Sewage Waste.

Bioremediation of various waste waters is a new technology that has undergone a lot of deep investigation in recent decades. With growing population, advanced agricultural practices, industrialization, urbanization and multiple use of water has increased the demand for water around the globe. Due to daily human activity and also various agricultural and industrial operations, wastewater is produced in huge quantity. Due to lack of proper management and treatment facilities most of the urban wastewater generated in Indian cities is discharged into natural aquatic environments without any proper treatment. Municipal sewage problems are more complex as the volume of the wastewater is large and it also requires large area for treatment. Several techniques have been recommended for effective wastewater treatment but among all of them bioremediation is the most effective management tool to control the environmental pollution and to improve the contaminated sites.
