The pollution of our water resources is mainly due to the discharge of waste mainly produced by anthropogenic sources such as industrial purpose, agricultural waste and household and untreated wastewater. The need of the hour is to have a treatment for the waste water. Wastewater treatment is a process which is used to convert wastewater (highly polluted water) into an effluent that can either return to the water cycle with minimal environmental issues or reused safely. The different stages of treatment are preliminary, primary, secondary, and tertiary or advanced treatment. In secondary treatment, biological treatment is more cost-effective than chemical treatment. Biological treatment of waste water reduces the concentration of pollutant through microbial action and removal of non-settle able organic colloidal solids. There are various technologies used in the treatment of wastewater in the present times. The best technology can be selected for a particular place based on various parameters like area requirement, initial, operation and maintenance cost, power requirement, quantity as well as quality sludge produced etc. The paper aims to establish comparative analysis of three popular wastewater treatment techniques. The main technologies studied are as: (1) Sequencing Batch Reactor (SBR), (2) Rotating Biological Contractor (RBC), and (3) Soil Bio Technology (SBT).
