Understanding Wastewater Biological Treatment – A Key Step Toward Cleaner Water

The treatment of wastewater is one of the basic and environmentally friendly processes of the wastewater biological treatment area. In this process organic matter and pollutants contained in the wastewater are broken down by the help of the microorganisms. It is essential in the treatment of both municipal and industrial effluence yet results in cleaner and safer disposal of water to the environment.

Biological treatments come in two forms; aerobic and anaerobic. Oxygen is introduced during aerobic treatment in order to proliferate the growth of the useful bacteria that feed off the organic waste. This is usually applied in the activated sludge process. In Anaerobic treatment lack of oxygen promotes the growth of various microorganisms to decompose waste and in most cases this results in the production of biogas as a byproduct.

A very critical factor that aids with this biological process is the wa
