Info

• Goals: Media Testing – To provide information for design (e.g., optimal media components, depths, and contact times) – To maximize the likelihood that filtration-based treatment controls will achieve desired level of performance in the most cost effective manner 14 These tests were conducted in conjunction with Dr. Shirley Clark at Penn State – Harrisburg and Geosystec, and sponsored by The Boeing Co.
Media Tests (cont’d) • Long-Term Column tests using actual stormwater: – Clogging, breakthrough, and removal – Effects of contact time and media depth on removal • Batch tests: – Media uptake capacity and removal kinetics – Aerobic and anaerobic effects on pollutant mass removed 15
