Our Challenge

To develop a pilot demonstration that will optimize an accurate odor control prediction for Rothsay's Moorefield facility.

Our Solution

Based on exceptional results of the pilot study which yielded total odor removal rates as high as 98%, a large 230,000 cfm fully intregrated Biofiltair biofilter was erected using an acid resistant concrete structure and a hollow core roof.  This five cell system, designed with expandable capabilities of up to 276,000 cfm, also operates with Biosorbens® permanent media.

Two banks, one of three cells and one of two are interconnected with a central air plenum to provide greater down flow configuration. Stainless Steel and FRP ducting as well as other internal components such as the five large VFD controlled fans were installed and tied into an advanced pressure sensing system to enable an instrumentation network for fill automatic control.

Our Success

The installation, constructed with a large pretreatment unit for homogenization of airflows, has exceeded all expectations. The system currently operates with 98% total odor removal efficiency.
