Abstract
  • Decentralized or "on-site" wastewater treatment systems offer a number of advantages over conventional centralized systems, including reduced capital costs, adaptability, and ease of implementation for water reuse. While the ability of these systems to remove traditional wastewater constituents is well known, their ability to address contaminants of emerging environmental and public health concern, such as pharmaceuticals and personal care products, is less established. This report explores the effects of various design and operating parameters on emerging contaminant removal, with a focus on the use of batch studies to identify which removal mechanisms are most relevant. The results of an initial batch study, using wastewater from the Jordan Lake Business Park (Apex, NC), suggest that mixed media consisting of gravel, Stalite, and sand were more effective than sand alone at removing five selected contaminants from the bulk solution.
