Reducing Biosolids Management Costs by optimising aerobic digestion

M-TAD Process

The Mechanical Thickened Aerobic Digestion (M-TAD™) process is a controlled aerobic process engineered and designed to meet Class B stabilisation requirements by integrating system optimisation techniques and making use of a unique non-clog single drop diffuser system.

The M-TAD™ process utilises a mechanical thickener to thicken solids up to 4% which significantly reduces aerobic digestion volume and footprint. This process can also be retrofitted into existing tanks.

With more than 30 billion gallons of wastewater being treated in 16,000 facilities every day in the United States, biosolids management is a serious issue in municipal wastewater treatment. It is responsible for between 30 and 60 percent of operating and maintenance expenses.

Ovivo’s M-TAD™ process solution is ideal for both new plants and existing plants looking to retrofit. These systems also allow plants to maintain the industry standard of using solids in land applications instead of just disposing to landfills.

Expand your system’s ability with minimal cost and effort

Ovivo’s M-TAD™ process combine sludge thickening and controlled aerobic digestion into one seamless operation, dramatically improving your plants treatment ability to efficiently manage biosolids while reducing daily operating and maintenance costs. The features and benefits of these solutions include:

  • Class B biosolids stabilisation
  • Minimised footprint
  • Ideal for converting anaerobic to aerobic digestion process
  • Easy Retrofit technology
  • Minimal nutrients returned to the upstream liquid treatment process
  • Reduced operating and disposal costs
