Orlando Exploring Odor Control Options

Hazen and Sawyer will Examine Effectiveness, Efficiency, and Worker Safety

The Water Conserv II WRF utilizes several types of odor control systems. The 2-Stage Packed Tower odor control system has the capability of adding bleach, acid, or caustic solutions to treat the odorous air generated in the Sludge Press Facility.

The Bioway Tower odor control system utilizes a biological media to treat odors generated at the Sludge Thickening Building.

Several of the City’s major lift stations utilize on-site odor control systems. Lift Station No. 45 has a Quad Tower that uses caustic soda to strip odorous compounds from air exhausted from the wet well.

(HOLLYWOOD, FL – October 4, 2010) – The City of Orlando (Florida) has retained Hazen and Sawyer to provide on-going consulting engineering services for odor control projects for the City’s water reclamation facilities, wastewater pumping stations, and wastewater collection sewers and force mains. The project objective is to ensure that the City-operated wastewater facilities do not adversely affect the surrounding community by the emission of unpleasant odors.

This contract will be managed from Hazen and Sawyer’s local Orlando office which will be responsible for a multitude of tasks such as evaluating the applicability or operational efficiency of the various odor control systems, technologies, and strategies currently in use. Findings may result in making recommendations for system improvements or complete system replacements in order to optimize performance and minimize costs.

Hazen and Sawyer is also tasked with evaluating innovative odor control technologies and performing pilot tests for the purpose of providing alternative, cost-effective odor control systems and ensuring worker safety. Other types of services that may be provided under this contract include preparing design criteria for odor control projects meeting all of the City’s design specifications and standards, training City staff associated with odor control systems, evaluating the needs for odor control at the City wastewater pumping stations, and providing services associated with the design, permitting, bidding, constructing, and the start-up of odor control systems.

The City of Orlando owns and operates three water reclamation facilities, approximately 200 wastewater pumping stations, wastewater force mains, and several hundred miles of sanitary sewers ranging from 8 inches to 96 inches in diameter.

Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
