  • 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. ...

  • Nitrogen removal in maturation waste stabilisation ponds via biological uptake and sedimentation of dead biomass

    In this work a set of experiments was undertaken in a pilot-scale WSP system to determine the importance of organic nitrogen sedimentation on ammonium and total nitrogen removals in maturation ponds and its seasonal variation under British weather conditions, from September 2004 to May 2007. The nitrogen content in collected sediment samples varied from 4.17% to 6.78% (dry weight) and calculated ...

  • 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 ...

  • The impact of Toxic Substances Control Act nomenclature on the commercialization of biobased chemicals

    Regulatory Review is a regular column featuring updates on regulatory matters concerning oils- and fats-related industries. Moving from bench to market Many small companies or those new to chemical manufacturing are not aware of their obligations under TSCA. Most biobased chemical companies have likely operated under the research and development (R&D) ...

  • Cooling tower case study

    Cooling towers have always been difficult to control. Algae grow in the cooling tower itself and on the grids used. In addition to micro-organisms and biofilm, they reduce the efficiency of the cooling tower. Furthermore the risk of spreading Legionella is a serous factor to be reckoned with. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally ...

  • Ultrasonic technology in cooling towers

    Ultrasound technology is an effective and environmentally friendly method to minimise chemical consumption and improve the efficiency of a cooling tower, says Ander Paz Blazquez. Low-intensity ultrasound has been used for more than a decade in order to control algae and biofilm growth. Latest innovations have concluded that effective algae control is achieved through the use Ultrasound ...

  • Removing biofilm from membranes – a practical approach

    Abstract Within the lifetime of most reverse osmosis (RO) systems some fouling will adversely affect membrane performance.One of the major foulants identified on lead membranes during a decade of membrane autopsy at the Genesys Membrane laboratory is biological fouling (biofouling). All raw water sources contain microorganisms such as algae, bacteria and fungi. They also contain ...

  • Water treatment case study

    Wastewater is any water that has suffered in quality by human intervention. Often, wastewater is being treated for re-use as drinking water or for other purposes. As high levels of nutrition are available in these waters, algae may grow rapidly as well as other micro-organisms such as bacteria. Algae can compete for nutrients against the bacteria in charge of sludge reduction and can also clog ...

  • Whole Effluent Toxicity Testing

    What is Whole Effluent Toxicity (WET) testing? Whole Effluent Toxicity (WET) testing is an important component of the U.S. Environmental Protection Agency’s (USEPA’s) integrated approach for detecting and addressing toxicity in surface waters. The National Pollutant Discharge  Elimination System (NPDES) permit program, authorized by the Clean Water Act, controls water pollution by ...

  • Mixed Oxidant Replaces “Cocktail” of Chemicals in Power Plan

    Cooling Tower Water Systes Synopsis In 2010 NIPSCO installed two MIOX RIO Mixed Oxidant Solution (MOS) chlorine generator systems on two of the four cooling towers at R.M. Schahfer Generating Station.  After switching to MIOX for cooling tower water treatment, the two towers experienced minimized algae growth, better biocontrol and lower Legionella counts, ...

  • An essential guide to water treatment solutions & its steps

    The scarcity of water is one of the biggest issues faced by the current generation. Due to the changes in climatic pattern, rising number of industrial employments and other commercial residues, the remaining water sources have kept on being polluted, and hence, the level of drinkable and safe water is dropping at an alarming rate. Currently, while the level of wastewater is rising, on the other ...

  • Drinking Water Treatment Process

    Most drinking water comes from a surface water source, such as a lake or river, or a groundwater source, such as a well or spring. This water requires treatment before it can be safely consumed; the level to which the water is treated depends on the source of the water and also on federal regulations. In the United States, for example, the Safe Drinking Water Act was created by the Environmental ...
