What is a Wet Scrubber?

A wet scrubber is a multi-stage industrial air pollution control device that uses water or neutralizing chemical solutions to remove over 99.9% of acidic gases, heavy particulate matter, and odors from exhaust streams.

  • Working Principle: Dirty gas is driven through a washing tower where high-pressure liquid completely saturates and captures pollutants.
  • High Efficiency: Removes particulate matter and hazardous chemical gases at extreme temperatures where dry filter systems fail.
  • Gas & Odor Treatment: Highly effective for H₂S, NH₃, SO₂, and HCl neutralization in water treatment and chemical process plants.
  • Advantages: Non-clogging open structure, filterless design, low maintenance costs, and high durability under heavy industrial loads.

What are Wet Scrubbers?

MDSJ Wet Scrubbers use variety of technological configurations to remove particulates and acid gases from exhaust flue gas stream. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, and forcing it through a pool of liquid, or by some packing media or trays, so as to remove the pollutants. MDSJ Wet Scrubbers are designed to collect particulate matter and/or gaseous pollutants with over 99.99% efficiency and can achieve under 15 m gr/M3 emissions.MDSJ known for its patented dynamic wet scrubbers which include the Dynamic Wet Scrubbers. The MDSJ Dynamic Wet Scrubber is for use in applications involving heavy dust loads, and abrasive materials.
Where heavy dust loads and large particulate have to be removed The Multivane Centrifugal wet Scrubber is particularly suited for applications involving heavy dust loads and large particulate.

Where does it fit best?

  • Wet scrubbers are strong candidates where acid-gas removal and odor control must be handled together in the same process line.
  • They offer more flexible integration than dry systems when gas cooling and scrubbing must happen in sequence.
  • When dust loading and gas composition vary together, liquid-circuit and chemical control provide tighter operating control.

Selection criteria

  • Gas flow, temperature, humidity, and contaminant composition should be evaluated together.
  • Pressure drop, liquid consumption, pump load, and mist eliminator design shape the operating cost envelope.
  • Reaction chemistry, pH control, and blowdown handling should be defined early in the design phase.

Operation and maintenance notes

  • Nozzle fouling, pump-circuit stability, mist eliminator contamination, and corrosion points should be monitored routinely.
  • Liquid recirculation stability and chemical-dosing control are critical to sustained performance.
  • Installations without maintenance access planning typically increase downtime and service cost.

Frequently Asked Questions

Is a venturi scrubber the same as a wet scrubber?

A venturi scrubber is a high-energy sub-type within the wet-scrubber family. Wet scrubbers also include packed-bed, dynamic, and chemical-absorption layouts.

When should a wet scrubber be considered instead of a dry system?

Wet scrubbers become more suitable when gas-phase contaminants must be dissolved or neutralized, or when the stream carries high humidity or corrosive load.

What drives operating cost the most?

Pressure drop, pump duty, liquid consumption, chemical dosing, and maintenance access are the main cost drivers.

Quick Info

Gas and particulate removal can be handled in the same line
Easy process integration for corrosive or wet gas streams
Can be adapted with venturi, packed-bed, and chemical-absorption layouts
