Tri-Oval Oxidation Ditch System

The Tri-Oval Oxidation Ditch System, named for our Triton Aerator in an oxidation oval, is a subsurface complete mix, looped reactor system that is ideal for municipal and industrial wastewater treatment facilities. Improved reliability, efficiency, safety, and process control are all hallmarks of the Tri-Oval compared to traditional oxidation ditch aeration technologies. Perfect as well for modernizations of existing infrastructure and retrofits, the energy-efficient Triton TR Series process aerator/mixer, combined with an optimized control strategy, allows for operation at depths as low as 4ft (1.2m) and up to 33ft (10m).

Product Overview

The Newterra Tri-Oval® Oxidation Ditch offers an advanced solution for biological nutrient removal in municipal and industrial wastewater treatment. Its unique oval design and state-of-the-art aeration system ensure efficient process flow and effective nitrification and denitrification, essential for compliance with strict effluent regulations. This compact and scalable system is engineered to meet the demanding requirements of modern wastewater management, providing a reliable and sustainable solution for professionals in the field.

Features

  • Full biological nutrient removal (BOD, Nitrogen, Phosphorus)
  • No aerosols or splashing
  • Complete mixing throughout the water column, eliminating solids settling
  • Additional equipment can be provided to create a system package including controls, instrumentation, secondary clarifiers, and RAS/WAS pumps, and/or an aerobic digester

Benefits

  • Independent aeration and mixing with one piece of equipment for biological nutrient removal
  • Simple, flexible operation with easy process control
  • Reduced power consumption with low cost of ownership
  • Minimal heat loss offers improved winter performance
  • Total reliability, quiet operation, and flexible design for restricted land requirements
