Advantages
Safely handles combustible dust.
In applications involving combustible dust, a wet scrubber eliminates the risk of an explosion in the scrubber. Dry systems require safety equipment to avoid dust related explosions. That, along with the ongoing maintenance for dry systems, adds to the cost.
Saves space.
Without the ductwork needed for baghouses and cartridge collectors, wet scrubbers consume less space in the plant allowing for more flexibility in the site location.
Handles sticky materials
In dry systems, sticky material can quickly clog filters increasing the cost of labor and replacement filters. Wet scrubbers have no filters.
Removes unwanted soluble gases.
Wet scrubbers can collect both gases and particulate matter, as well removing water-soluble odors. In contrast, dry dust collection systems do not remove gases and odors.
Handles high temperature and moisture
Wet scrubbers have no temperature limits or condensation problems like those that can occur in baghouses.
No secondary dust sources
Once collected, particulate cannot escape from hoppers or during transport.
Minimize maintenance.
The only regular maintenance required is to regularly change the scrubber water. The frequency depends on the CFM of the system, the amount of particulate in the influent gas, and the PPM targets required of the effluent gas.
