Wet Scrubber Maintenance Checklist: Tips to Maximize Efficiency and Lifespan
Wet scrubbers are vital in industrial air pollution control, effectively removing dust, fumes, and harmful gases. However, like any equipment, their performance and lifespan depend on proper care. Regular maintenance ensures that the scrubber operates efficiently, prevents costly breakdowns, and complies with environmental regulations.
This checklist highlights the essential wet scrubber maintenance practices every industry should follow.
With advanced wet scrubber technology, industries achieve compliance, sustainability, and enhanced operational safety.

Wet Scrubber Maintenance Checklist
1. Inspect Nozzles and Spray Systems
Check for clogging, corrosion, or uneven spray patterns.
Clean or replace nozzles to maintain proper liquid distribution.
2. Check Liquid Flow Rate & Pressure
Ensure the scrubbing liquid is flowing at the correct rate.
Monitor pressure gauges for abnormalities.
3. Examine Pumps and Motors
Inspect seals, bearings, and lubrication.
Replace worn-out parts to avoid system shutdowns.
4. Monitor pH and Chemical Balance
Regularly test the scrubbing solution’s pH.
Maintain chemical dosing (e.g., lime, caustic soda) for optimal neutralization of gases.
5. Clean Mist Eliminators & Demisters
Remove buildup of particulates and liquid carryover.
Wash or replace pads as needed.
6. Inspect Ductwork and Piping
Check for leaks, blockages, and corrosion.
Ensure connections are airtight.
7. Examine Structural Components
Inspect scrubber shell, supports, and linings for signs of wear.
Repair cracks or corrosion to prevent system failure.
8. Check Drainage and Sludge Handling
Ensure proper removal of slurry, sludge, or captured particulates.
Prevent clogging in drains and sumps.
9. Monitor Airflow & Pressure Drop
Measure pressure drop across the scrubber.
Unusual increases may indicate blockages or fouling.
10. Regular Calibration & Record Keeping
Calibrate sensors and gauges periodically.
Maintain logs of inspections, repairs, and performance data for predictive maintenance.
Conclusion
A well-maintained wet scrubber not only ensures maximum pollutant removal efficiency but also reduces downtime, operational costs, and regulatory risks. By following a systematic maintenance checklist, industries can significantly extend the lifespan of their wet scrubbers while maintaining clean and safe air emissions.
