blob Returns

In the autumn of 2013, Nicholas Bond, who was then the State Climatologist for the state of Washington, first detected a large (500 miles wide x 300 feet deep), circular body of sea water which had not cooled as expected and was 2 to 3 degrees warmer than the rest of the surrounding Pacific Ocean. By mid-2014, this unnaturally warm patch of ocean had grown to 100 miles long x 1000 miles wide x ...

Algal blooms in drinking water reservoirs

Drinking water reservoirs worldwide often suffer from frequent outbreaks of algal blooms. Their water quality degrades and becomes undrinkable. Algal blooms can grow so massive that they are even visible from outer space. Rising temperatures, extreme weather, stagnant water, and excess of nutrients accelerate algae growth. On hot summers, algae can grow very fast forming dense surface ...

HABs are an expensive issue

Microscopic algae (phytoplankton) is an important part of the ecosystem because in the presence of sunlight, they produce oxygen through photosynthesis and release this oxygen into the water. However, its massive growth and the production of toxins can generate negative impacts. These natural events known as Harmful Algal Blooms (HAB), can affect aquatic life, human health and local ...
