  • 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 ...

  • Algal blooms in drinking water reservoirs

    Frequent outbreaks of algal blooms are degrading water in drinking water reservoirs worldwide, making the water unusable. Algal blooms can sometimes be so massive that they are visible from outer space. Rising temperatures, prolonged water stagnation, extreme weather and increased runoff of nutrients from urban and agricultural lands are all compounding the algae problem. Especially in the ...

  • How Ultrasound Controls Algae

    Controlling algae with low-power ultrasound is a well-established technology that has been in existence for many years. It is an environmentally-friendly technology that is harmless to fish and plants. This article explains how ultrasound controls algae, including the five most common questions related to ultrasonic algae control. Algal blooms cause reduced light penetration, depletion of oxygen, ...

  • 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 ...

  • Ultrasonic depth sensor to measure water levels

    The Dutch algae control company LG Sonic introduced an ultrasonic depth sensor to give the customers real-time insight in the water levels which allows them to adequately deal with water level fluctuations. Reservoirs used for industrial processes or the production of drinking water often deal with strong water level fluctuations. Due to events of high demand and evaporation, water levels in ...

  • 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 ...

  • Potential bioavailability of phosphorus in citrus orchard soil to Microcystis aeruginosa

    Algal blooms in eutrophic water bodies are controlled by inputs of phosphorus (P) as the growth-limiting nutrient. Runoff particulate P associated with soil from fields often predominates among P fractions. Here, an algal bioassay to investigate the potential bioavailability of particulate P in soil collected from a citrus orchard was conducted. Microcystis aeruginosa was cultured in medium ...

  • 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 ...

  • 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 ...
