Composting of aged reed bed biosolids for beneficial reuse: a case study in New Jersey, USA
No full textReed beds with Phragmites australis (common reed) have been utilized to decrease the water, nutrient and volatile solids content of sewage sludge. An efficient disposal/reuse option was sought for reed bed biosolids accumulated over a 15 year period at a wastewater treatment facility in New Jersey, USA. The study facility had 14 reed beds, each with 1000 wet tons capacity, which were full, and so the solids needed to be removed. Because P. australis is considered an invasive species in New Jersey and several other states in the United States, disposal or reuse of solids containing this plant is regulated. Composting was examined as a potential treatment for destroying the plant’s reproductive rhizomes. The high temperatures achieved during composting were also tested to determine if regulatory criteria for pathogen reduction could be met, making the composted product suitable for unrestricted land application. Preliminary studies indicated the sludge had stabilized to the point where self-heating did not occur. Among the carbon amendments tested in the laboratory to stimulate compositing activity, Phragmites above ground biomass was determined to be most suitable. In a field test, Phragmites above ground biomass was mixed with reed bed biosolids at a 1:2 (w/w) ratio. The temperatures achieved resulted in complete mortality of Phragmites rhizomes. In laboratory tests, rhizomes placed in a drying oven at 50ºC for 24 hours, or 55ºC for 12 hours, showed 100% plant mortality. However, under field conditions pile temperatures could not be maintained long enough for the sludge to meet the USEPA 503 biosolids time-temperature pathogen rule requirements for unrestricted land application, even though sample fecal coliform counts did meet regulatory limits.Peer reviewed

Peter F. Dumont, CAE
No full textPeter F. Dumont’s career of more than 30 years in aviation ranges from his beginnings as a U.S. Navy air traffic controller, to Chief Operating Officer (COO) of the North American sector of a $3 billion defense contracting services company, and now as President and Chief Executive Officer (CEO) of the Air Traffic Control Association (ATCA).
After retiring from the Navy, Mr. Dumont began his private sector career with Serco, Inc., where he served as Vice President of Aviation and later COO. During his tenure, he oversaw multiple lines of business. His responsibilities included airport management contracts, air traffic control (ATC), ATC equipment installation, meteorology, weather observation, ATC engineering, control tower fabrication and installation, air traffic management (ATM), labor relations, business development, and a number of non-aviation related contracts and corporate management functions.
A recognized expert in the field of aviation, Mr. Dumont has been published in a number of ATM-related articles and has provided numerous interviews. He is regularly requested to deliver keynote addresses at aviation events and appear on discussion panels.
Today, as President and CEO of ATCA, Mr. Dumont serves a membership of over 3000 in all aspects of the ATC/ATM community. He interacts and collaborates daily with Fortune 500 companies as well as government executives to develop strategy and policy for the future of ATC/ATM. In addition to sitting on several boards of directors, Mr. Dumont represents ATCA on the Policy Board of the U.S. Contract Tower Association (USCTA), and is the newest member of RTCA’s NextGen Advisory Committee. He is also a past president of the Aero Club of Washington, and a former Co-Chair of the Institute Management Council (IMC) supporting the Federal Aviation Administration (FAA).
Mr. Dumont holds a Bachelor of Science in Professional Aeronautics and Master of Science in Aviation/Aerospace Management, both from Embry-Riddle Aeronautical University.https://commons.erau.edu/faa-uas-bios/1033/thumbnail.jp
