Oxidation Ditch Technologies

Oxidation Ditch Technologies

Kruger is a leading supplier of Oxidation Ditch technologies and offers some of the most advanced treatment processes on the market today.

Kruger's activated sludge processes can be adapted to a wide range of treatment requirements from basic secondary treatment to advanced nutrient removal. In addition, Kruger has the capability to upgrade or retrofit existing systems.

We offer the following biological wastewater treatment systems:

A Phased Isolation Ditch system is a continuous flow activated sludge process in which the main treatment phases of the process are isolated into separate oxidation ditches. The process conditions within the oxidation ditches will alternate or phase between oxic, anoxic and/or settling. Phased Isolation Ditch can be designed to operate with or without external clarifiers. These processes include the Double Ditch (D-Ditch), Triple Ditch (T-Ditch), BioDenitro and BioDenipho.

Double Ditch/Triple Ditch

The D-Ditch and T-Ditch technologies consistently produce a fully nitrified effluent, low in BOD and suspended solids, without the use of clarifiers; in addition, the T-Ditch is capable of denitrification.

BioDenitro/BioDenipho

The BioDenitro and BioDenipho processes provide a flexible means for advanced nutrient removal without the need for separate anoxic tankage or internal recycle pumps. The BioDenipho process also incorporates a state of the art Block and Hong anaerobic selector for biological phosphorus removal.

A/O®, A2/O, An/O

Kruger also offers other advanced treatment processes, such as Anaerobic/Oxic (A/O®), Anaerobic/Anoxic/Oxic (A2/O), and Anoxic/Oxic (An/O) that can be adapted to both oxidation ditch and conventional activated sludge plants.
