heavy metals water Applications

  • Detection of specific heavy metal content in water

    Detection of heavy metal concentration in water, sea water, environmental waters and pre-treated waste water to low PPB levels using a hand held fluorimeter. Test results acquired within one minute. Technology uses DNAzyme based fluorimetric detection.

    Metal Precipitation

    When used as part of a wastewater treatment program, Remotox (calcium polysulfide) can effectively reduce and precipitate a wide range of heavy metals. This product has proven effective even when treating chelated and/or complexed metals. Its unique formulation also removes chromates and dichromates without preliminary reduction of the chromium to the trivalent state.

  • Wastewater treatment for the metallurgic industry

    Waste water in this sector has a high concentration of heavy metals, oils and products in decomposition. The oils and emulgents lead to foam production at the water treatment plants. The treatment of these oils is very important.

  • Evaporators technology for mining & primary metals industries

    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 heavy metals, arsenic and other contaminants for safe discharge into sensitive environment.

    Water analysis for municipal wastewater treatment

    Voltammetric determination of many heavy metals is also possible in municipal or industrial wastewater. On account of the usually high organic load the sample is usually mineralized by means of UV digestion.

    Pollutant Decontamination for the Wastewater Treatment Industry

    All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central Europe. They can be also used for a reduction of the content of heavy metals, nitrates and phosphates in the drinking water. Just these inorganic pollutants, which are hardly or expensively removed by standard technologies, are effectively removed by Fe(0) nanoparticles.

  • Water monitoring for laboratories

    Chemical purity of water is assessed for a wide variety of different chemicals depending on the type of water and applicable local legislation. 

    Chemical analysis of water can include testing for nitrogen compounds, dissolved heavy metals, and total and dissolved organic carbon.

    Common water monitoring applications include:

    • Determination of suspended solids in waterusing for example glass fiber filters.
    • Chemical analyses of for example heavy metals, dissolved organic carbons (DOC), and ions.
    • Microbiological analyses using membrane based microfiltration methods

  • Vacuum excavation solutions for locate underground utilities / soft dig / pot holing

    Vacuum excavation is fast becoming a best practice in the field of construction and site excavation. Why? Because it uses jets of air (air excavation) or water (hydro excavation) to loosen soil, instead of a heavy metal claw. After loosening, the soil is pulled out of the ground through an air vacuum hose to a debris tank for later disposal or back-filling. Using non-destructive technology can quickly, safely and economically excavate in areas inaccessible to conventional digging equipment like backhoes and trenchers.

  • Disposal wells treatment for oil and gas industry

    Treating the water being injected for disposal is not always considered by operators. This is likely costing you money in the long run. Removing iron, heavy metals, and treating out ammonia is a benefit to treating with MIOX’s mixed oxidant solution. While these are benefits of the technology, the most important is the elimination of bacteria which can cause Hydrogen Sulfide (H2S), corrosion pitting, poor injectivity and other problems, resulting in great well workover frequency. Treating injection wells does not need to be expensive, and can be treated as you inject.

  • Welding Fume Extraction

    Welding fumes & gases are Unbreathable. Nonetheless, welding is perhaps the most common industrial process and necessary anytime the joining of metals is required. Regardless of the welding equipment type or technology, the simple process of melting metal and filler materials creates poisonous fumes and gases. ? Different types of welding processes present unique challenges to adequately handle airborne fumes. Robotic welding equipment and other automated welding systems produce a high volume of welding fumes and sparks and need to captured by a heavy duty robotic welding hood. Moreover, manual stick welding typically produces a high volume of smoke and often requires a self-cleaning fume extractor to avoid overwhelming the filters.? Lighter duty applications like MIG welding generally produce less particulate and light-duty TIG welding generates the least amount of smoke. It is important to not only consider the type of welding process but also the work piece material in order to select the correct filtration media for your application. HEPA filters are recommended for stainless steel welding, Nanofiber filters for Aluminum and parts containing higher levels of Manganese. Polyester filters are appropriate where rust inhibitor, lubricants and coatings create an oily smoke as these filters can be washed in water. Diversitech offers a complete line of fume collection machines from compact welding fume extractors to central welding fume filtration systems. We specialize in engineered solutions and our engineering team is experienced in selecting the best equipment and filter media for your particular application. We can present you with detailed technical drawings demonstrating several potential layouts and solutions including costing, installation and start-up expenses. ??
