Chemischer Wäscher

The Haarslev Chemical Scrubber removes VOC-related odours from meat and fish by-product processing by washing process air with water and carefully selected reagents. This absorbs acidic and basic gases that include H₂S and NH₃, and oxidises other odorous organic compounds. Each system is engineered to match the specific airflow, gas composition and space constraints, with single or multi-stage setups designed for reliable, low-cost odour removal.

Value at a glance

Built for
performance

  • 01
    Handles large air volumes, typically 6–8 times the building’s air volume per hour, removing VOCs, acids and bases that create odours during meat and fish by-product processing.
  • 02
    Chemical washing absorbs H₂S and NH₃, and oxidises VOCs that include amines, aldehydes, mercaptans and organic sulphides. This ensures reliable odour reduction even with complex gas mixtures.
  • 03
    Available as single or multi-stage systems with corrosion-resistant towers, reagent dosing and integrated recirculation pumps for stable 24/7 odour-control performance.
  • 04
    Compact footprint allows easy installation outdoors or next to processing buildings. This makes them ideal where biofilters or thermal oxidation units are not feasible.
  • 05
    Very low maintenance requirements thanks to corrosion-proof materials, efficient washing stages, blade-style mist eliminators and a simple, controlled process design.
