Our first scrubber systems went into operation in 1988. Since then we have delivered a great many, chiefly for cleaning and/or condensing flue gases generated by the incineration of waste.

Combining several process stages in our patented multi-stage scrubbers reduces space requirements, and our integrated circulation tanks minimize energy consumption in the pump system.

Examples of process stages that can be combined in our scrubbers are:

- HCl removal
- SO2 removal
- Hg removal
- Flue gas condensation
- Dioxin absorption
- Wet electrostatic precipitators for particulate removal

Because gases from combustion and incineration processes are often extremely corrosive, our designs are constructed mainly from plastics, which provide equipment with very long service lives. The structure is made from GRP (glass reinforced plastic) and most of the internals (tower packing and droplet separator) from ADIOX® material. The ADIOX® material absorbs dioxins and also ensures no so-called memory-effect problems arise.

The scrubber systems are customized for each application, in principle without gas flow restrictions.


The illustration shows an exploded drawing of a typical multi-stage scrubber. The gas inlet is in the lower scrubber section, which also shows how the ADIOX® tower packing is placed on a support grid made from glass reinforced plastic. The center section shows how a circulation tank is integrated into the scrubber structure; a droplet separator is located centrally inside the circulation tank with a so-called combi-element collecting tray above to act as support grid for an additional tower packing section. The water spray system and the final droplet separator can be seen in the upper section.
