Are You Maintaining Your Demister Pad Correctly? Uncover Best Practices for Peak Performance

Maintaining your demister pad properly is vital for any application. The frequency of your maintenance will largely depend on how and where your demister pad is being used. In more grueling applications, like a grease trap, where solids are getting trapped in the demister pad, you must schedule regular maintenance to ensure that your demister pad is clean and works efficiently. In less strenuous applications, like an air scrubber, where the demister pad is being used to remove water droplets and small particles from the air, scheduled maintenance should be less frequent.  

Why is demister pad maintenance so essential? 

Regularly scheduled maintenance on your demister pads is extremely important. Not only does regular maintenance help extend the lifespan of your pad, but it also helps prevent problems such as reduced separation efficiency and plugging. Plugging, or fouling, is caused by built-up solids in your demister pad. A plugged pad can lead to excessive pressure drop and impact the demister pad’s performance. Regular cleaning and maintenance can help reduce plugging, reducing the risk of excessive pressure drop and performance issues.  

Cleaning your demister pad 

Several cleaning techniques  can be used to help maintain your demister pad. Some of these include spraying the demister pad with a cleaning liquid, boiling the demister pad, soaking the demister pad, or passing steam through the pad. The cleaning method, much like the frequency of your maintenance, will largely depend on your application. In less stringent applications where solids are not plugging your demister pad, using a cleaning liquid or boiling it may be enough to clean it properly. Heavier cleaning methods may be required in more stringent applications where solids are plugging your demister pad. If you are experiencing frequent plugging with your demister pad, despite routine cleaning and maintenance, a more economical decision could be to replace your demister pad more often. Replacing your demister pad also helps ensure your pad maintains the correct shape, size, pressure drop, and performance needed for your application.
