The bacteria run out of food and die off naturally.

|
|
They die due to a lack of oxygen.

Detailed explanation-1: -Wastewater entering a treatment plant is aerated to provide oxygen to bacteria that degrade organic material and pollutants. Microbes consume the organic contaminants and bind the less soluble fractions, which can then be filtered off. Toxic ammonia is reduced to nitrogen gas and released into the atmosphere.
Detailed explanation-2: -Bioremediation is the use of living microorganisms to degrade environmental pollutants or to prevent pollution. In other words it is a technology for removing pollutants from the environment thus restoring the original natural surroundings and preventing further pollution.
Detailed explanation-3: -Bioremediation is the use of microbes to clean up contaminated soil and groundwater. Microbes are very small organisms, such as bacteria, that live naturally in the environment. Bioremediation stimulates the growth of certain microbes that use contaminants as a source of food and energy.
Detailed explanation-4: -It is a natural process; it takes a little time, as an adequate waste treatment process for contaminated material such as soil. Microbes able to degrade the contaminant, the biodegradative populations become reduced. The treatment products are commonly harmless including cell biomass, water and carbon dioxide.
