There are many types of sludge. They are as varied as the industries that produce them. Customized high-temperature processes are required to optimally treat different types of sludge and the specific impurities they contain. On top of that, it is important to ensure that no hazardous materials escape during processing. The high-temperature evaporators from our subsidiary AVA are able to handle all types of sludge. This includes drilling sludge from mining operations, volatile paint sludge and metal sludge generated in the metalworking industry. Temperatures of up to 650 °C can be achieved, making it possible to vaporize long-chain hydrocarbons.
Drilling sludge is made up of a mixture of soil and long-chain hydrocarbons. It is produced, for example, during geothermal drilling where diesel is used to cool the drills. Our turnkey, mobile systems consist of an evaporator from our subsidiary AVA (as the core component), the vacuum and condensation module and a product infeed and discharge unit. They can be used to treat drilling sludge on site. This reduces the cost of disposal and also means the treated sludge is available immediately for use as backfill.
Paint sludge contains solvents. This makes it highly flammable, explosive and therefore expensive to dispose of. Our turnkey systems, which consist of an evaporator produced by our subsidiary AVA (as the core component), the vacuum and condensation module and a product infeed and discharge unit, is able to effectively separate solvents from paint sludge. This not only minimizes the risk of explosion when further handling the sludge, but also lowers the cost for disposal in a landfill. Moreover, the solid residues can be used as refuse-derived fuels.
Metal sludge is produced in the metalworking industry, for example, during machining operations. Our turnkey system used in the processing of metal sludge, which consists of an evaporator from our subsidiary AVA as the core unit, can be used to recover and recycle valuable resources. This reduces production costs and benefits the environment, too.
