Assessment of lagoon odor emissions before and after installation of solar-powered circulators; Myrtle Beach water reclamation facility
The City of Myrtle Beach operates a large wastewater treatment lagoon in parallel to its mechanical treatment plant located off Mr. Joe White Avenue in Myrtle Beach, South Carolina. The lagoon system occupies an area of over 45 acres. The large, odor-emitting surface area, combined with encroaching development, has resulted in complaints against the City regarding odor emissions from the lagoons.
In June of 2004, Bowker & Associates, Inc., a firm specializing in the control of odors from waste handling facilities, was retained by B.P. Barber and Associates, Inc. (BPB) the City’s wastewater consultant, to evaluate methods of mitigating odor impacts from the lagoons. A final report issued in January, 2005, recommended dredging of Cells 1, 2, and 3 and replacing the existing diffused aeration system serving these three cells with solar-powered circulators. The City installed the solar-powered circulators in January of 2005, and has attempted to pump solids from Cell 1 to reduce the volume of settled sludge. Follow-up testing was conducted in April, June, and August, 2005 to measure the lagoon odor emissions and assess whether the solar-powered circulators were achieving the desired goal of odor reduction.
