BACKGROUND:
The Water Resources Department (Department) currently operates and maintains over 145 lift stations for the City of Ocala (City). Due to the City's varied topography, achieving a fully gravity-based collection system is not feasible. As a result, the lift stations are strategically placed to transport wastewater from the collection system to the treatment facilities. Some of these are designated as master stations, receiving flow from multiple upstream stations. This configuration can lead to odor issues, which often prompt complaints from residents. To address these concerns, the Department employs a range of mitigation strategies, including chemical dosing programs, permanent odor scrubbers, mulch beds, and other available technologies.
In April 2025, the Department received approval to conduct a 30-day trial of a mixing aerator with ozone technology at two of our most critical pump stations. The TITUS Twister Mixing Aerator with Ozone Enhancement offers a chemical-free, safe, and highly effective solution for addressing severe odor issues in wastewater infrastructure.
This system is engineered to deliver ozone directly into the wastewater, targeting hydrogen sulfide gases, bacteria, pathogens, and odors at their source. In addition to odor control, the TITUS Twister enhances mixing, increases dissolved oxygen levels, and mechanically breaks down fats, oils, and grease (FOG), making them more bioavailable. The result is a healthier wastewater environment with measurable reductions or even elimination of odors, corrosion, and FOG accumulation.
