Water recycling systems implies the initial treatment requirements for various water reuse schemes including unit process descriptions, performance and cost data. Several volumes of text are required for adequate coverage of the above subject and this paper will only attempt to highlight important areas, provide guidelines and give needed direction. Cost functions of one important U.S. Research/ Demonstration Facility (Water Factory 21) are given in more detail. Much of the data has been summarized from four important publications shown below and the reader seeking additional information is encouraged to examine these in detail.
