M-TAD™
Process
Cost-effective Anaerobic
to Aerobic Transitions
Introducing a revolutionary aerobic digestion process with a seamless, cost-effective, space-saving system: the Mechanically Thickened Aerobic Digestion (M-TAD) process.
This innovative system enhances pathogen destruction, reduces solids retention time, and improves pH and temperature control. It can convert anaerobic digesters to aerobic digesters without extensive modifications, making it an ideal choice for municipalities and industries seeking to enhance sludge management operations while minimizing their digestion footprint.
THE PROBLEM
Biosolids management is a challenging task for municipal wastewater treatment plants. Every day, 16,000 U.S. facilities treat about 34 billion gallons of wastewater. Traditional methods of transitioning from anaerobic to aerobic digestion are expensive–between 30% and 60% of plant operating and maintenance expenses–with large sludge volumes for disposal and inadequate pH and temperature control.
THE OVIVO SOLUTION
M-TAD™ offers a cost-effective and efficient solution for transitioning to aerobic digestion while minimizing digestion footprint.
This patented, non-clog, single-drop diffuser system maintains the original digester structure while improving aerobic digestion efficiency.
Through mechanically thickening devices such as gravity belt and rotary drum thickeners, the M-TAD™ system manages high-viscosity sludges up to 4%.
By combining sludge thickening and controlled aerobic digestion into one operation, it vastly improves a plant’s ability to efficiently manage biosolids while reducing daily operating and maintenance costs.
The M-TAD™ system’s design also allows existing digesters to retain their cone bottoms, reducing construction costs and adding process volume. And it’s all backed by Ovivo’s Class B biosolids guarantee, ensuring reliable performance and compliance.
All this makes the M-TAD™ system a smart choice for municipalities and industries.
HOW IT WORKS
The M-TAD™ aerobic digestion system consists of a mechanical thickening device feeding pre-thickened sludge at 3% to 4% total solids concentration to two or more aerobic digester basins that operate in either series or parallel mode. (A typical waste-activated sludge feed digester operates in series mode.)
Multiple digesters provide pathogen destruction and volatile solids reduction. When thickened sludge is fed to the aerobic digester, as much as 80% of the total oxygen requirement is in the first digester.
The second digester handles the remaining volatile solids and pathogen reduction.
Most of the digestion takes place in the first digester. This phase requires the most oxygen and handles most of the volatile solids reduction.
