Picture depicts one of the two oxidation ditch modules.

Above this cost, oxidation ditches become the cheapest option.

Oxidation ditches are high efficiency robust units usually used in carousel type reactors.

As indicated below, oxidation ditch systems are installed worldwide, often in close proximity to residential and commercial premises.

Investigation into the options available for wastewater treatment required during the bypass and upgrading of an oxidation ditch plant.

The highest effluent concentrations were found in oxidation ditch and trickling filter treatment plants.

As indicated below, oxidation ditch systems are installed worldwide, with significant reduction in land space requirements, often allowing expansion of industrial activities.

In 1980, an oxidation ditch of the Carousel variant was constructed to cope with increased domestic and trade waste flows.

They include oxidation ditches, aerated lagoons, and stabilization ponds.

This will replace an existing oxidation ditch which is emitting effluent quality above regulatory levels and threatening the municipal water supply.

Organic NPRI substances are expected to decompose in an oxidation ditch.

Nonylphenol is an NPRI substance which can be formed in an oxidation ditch.

Oxidation Ditch Industrial Wastewater Treatment benefits include:

These are oxidation ditches, often referred to by manufacturer's trade names such as Pasveer, Orbal, or Carrousel.

Oxidation Ditches (Option) If very strict discharge limits are required, an oxidations ditch can be installed for final treatment before the water is discharged.

Oxidation ditches can be converted to BNR by careful selection of the pumping rate and positioning of the raw influent feed.

Activated Sludge: Oxidation Ditch Volatile NPRI substances can be emitted to air in an oxidation ditch.

Applications Sewage The aeration's and circulation of oxidation ditches, aerobic treatment of sewage effluent, mixing, consolidation and treatment of sludge.

A World Bank study carried out in Sana'a, Yemen, in 1983 makes a detailed economic comparison of waste stabilization ponds, aerated lagoons, oxidation ditches and trickling filters.

Other aerobic treatment technologies (e.g. facultative lagoons, aerated lagoons, trickling filters, rotating biological contactors, oxidation ditches, sequencing batch reactors) could also have merit in specific instances.

The jet oxidation ditch is an example of technology innovation where the combination of a deeper basin design, bottom to top mixing and conservation of momentum combines to make a very efficient treatment process.

DESCRIPTION: Upgrading and expansion of an extended aeration activated sludge treatment plant (oxidation ditch type) serving two federal penitentiaries to a capacity of 442 m3/d.

APPLICATIONS Tuke & Bell high intensity Horizontal Aerators are ideal for conventional aeration, extended aeration and oxidation ditches.

Among the 16 activated sludge plants for which operating data was available for 1989, 9 showed an interesting potential for conversion to biological phosphorus removal (6 with aeration tanks, 1 with oxidation ditches and 2 with sequencing batch reactors).
