UG-Mat-Baghouse Fines | Recycled Materials Resource Center

Although most of the baghouse fines are returned to the asphalt mixing plant, some producers (probably less than 10 percent) with excess dust dispose of the dust by sluicing it to a settling pond or returning it to the quarry. (2) Where wet scrubbers are employed for dust control instead of baghouses, the washed fines are generally discarded.

The pond allows for coarse and fine grained sediments to settle out. Water then flows through a geotextile/sand filter located in the southeast corner of this pond and into a final settling pond ("Secondary Settling Pond"), which was built in February 2005. The purpose of this pond is to allow for further settling of fine sediments.
