When it comes to Odor Control and Air Emission scrubbers, you're either pleased with how yours is working or highly frustrated with how it isn't.

While wet scrubbers are powerful devices that can reduce various harmful air pollutants and exhaust gases, not all are created equal. An operator's most common problem with a scrubber is a lack of performance. The following are some main reasons why your scrubber may not work correctly.

When it comes to designing a wet scrubber, different manufacturers have different design standards. Creating a device that can handle high throughput with reduced cleaning cycles. Others will develop a scrubber concentrating on the maximum removal of pollutants.

The wet scrubber that you purchase should be based on your specific needs. If you buy a scrubber not designed for your particular application, you're setting yourself up for problems.

Some factors will determine how well your scrubber will perform. Including the gas flow rate, gas pressure, the type of media used, and the design of the scrubber itself. If your wet scrubber design cannot handle your application's specific requirements, you'll experience reduced performance and increased downtime.

Faulty installation of the scrubber.

If your scrubber is not installed correctly, it will not perform properly. A poorly executed installation can cause a wide variety of issues.

The most common problem is channeling, which causes a low-pressure drop across the scrubber. The most common cause of this issue immediately after an installation is an out-of-level scrubber tower, followed by the improper placement of the media bed. A poor installation will cause reduced performance and allow odor or chemical breakthrough from the exhaust of the scrubber. The incorrect type of media in a scrubber can also cause a reduction in performance. Upon discovering a low-pressure drop, the scrubber should be inspected to ensure the installation was done properly and that the media bed is correctly sized and placed within the scrubber for its specific application. Remember, one size does not fit all regarding odor control and air emissions scrubbers!

First, make sure you hire a reputable engineering firm or work directly with a manufacturing company that has professional engineers on staff that have experience and specialize in wet scrubber design and installation. It's also essential to review the manufacturer's installation manual and follow the instructions.
