Industrial Wet Scrubbers
Industrial Wet Scrubbers · Since 1938
Engineering solutions for the most industrial polluted gas streams.
Six proven scrubber architectures — from patented Dynamic UW systems to high-energy venturis and marble bed absorbers — delivering >99% collection efficiency on sub-micron particulate, FGD, and acid gas removal.
The Platform
One engineering partner. Six wet scrubber technologies.
Wet scrubbing is not one technology — it’s a family of them. The right architecture depends on particle size distribution, gas chemistry, pressure drop budget, water availability, and the corrosive reality of your flue stream.
Ducon Environmental designs and manufactures every scrubber category in active industrial use today, including two patented dynamic designs (UW-3 and UW-4) engineered for heavy dust loads and tight footprints. Below: the complete lineup, with the operating principles and performance envelopes that determine which one fits your process.
Systems · 01–06
The six wet scrubber systems.
Each system is matched to specific gas chemistry, particulate profile, and operating economics. Patented Ducon designs are flagged.
Venturi Wet Scrubber
High-energy sub-micron capture.
Converging–throat–diverging geometry accelerates gas into a high-velocity zone where scrubbing liquid is sheared into micro-droplets. Ducon’s proprietary “wetted wall” weir inlet eliminates spray nozzles entirely — no plugging, direct slurry recycle. Includes the high-energy Oriclone VVO variant.
Ventri-Rod Deck Scrubber A5
VVO rod-array FGD & particulate.
Forces gas through a horizontal array of parallel, spaced rod-like elements rather than a traditional cone. Closely spaced rods reduce cross-section, accelerate gas, and create an intense scrubbing zone. Low-energy single or multistage configurations available — compact footprint for dual-duty FGD plus fine dust capture.
Dynamic UW-3 Wet Scrubber
Unitized, self-cleaning wet fan.
Patented compact dynamic scrubber with an integral, self-cleaning wet fan that simultaneously moves the air and drives the scrubbing action. Engineered for industrial environments where floor space is at a premium. Very low water consumption with rugged construction targeting near-zero maintenance.
Dynamic UW-4 Wet Scrubber
3-stage, non-plugging, heavy-load.
Patented three-stage dynamic scrubber built for heavy dust loads and abrasive materials. Two-stage pre-cleaner removes up to 90% of heavy dust before reaching the fan. Wet-side fan is constantly flushed — protected from dry abrasion and condensation. Medium pressure drop, very low water rate (2–3 gal per 1,000 saturated ACFM).
Spray Tower Wet Scrubber (Packed Tower / CAT)
Chemical absorption of toxic gases.
Counterflow column — gas upward, scrubbing liquid downward. No internal packing; mass transfer is generated entirely by Ducon’s proprietary non-plugging spray nozzles. For dry FGD, the DRX-25 two-fluid nozzle atomizes feed slurry in the spray reactor. Handles SO₂, HCl, H₂S, NOₓ, NH₃, and VOCs.
Marble Bed Wet Scrubber
Mobile-bed FGD + particulate.
Gas forces upward through a packed bed of lightweight glass spheres; alkaline scrubbing liquid (lime or limestone slurry) flows over them. The gas tumbles the marbles into a constant, mobile-bed agitation — preventing settling, flushing captured solids, and maintaining exceptional mass transfer for SO₂ absorption.
Selection Matrix
Which scrubber fits your gas stream?
Fast side-by-side on the dimensions that drive scrubber selection: particle size, pressure drop, water use, and primary duty.
| System | Primary Duty | Efficiency | Pressure Drop | L/G Ratio | Best Application |
|---|---|---|---|---|---|
| Venturi | Sub-micron particulate & fumes | > 99% sub-micron | 10–15 in. W.G. or more | 5 – 15 gal / 1,000 ACFM | Fine dust, slurry recycle, high-efficiency |
| Ventri-Rod A5 | Particulate + SO₂ / FGD | PM >99% · SO₂ 99.5% | Low-energy | L/G 10 – 70 | Dual-duty FGD + PM, compact footprint |
| Dynamic UW-3 | Compact industrial dust | > 99% | Low (built-in fan) | Very low | Tight footprints, limited water supply |
| Dynamic UW-4 | Heavy / abrasive dust | >99% @ 1–2 µm | Medium (built-in fan) | 2 – 3 gal / 1,000 sACFM | Heavy, sticky, abrasive dust loads |
| Spray Tower | Acid / soluble gas absorption | up to 99.99% | 4 – 6 in. W.G. | L/G 15 – 60 | SO₂, HCl, H₂S, NOₓ, NH₃, VOCs |
| Marble Bed | FGD + simultaneous particulate | 99% acid gas · 99% PM | 10 – 15 in. W.G. | 6 – 15 L/m³ | SO₂ + fly ash, retrofit FGD |
