    Water Testing for Environmental Applications

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many cases, there are restrictions on wastewater that is discharged to city sewer systems or to other publicly owned treatment facilities. Many jurisdictions even restrict or regulate the runoff of stormwater — affecting not only industrial and commercial land, but also residential properties as well.

    Waste recovery for petrochemical wastes

    Traditionally, the Petrochemical Sector has operated with basic technological solutions, with ultimate reliance on High Temperature Incineration (HTI) and landfill in order to deal with their hazardous wastes. However, tightening regulation, increasing landfill costs and social responsibilities are driving companies to look at alternative methods of treatment of very challenging wastes, including the treatment of:

    Wastewater treatment solutions for mining and primary metals industry

    Water is essential component in the mining and steel industries. The main needs under this aspect are optimizing the management of the resources, improving productivity by treating available water for specific production process requirements and managing environmental risks by treating contaminated pond and underground mine water to remove suspended solids and in particular heavy metals (SS), arsenic and other contaminants for safe discharge into sensitive environment.

    Water treatment solutions for the mining & metallurgy industry

    Contaminated mine water is generated when rock containing sulphidic minerals is exposed to water and oxygen, resulting in the production of acidity and high concentrations of metals and sulphate in the water. Mine drainage, process water and storm water associated with industrial activities are the main types of water produced in mining operation. The two primary aims of the treatment of contaminated mine water are to neutralize acidity and removal metals. Lenntech provides sustainable complete water treatment solutions for mining industry considering a wide range of technologies and strategies.

    Recycling and processing of shredder heavy fraction

    Since 1991, the bi-directional dense medium separation technology for the recycling of automobile and industrial wastes is being used. For many years a principle client in this regard has been the Group Galloo.  Group Galloo owns currently 50% of the AD REM shares. At first the Galloo staff was not convinced that a carrot separator could compete with the classical dense medium separators on the market at that time. So they set up a trial on +12 mm automobile shredder residue, running half of the test material through a conventional drum and the other half through this modified bi-directional carrot separator.

    EDXRF spectrometers for pharmaceutical industry

    The pharmaceutical industry is one of the most regulated industries. Contaminants in drug products are examined throughout the manufacturing process, since their presence affects drug stability, behaviour and toxicity. Therefore, regulatory bodies such as the European Medicines Agency (EMEA) and the American Food and Drug Administration (FDA) strictly enforce continuous and ongoing analysis of organic or inorganic impurities from raw materials, excipients and Active Pharmaceutical Ingredients (API) through intermediates of drug products and packaging.

    Determination of heavy metals in food

    This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.

    The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA spectrometer. The concentration of the elements is determined from the integrated analytical signal and is calculated using a preset calibration graph. The samples of food products are digested prior to analysis in accordance with standard methods.
