Answer 2

Activated sludge process.
In an activated sludge wastewater treatment process, microorganisms (bacteria, fungi, and protozoa) are cultivated in a basin. These organisms need organic material to feed on. Domestic wastewater, or sewage, is loaded with organic material, but it is difficult to settle it out of the water to remove it. In the activated sludge process, wastewater is introduced into the basin with the activated sludge, and the microorganisms consume the organic matter in the wastewater. The microorganisms convert the organic matter in the wastewater into a form that settles out of the water more easily.

Answer 3

A simple answer... Biological wastewater treatment is a sewage works. The process relies on microbe action to break down the organic waste into less harmful effluents and residues. This is called biodegradation.

Answer 4

Bacteria called methanogens can convert some of the chemical compunds in wastewater to methane, which then escapes (it is a gas). The special bacteria are members of the group called archeaebacteria.

Answer 5

That is the process of breaking down waste water (like from the toilet) using bacteria. The water sit in holding tanks with the bacteria in it. The bacteria breaks down the waste by feeding on it. The water is then further treated chemically.
