Initial aerobic treatment, however, did not lead to any significant change in colour.

One proposal aims at a direct aerobic treatment of the waste.

Aerobic treatment for effluent polishing is also practised at some facilities.

The first stage of treatment is the thermophilic aerobic treatment reactor.

Reviewed aerobic treatment technology focuses on activated sludge with nitrification-denitrification.

Further options include aerobic treatment and sand filtration.

A storage dam would contain treated water that has undergone full aerobic treatment to purify it.

Aerobic treatment of the Preheat wastewater was shown to be feasible with regard to organic carbon removal.

A transitional zone in which the interface between the anaerobic and aerobic treatment zones fluctuates may also be present.

Unlike many other biofilters, aerobic treatment systems require a constant supply of electricity to drive the air pump increasing overall system costs.

Anaerobic and aerobic treatment of chlorinated aliphatic compounds.

Aerobic treatment occurs in the upper zone by means of passive air-water interface transfers and photosynthesis.

Aerobic treatment, Final settlement and Sludge storage.

Maintaining BOD5at the levels in recommended in Table 1 will help ensure that aerobic treatment conditions are maintained.

Treatment processes The following sections describe a number of aerobic treatment systems that have been developed to achieve secondary and advanced secondary wastewater quality levels.

AMH Abattoir can generate electricity to power the aerators in the aerobic treatment lagoon.

Unlike the traditional septic system, the aerobic treatment system produces a high quality secondary effluent, which can be sterilized and used for surface irrigation.

Suspended growth systems Suspended growth aerobic treatment plants use a high concentration of bacteria grown in an aerated tank to treat the wastewater.

All effluent disposal systems must be an aerobic treatment unit (ATU) that is capable of nutrient retention/removal.

In combination with aerobic treatment facilities, the technologies can provide in excess of 99% BOD removal and significant nitrification-denitrification.

Aerobic treatment is so effective at reducing odors, that it is the preferred method for reducing odor from manure produced by farms.

By using the biogas for electricity to run the aerators in their aerobic treatment pond, the project could be expected to pay for itself in four years.

In addition, aerobic treatment facilities provide treatment of condensate during the campaign and treatment of anaerobic effluent following the campaign.

His research involves studying the effects of temperature transient conditions on the aerobic treatment wastewater, with emphasis on treatment performance, solids discharge, and microbial response.
