Abstract
Over the last several years, the Mount Holly Municipal Utilities Authority (MHMUA) in New Jersey has undergone an extensive expansion project. The treatment capacity of its existing wastewater treatment plant was increased, and a new 3 Mgd plant was constructed. As part of the expansion program, MHMUA incorporated an extensive odor management program to meet its NJ DEP permit requirements and to minimize the impact on nearby residents, businesses, and travelers.
MHMUA selected BioAir Solutions’ EcoFilter biotrickling filter technology as the desired odor control solution after an extensive review of the odor control products available on the market. The biotrickling filters use plastic, structured synthetic media that represents the latest in biotrickling filter technology, capable of removing both organic and inorganic odors. The EcoFilter technology combines the sustainability and low operating cost associated with biological treatment with the durability and acidresistance of synthetic material, which eliminates media maintenance and replacement cost.
The MHMUA project represents the largest biotrickling filter installation in the state of New Jersey. It consists of five biotrickling filters that are installed at various locations at the treatment plants, treating odors from sources such as the grit and screenings building, sludge storage tank, surge tank, rotary drum thickener, gravity thickener, drain pump station, screw conveyor, and headworks.
This paper provides an overview of the project along with performance data for the odor control systems installed at the various locations at the MHMUA wastewater treatment plants.
