Filter cake is a common byproduct of industrial chemical and physical waste water treatment, soil washing and other chemical processes. These wastes are frequently produced in large quantities and contain a variety of contaminants like hydrocarbons, solvents and mercury. The disposal of these wastes can be challenging and costly due to the high moisture content and often high degree of contamination accumulated in the filter cake.
Our VacuDry® technology allows recovering valuable resources such as oil in these wastes while also reducing the volume significantly. After treatment there is no more incineration required and the solids can be reused for mountain backfill or disposed off at more favorable landfill classes.
Benefits of VacuDry®:
- Low energy consumption through efficient heat transfer & vacuum
- Recovery of valuables including hydrocarbons, solvents or mercury
- Moisture removal for significant volume reduction
- High flexibility regarding different types of waste streams
- Prevention of incineration and unnecessary CO2 emissions
