FGM - Vertical Single-Stage Scrubber Tower Scrubber
Our single stage scrubber tower scrubbers are the simplest solution to well defined air pollution problems. Their typical use is the abatement of acid gases, saline mists and the capture of soluble VOCs (Volatile Organic Compounds). The single stage scrubber tower is composed of a single bed of fillers. Consequently, the abatement efficiency will be high if the polluted gas flow is well defined and characterized.
Certainly the single-stage scrubber supports few fine dusts, in the quantity in which the washing solution can retain them. Consequently, this type of equipment is not suitable for treating gases with high concentration dust. Therefore we recommend other pre-scrubber systems such as the Venturi Jet crubber or dry technologies (FM bag filters and FC cartridge filters).
Built to customer specifications, the standard single-stage scrubber is completely made from Polypropylene sheet.
There are two modes of operation:
- Co-current flow: air and washing liquid pass through the fill from top to bottom
- Counter-current flow: polluted air flows through the scrubber from bottom to top, while washing liquid from top to bottom.
Ultimately, for a good use of the single-stage scrubber we suggest the dosage of targeted chemical products
- Sulfuric Acid: for the reduction of Ammonia and Amines
- Caustic soda: for the reduction of organic and inorganic acids
- Sodium hypochlorite: can be added to increase the oxidizing power in addition to the two products
