Bio filters
Prantner biological filters are used to treat waste gases with low concentrations of pollutants. For the efficient use of a biological filter, the following requirements must be met:
- The pollutant must be biologically degradable
- Concentration of max. 0.5 g/m³
- Adequate polarity of the substance (solubility)
- Easily adsorbed onto a filter mass
We have solutions for the following fields:
- Sewage/water works
- Smokeries
- Large scale animal rearing
- Animal carcass disposal
- Various industrial production processes
Process Principle
Prantner bio-filters are high-surface area filters either built as a single layer or in a multi-storey arrangement. The residence time in the bed is approximately 30 seconds. The filter mass is a special mixture of a biologically active material and an inert carrier substance. Apart from the filter bed, the units consist of a process air blower, temperature control, irrigation system (via nozzles) as well as the control system.
