    Evaporation 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.

    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.

    Recycling of Incinerator Slag

    Incinerator slag mainly consists of mineral components, metal scrap and other unburnt materials. With our separation systems we are able to treat both the untreated ash as well as the mixed and contaminated metal fraction. Out of both fraction we can recover a clean aluminum and a heavy metal fraction.

    Waste recovery for energy & utilities

    In order to stay competitive and to be seen as being environmentally responsible, energy and utility companies are always looking for alternative routes to generate power. One method of doing this is by leveraging waste to energy incineration plants linked to the processing municipal solid waste. During this incineration process, APC residues, which are a mixture of fly ash, organic pollutants (including dioxins and furans), are generated and are classified as hazardous waste and have a detrimental environmental impact. This fly ash is subject to Air Pollution Control as it is contaminated with extremely high concentrations of heavy metals and toxic compounds like dioxins, linked to cancer and other health problems. Tetronics offers valuable waste recovery plants that can eliminate the hazardous element within the fly ash while generating an inert building aggregate with the remaining material.

    Industrial Solution for gasification & synthetic gas

    Gasification and synthetic gas production from various waste products are becoming increasingly important energy recovery technologies. Often, the synthetic gas contains various hazardous contaminants including H2S, HCl and other acids, heavy metals, and tars. The gas requires cleaning before it is introduced in the engine or boiler. Most of these processes generate significant concentration of tars. The tars can vary from very low molecular weight to large and complex chains.

    Industrial wastewater solutions for vibratory grinding wastewater

    Using innovative recycling technologies in vibratory grinding processes. Rinse water from vibratory grinding processes ca be contaminated with heavy metals, oils and, depending on the process, even a variety of chemicals. It cannot be discharged into the public sewer system, and usually requires to be disposed of with specialized waste management companies expensivly. But there are alternatives: Vacuum distillation with VACUDEST evaporators is an economical, resource-friendly method for treating this industrial wastewater. It conditions the vibratory grinding wastewater in such a way that it can be reused in the process.

  • Air pollution control (APC) equipments for waste incineration

    Waste incineration is a complex area. The mix of waste, moisture content, temperature of the waste, surrounding air and a variety of other factors interact and affect which residues are formed. Combustion entails often a gas consisting of heavy metals, sulfur oxides, chlorides, dioxins, etc. It is extremely important with a proper handling of the gas and the task often requires a mixture of wet and semi-dry treatment. EnviBAT offers equipment that brings particle levels down to extremely low levels, which guarantees a total separation of dioxins and wet purification that separates contaminants found in the gas phase.
