A horizontal open scrubber made of stainless steel. This scrubber consists of a rectangular housing with rectifiers, three washing sections with integrated washing liquid collection and droplet separators. The washing sections are equipped with an access hatch. The housing is equipped with connection cones to a pipe diameter of Ø 630 mm. The connection cone at the gas entrance is also equipped with an inspection hatch.

The scrubber is constructed, seen in flow direction, from the following sections:
- Caustic soda (NaOH) section, alkaline washing section with caustic soda solution, for removing the acid forming components and fats.
- Droplet separator, for preventing contamination of washing water of the sodium hypochlorite washing section
- Sodium hypochlorite (NaOCl) section, oxidative washing section with sodium hypochlorite solution, for washing out the odor components and any fumes from the caustic soda wash section.
- Droplet separator, for preventing contamination of washing water from the neutral washing section.
- Neutral section, washing section with clean washing water, for a final capture of water-soluble gas particles and any fumes from the sodium hypochlorite washing section.
