Treatment of Domestic Waste Water by Using ABR and Duckweed Pond

K. Sunil Prakash

Abstract


Population growth and climatic instability are putting increasing pressure on water resources, and promoting increased interest in the treatment of domestic wastewater as an alternate source. Water is the basic necessity for the existence of human society. Water has been recognized as the cardinal element of nature and has been worshipped as the life giving and life sustaining medium in ancient and modern religions of the world. Tamil Nadu is one of the water starving states of India, where the exterior water potential has been fully tapped .Now-a-days there is an increasing pressure on ground water exploitation. Without proper planning Superfluous generalization of water for domestic, industrial supply and agricultural area are used and priorities will adversely affect the surface water. Treatment of domestic wastewater reserve special consideration because it is produced in large quantities. In this study the treatment of domestic wastewater was performed in a 15 L ABR as pretreatment and duckweed pond for post treatment can purify the water and this water can be used for agricultural purpose.
