Water treatment in its broadest context can be defined as the subjection of water to an agent or process with the objective the source quality to meet application-specific criteria or standards. Water treatment has been a concern of all human settlements since earliest times. Prior to the industrial revolution, water treatment evolved based on empirical observations without a scientifically based understanding of the underlying mechanisms of treatment processes. In the public sector, the major objective of water treatment up to the 20th century, was providing a water of desirable aesthetic quality while at the same time protecting consumers from water born diseases. In the industrial sector, during this time, the primary concern was obtaining water in sufficient quantity and quality to permit expansion of the growing industrial centers.
