These plants use the activated sludge technology which requires electricity.

On average, over 96% removal has been found with secondary activated sludge treatment.

The new design included an activated sludge treatment plant that involved higher capital and operating costs.

The plant uses the activated sludge technology and was built in two stages during the 1990s.

Activated sludge technology is the most widely used method for wastewater treatment.

They are the "active" part of activated sludge process.

This leaves a concentrated waste product that is then treated using the activated sludge process.

There are a variety of types of activated sludge plants.

It was isolated from activated sludge of a municipal wastewater treatment plant.

The effluent was treated by an activated sludge process, before discharge to the river.

For example, it is used in the Activated sludge model for sewage treatment.

In 1914, he began the first large-scale investigations of the new sewage treatment process called activated sludge.

The second stage is an activated sludge process.

The secondary clarifier removes the activated sludge from the water.

Some use Imhoff tanks or the activated sludge procedure commonly used in many developed countries.

In this instance, the biosludge itself is the primary host (activated sludge) for the bacteria.

A solution is to construct three wastewater treatment plants with "activated sludge" and "high capacity".

Activated sludge and trickling filters are two of the most common means of secondary treatment.

Activated sludge models are used in scientific research to study biological processes in hypothetical systems.

The result is a system which offers significant cost reduction compared to activated sludge and granular carbon treatment options.

Further treatment is typically a modified form of activated sludge to substantially reduce the dissolved organic content.

Extended aeration is a method of sewage treatment using modified activated sludge procedures.

This, as with activated sludge process then goes into a secondary sedimentation tank, to remove the organic matter from the stones.

ASM1 therefore catalysed the research and had a major impact on activated sludge modelling .

Activated sludge biotreaters (Secondary treatment; also used for industrial wastewater)
