• Abstract:
  The Louisiana Department of Transportation and Development has long been interested in low maintenance waste treatment systems that can be used to treat small flows in situations where skilled operators are not available. The purpose of this project was to develop design and operating data for a rock filter (formerly rock-plant or rock-reed, filter) to treat high strength wastewater at an interstate rest area. Data have been collected over an eight-year period regarding removal of biochemical oxygen demand (BOD), total suspended solids (TSS), and ammonia. Granite rock media as well as a synthetic media have been evaluated for removal efficiency and ease of construction. The system described herein has been shown to be highly robust with respect to flowrate and waste strength. The synthetic media functions as well or better than granite media and is far easier to place and move when necessary.
