Abstract The Bachman Treatment Facility was built in Dallas, Texas, to provide physical-chemical treatment to those municipal wastewater flows that during periods of heavy precipitation exceed the capacity of a downstream interceptor. The treatments provided in the facility include the addition of waste lime sludge from a nearby water purification plant, flocculation, sedimentation, tube settling, and chlorination. The facility was operated primarily to determine the benefits that might be derived from the addition of potable water treatment plant waste sludges to these excess flows since unpublished laboratory work conducted elsewhere had indicated potential benefits in terms of better suspended solids and BOD5 removals than would result from sedimentation alone. The results showed no benefit from the addition of potable water treatment plant waste sludges to these artificial flows, but the few times the plant operated on genuinely occurring excess flows, possible benefits were observed.
