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.

The MDSJ Clean Air Technology tray scrubber is a versatile, low-pressure scrubber suitable for a wide range of applications with highly efficient dust capture. The MDSJ tray scrubber is also suitable for the extraction of gases and vapours such as SO2, HF, HCI, NH3 and CI2 and for the removal of SO2.
The scrubber can be equipped with a perforated turbulent contact tray or a controlled tray. The perforated type tray contains a large number of holes. The controlled tray is similar to a normal tray scrubber but has special diverters positioned above each hole. The diverters increase the dust collection efficiency because the dust directly impacts the submerged target, which is then washed away by the flowing liquid.
Depending on the application requirements, several types of trays and one or more stages can be incorporated into the MDSJ tray. The scrubber can be used with recycled liquids containing 2% solids. During operation, the dirty gas enters the bottom of the scrubber and passes through the holes in the tray. The washing liquid passes into the upper contact stage and flows through the tray. The gas absorbs the liquid, which creates a dust retention and a special gas/liquid mixture. The cleaned gas then passes through the mist eliminator and out the top of the unit to the atmosphere.
MDSJ Turbulent Contact Tray Scrubbers can be made of carbon steel, stainless steel, special alloys and plastics. Units are available with capacities ranging from 1000 to 400 thousand m3. The scrubber can handle recycled liquids containing 2% solids. During operation, dirty gas enters the bottom of the scrubber and passes through the holes in the tray.
The cleaned gas then passes through the mist eliminator and out the top of the unit to the atmosphere.
