The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals. This session will include the following presentation: Successful High Density Sludge (HDS) Treatment Plant Design for Acid Mine Drainage The high density sludge (HDS) process was developed by Bethlehem Steel in the 1960s in response to high sludge disposal costs following lime neutralization treatment of acid mine drainage (AMD). Since then it has become the preeminent AMD treatment process not only for significantly lower sludge production but also for its ability to provide more stable treatment over a wide range of AMD chemistries. However, even after nearly 50 years why and how it works, and what's needed for effective design of an HDS treatment plant, is not widely known. This presentation describes the fundamentals of HDS and key information needed for successful design. To view this archive online or download the slides associated with this seminar, please visit
