  • Global advances in nutrient pollution

    The UK’s Thames Water and Canada-based Ostara Nutrient Recovery Technologies are to form a partnership to build and operate Europe’s first wastewater treatment facility that removes phosphorus and converts it into commercial fertilizer. However, the USGS reports that phosphorus levels in US fresh water remain high and progress is absent. American environmentalist Robert F. Kennedy, ...

  • Human and physical geography affect organic nutrients in streams

    Rainfall causes carbon, nitrogen and phosphorus, dissolved from natural, agricultural and urban sources, to run into rivers. This can affect water quality by promoting eutrophication, pollution and affecting water temperature and clarity. Researchers have recently studied differences in concentrations of these nutrients in streams across Europe. The Water Framework1 and Urban Wastewater2 ...

  • NACWA affirms commitment to water quality monitoring for nutrients

    The National Association of Clean Water Agencies (NACWA) supports the collection of robust water quality data for nutrients to ensure scientifically based decision-making.

  • City of York and Ostara Nutrient Recovery Technologies Open Commercial Nutrient Recovery Facility

    YORK, PA - The City of York and Ostara Nutrient Recovery Technologies Inc. will officially open a new Nutrient Recovery Facility at the York Wastewater Treatment Plant (York WWTP) today at 11:30 a.m. This unveiling will mark the opening of the second facility in the nutrient-sensitive Chesapeake Bay watershed. Ostara's technology, called the Pearl® Nutrient Recovery Process, recovers ...

  • North Sea needs more protection from nutrient inputs

    Reductions in the nutrients nitrogen and phosphorus flowing from rivers into the North Sea have had clear benefits on marine health in coastal waters, according to a recent study. However, the reductions are less effective in improving the condition of deeper offshore waters. Tougher measures to manage nutrient loads and prevent eutrophication are recommended. Reductions in nutrient levels in ...

  • Sandia Algae Researchers Cut Costs with Improved Nutrient Recycling

    Algae are a promising source of renewable biofuels and bioproducts, and researchers at Sandia National Laboratories in Livermore, California, are taking a step toward realizing the promise of sustainable, cost-effective algal biofuels for the American public. Sandia molecular biologists Todd Lane and Ryan Davis, leading a team with OpenAlgae and Texas A&M AgriLife Research, ...

  • Madison Metropolitan Sewerage District and Ostara Partner to Install Commercial Nutrient Recovery Facility

    MADISON, WI and VANCOUVER, BC - The Madison Metropolitan Sewerage District (MMSD) and Ostara Nutrient Recovery Technologies Inc. have partnered to install a new Nutrient Recovery Facility at MMSD's Nine Springs Wastewater Treatment Plant. The District, which serves 340,000 people in the cities, towns and villages surrounding Madison, selected Ostara's Pearl® Nutrient Recovery technology for ...

  • Climate change increases eutrophication in the Baltic Sea

    Model projections of the Baltic Sea show that changes will occur in the marine environment in a future climate. Nutrient load reductions to the Baltic Sea are of even higher importance in a warmer climate. A modeling tool has been developed to support decision making. New climate-change scenarios for the Baltic Sea show that the water temperature will increase and the salinity will decrease. ...

  • Improving local conditions can improve ecosystem resilience to global changes

    Improving local water quality could mitigate the damaging effects of rising CO2 on marine ecosystems, new research suggests. Scientists in Australia found that nitrogen pollution in seawater, when acting in combination with heightened CO2 concentrations, had a significant effect on the growth of turfing algae, which displace kelp forest ecosystems. In today’s world, pressures on ...

  • Mission markets musings: Theda 6braddock

    Mission Markets Blog Stormwater runoff has been identified as one of the largest sources of pollutants in the Nation’s waterways. Stormwater is rain and snow melt that runs off impervious surfaces such as roads and rooftops. In the draining process, the runoff picks up chemicals such as nitrogen and phosphorus as well as oil, heavy ...

  • The effect of global warming on eutrophication in lakes

    Shallow lakes are an important type of ecosystem that may be vulnerable to current warming trends. A recent study examines just how vulnerable they are. It indicates that climate change combined with nutrient pollution could exacerbate eutrophication and suggests nitrogen levels should be monitored. Shallow lakes are important in their support of biodiversity. However, their large ...

  • ASA Analytics introducing the ChemScan mini DeChlor at WEFTEC 2014, Booth #2760 South Hall

    ASA Analytics is introducing another set of paired ChemScan mini analyzers for process monitoring and control applications.  Last year ASA introduced the ChemScan mini FreeChlor, for analysis of free or total chlorine in water or wastewater at concentrations from 0.01 mg/l to 4.0 mg/l.  This year ...

  • How much phosphorus pollution makes lakes unsafe for recreation?

    A target level of 20 micrograms of phosphorus per litre of lake water could help keep many lakes safe for recreation by restricting the growth of harmful algal blooms, European research suggests. The scientists analysed the relationship between phosphorus levels in medium- and high-alkalinity lakes, the growth of cyanobacteria blooms and the concentrations of cyanobacteria that trigger World ...

  • New tool improves integrated river basin management

    A new computer system has been shown to provide a 'full picture' of a river basin's health, by taking into account all relevant influences, including rainfall, pollution and soil. The system integrates several existing environmental data programmes in a user-friendly way, and is aimed at helping the sustainable management of entire river catchment areas. The system, called the 'Elbe-DSS' (Elbe ...

  • EU call for regulation of wood ash fertilisers

    Wood ash may not be an ideal fertiliser for the forest after all, according to new research, which found high natural levels of toxic trace elements in wood ash. In addition, the study showed that adding wood ash could affect the forest soils in such a way that toxic elements are more rapidly released into the receiving waters. Wood ash is a by-product of wood burning which is classed as a form ...

  • Summertime...and the problem is algae

    Algae can spurt into growth when nutrient-rich UK tap water is used to top up ponds. So in the hot dry summer months the best course of action is to wait for the rain and, if possible, prepare for dry spells by collecting as much rainwater as possible. In hot, dry weather water evaporates from the surface of ponds and other wetlands. As the water level goes down, nutrients and pollutants are ...
