Thermophiles require oxygen - and lots of it - to thrive and consume excess food. But the exact amount of oxygen they need for optimum performance is not constant. It varies widely depending upon the stage the process may be in. Yet surprisingly, conventional ATAD systems disregard these variations, providing only a single rate of oxygen supply, an inflexibility that requires a cumbersome multi-reactor process to produce a single pathogen free batch.
For the first time you can precisely match oxygen delivery to oxygen demand, thanks to the revolutionary ThermAer process featuring a patented flexible-flow Jet Aeration System. You get all these benefits and more:
- Extremely high oxygen transfer efficiencies at low air/liquid ratio
- Thermal conservation with low air/liquid ratio
- Independent control of oxygen transfer and mixing
- Variable liquid and air flow for temperature control
- Higher shear mixing of viscous mixed liquor
- “Retrofitability” to virtually any basin/ tank geometry
Unlike conventional ATAD systems, ThermAer monitors and controls your process throughout the cycle. Using proprietary technology available only with ThermAer, truly aerobic conditions are maintained at all times. The benefits of this revolutionary concept over conventional ATAD systems have been proven through several years of full-scale operating experience:
- Optimized energy input
- More efficient mixing from the bottom up - providing the most effective mixing intensity for
- 3-4% solids mixed liquor
- Managed and controlled foam production
- Eliminating the release of reduced sulfur compounds which cause offensive odors
How It Works
Whether you are upgrading your present system or planning a new one, you can’t afford to overlook the exceptional benefits offered only by ThermAer:
Flexibility
ThermAer is easily adapted to optimize most existing or proposed design schemes, mechanical equipment and processes, including:
- Virtually any tank size and geometry
- Various thickening and/or dewatering equipment
- Unique site conditions and space considerations
- A wide variety of process flow schemes, including single or multiple reactors
Reliability
ThermAer has consistently met the most stringent demands for safety and reliable performance in the field. For example:
-
Flexible options for maintaining tight temperature control at all times. ThermAer’s advanced jet aeration technology allows variations in air flow, liquid pumping, or both
-
Optimum Foam Control through the stability of the aerobic process, and the unique foam cone. Overflow and adequate headspace in the reactor assure absolute foam management.
-
Safer, Easier, Less-Frequent Maintenance because there are no moving parts inside the basin
-
Optimum Pump Life thanks to ThermAer’s innovative process, allowing your pumps to meet precise aeration requirements at low speeds
• Consistent Process Performance since the thermophilic organisms are maintained in their ideal environment at all times, assuring they are always hearty and resilient
Simplicity
For all its sophistication, ThermAer requires very little attention and is remarkably easy to operate. Your operators can perform batch fill and draw with just a few hours a day of their attention. Your start-up will also be smooth and easy, with minimal training for your operations and maintenance personnel. The major components (pumps and blowers), as well as the monitoring and testing devices should already be familiar to them. You may even specify the automation level you prefer - manual, PLC, RTU/PC, SCADA, or any number of other systems.
