Wastewater treatment for the metallurgic industry

by Aguambiente     based in La Cistérniga, SPAIN

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.

Laser & Plasma Cutting

by DiversiTech     based in Montreal, QUEBEC (CANADA)

Laser & Plasma Cutting fumes are Unbreathable. Using laser or plasma cutting equipment on either metals or plastics introduces several known carcinogens, such as fused silica and ethyl acrylate, into the air. Occupational Health and Safety organizations recommend reducing personal exposure to the lowest level feasible. Hand held plasma cutting provides metalworkers with a quick and fast way to cut large sheets of metal material. However, plasma and oxy cutting generate a large amount of sparks, slag and fume which can contain different pollutants depending on the type of material being cut. Diversitech's line of downdraft tables incorporating the plasma cutting kit are designed to extinguish the sparks and slag, using heavy duty steel bar grating and a gravel filled baffle tray while the blower pulls away all of the toxic plasma cutting fumes. When considering how to capture and filter the fumes generated from large CNC plasma cutting and laser cutting machines, a large central dust

Metal Precipitation

by Graus Chemicals, LLC     based in Glendale, ARIZONA (USA)

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.

International testing for biofuels

by Metrohm AG     based in Herisau, SWITZERLAND

Sustainable use of biofuels requires reliable and precise analytical methods throughout – from the choice of raw materials through to process optimization and on to the compliant final product. As a leading manufacturer of instruments for chemical analysis, we are quite aware of these challenges.

Coal Combustion Residuals Disposal for Power Plants

by CETCO     based in Hoffman Estates, ILLINOIS (USA)

Coal combustion residuals (CCR) are generated during the power generation process and can include fly ash, bottom ash, boilerslag, and flue gas desulfurization (FGD) residuals. CCRs contain trace concentrations of heavy metals and therefore cannot be dumped or stored where rainwater can leach the metals. Liner systems can be used to contain the coal combustion by-products and protect them from leaching into the environment.

Quantitative Analysis of Steel Using Laser Induced Breakdown Spectroscopy (LIBS)

by Applied Spectra, Inc.     based in Fremont, CALIFORNIA (USA)

For steel analysis, LIBS is ideal for rapid QC (quantitative analysis and detection of contaminants) for raw materials in production, and to check the elemental composition of finished products. LIBS also offers the ability to analyze slag samples that can lead to the recovery of precious metals lost in the steel production process.

Evaporators technology for mining & primary metals industries

by EVALED - Veolia Water Technologies     based in Zoppola (PN), ITALY

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 filtration with UV purification for healthcare

by Waterlogic International Ltd     based in Basingstoke, UNITED KINGDOM

When hygiene is a matter of life and death and purity is premium, only Waterlogic is good enough. Tap water or traditional hospital water fountains can contain contaminants including pathogens such as Pseudomonas, Legionella, Streptococcus, and E. Coli. Is that safe? You don’t think so and neither do we. When it comes to healthcare, water quality must be of paramount importance.

Recycling and processing of shredder heavy fraction

by AD REM N.V. (Valtech Group)     based in Menen, BELGIUM

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.

Gas monitoring instruments and systems for nickel refining

by Gasmet Technologies Oy     based in Helsinki, FINLAND

The mining industry uses chemicals as ‘flotation’ agents in the recovery of sulphide minerals containing metallic elements (e.g., copper, nickel, silver, gold) from ore slurries. Sodium ethyl xanthate (SEX) is one of most common flotation agents, and it decomposes to form ethanol, carbon disulfide CS2, and Carbonyl Sulfide COS. These harmful gaseous compounds must be monitored from the indoor air at the enriching plant.

Water Treatment Solutions for Turbidity Removal

by Adedge Water Technologies, LLC     based in Buford, GEORGIA (US) (USA)

Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.

Water Treatment for Industrial Process

by Adedge Water Technologies, LLC     based in Buford, GEORGIA (US) (USA)

Among the various industrial treatment options available for heavy metal reduction, few are simple, proven, affordable, and reliable as the selective adsorption treatment technology offered by AdEdge Technologies. AdEdge provides a line of pre-engineered, packaged industrial wastewater treatment systems designed for removal of heavy metals from groundwater and industrial wastewater using a variety of adsorption media technologies.

Controlled Atmosphere Ovens for Process Industry

by Systech Instruments Ltd     based in Thame, UNITED KINGDOM

Contact lens controlled atmosphere ovens are used in applications where a specialised environment is required within the oven to achieve a high quality of contact lens. Typically the controlled environment will have a high percentage of nitrogen, and almost no oxygen (inert). The oxygen will need to be measured accurately, whilst the Nitrogen is controlled and regulated, in order to maximise production efficiencies and optimise product quality. Systech Illinois` nitrosave oxygen control system has the ability to perform both of these functions, achieving the ideal oven & heating/curing environment. Systech’s nitrogen control and oxygen analyzers are currently used by a number of leading contact lens manufacturers.
