Johnsen Chapter 6 Water and Waste Water ProblemsAvailable online 11 April 2008This chapter provides an introduction to the problems of water and waste water. Reduction of the biological oxygen demand is discussed. When organic matter is added to an aquatic ecosystem it is immediately attacked by bacteria, which break it down to simpler substances, using up oxygen in the process. The rate of which a particular type of effluent is able, in the presence of ample oxygen, to satisfy its oxygen demand depends on what it contains. Industrial effluents, which contain only chemical reducing agents, such as ferrous salts and sulfides, take up oxygen purely by chemical reactions.

They do this very rapidly, exerting what is called immediate oxygen demand. Organic substances, such as carbohydrates and proteins, become oxidized by the activities of bacteria. The rate at which they are broken down therefore depends first on the presence of suitable bacteria and second on how satisfactory and balanced a food they are for microorganisms.Copyright © 1989 Published by Elsevier B.V.
