  • Sorption of heavy metals in the biomass of alga Palmaria palmata

    Sorption of heavy metals by the sea alga Palmaria palmata was investigated in laboratory conditions. The sorption process of the analytes was carried out with constant flow of the solutions through the algae samples. The Langmuir isotherm model was used to describe equilibria. The experiments confirmed that 50 min of exposure of algae with little heavy metal contamination in contaminated ...

  • Algae Enumeration and Identification

    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. ...

  • All clear in lake Twiste

    Danger over for swimmers: what appears to be disgusting, is purely natural – algae Lake Twiste is clean and free of blue-green algae even if at the moment there is a large amount of filamentous algae present. However, this is not a problem and completely natural, Andreas Gründel, Environmental Engineer from the Hessen State Authority for the Environment and Geology explained. A ...

  • Test organisms behaviour on municipal and industrial wastewater quality assessment

    Industrial wastewaters quality became a target for the environmental toxicity assessment nowadays. When there are issues with complex effluents for which many chemicals cannot be quantified and/or interactive effects are likely to be significant, the use of bioassays with different test species becomes a more reliable way in the assessment of toxicity. Ecotoxicity evaluation of the several ...

  • Safety corner - Ergonomic considerations for the wastewater treatment plant

    If you have ever had your golf swing assessed or changed the height on your desk chair, you have had an ergonomic experience. Ergonomics is an assessment of work spaces to reduce physical injury produced by repetitive job requirements. Ergonomics considerations cross every work type, from golf pros to lab technicians. Review of body mechanics while performing a job, with options of change to ...

  • Control and monitor Algae in a Lake - Case Study

    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, ...

  • Heavy metals, PAHs and toxicity in stormwater wet detention ponds

    Concentrations of 6 different heavy metals and total polycyclic aromatic hydrocarbons (PAHs) were determined in stormwater runoff and in the pond water of two Danish wet detention ponds. The pond water samples were analyzed for toxic effects, using the algae Selenastrum capricornutum as a test organism. Stormwater and pond water from a catchment with light industry showed high levels of heavy ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • Can harmful algal blooms be predicted?

    Summer 2015, as the eighth month of the year approaches (August), we are starting to hear and read in the news about sudden algal blooms occurring in freshwater lakes and marine environments. Many popular beach resorts have put up warning signs proclaiming the water is unsafe for recreational purposes. This is an understandable precautionary measure since phytoplankton abundance or more ...

  • 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 ...
