Generally refers to wastes discharged into surface waters”. The Compact Oxford English Dictionary defines effluent as “liquid waste or sewage discharged into a river or the sea”.

The article‚ Biotreatment of wastewater using aquatic invertebrates‚ Daphnia magna and Paramecium caudatum‚ mainly pertains to the idea of cleaning dirty‚ polluted water. Every since we‚ as a society‚ have switched from an agrarian to an industrial way of life‚ our waters have become increasingly polluted. Thus‚ scientists have researched conducted experiments in order to attain clean water. One of the failed attempts of attaining clean water was one in which they tried to use chemicals. Unfortunately

Lakes are relatively small to large water bodies surrounded by land on all sides sustaining an ecosystem in and around them. Lakes have been an integral part of the ecological system by providing natural abode for plants‚ animals and microorganisms. Increase in urbanization and industrialization has led to the destruction and in the reduction of lakes in the city of Bangalore‚ Surviving lakes in Bangalore are reduced to cesspools due to direct discharge of industrial effluents and unregulated dumping

Cochabamba in Bolivia is an example of a city that faces increasing environmental problems and health risks due to insufficient sewage system coverage and municipal wastewater treatment. The situation is especially severe in peri-urban fast growing settlements. A decentralized alternative to conventional wastewater treatment plants is constructed wetlands with horizontal subsurface flow (HSF). This treatment method exists in many parts of the world and a few wetlands have been constructed in Cochabamba

water? Wastewater treatment plants: * Remove solids‚ everything from rags and plastics to sand and smaller particles found in wastewater; * Reduce organic matter and pollutants--naturally occurring helpful bacteria and other microorganisms consume organic matter in wastewater and are then separated from the water; and‚ * Restore oxygen--the treatment process ensures that the water put back into our rivers or lakes has enough oxygen to support life. Where does wastewater come from

useful parameters (measured characteristics) indicating the organic strength of a wastewater. BOD measurement permits an estimate of the waste strength in terms of the amount of dissolved oxygen required to break down the wastewater. The specifics of the analysis are discussed in detail in Standard Methods for the Examination of Water and Wastewater. The BOD test is one of the most basic tests used in the wastewater field. It is essentially a measure of the biological and the chemical component
