OUTLINE
11.1 INTRODUCTION
As indicated in Chapter 2, saline source water contains five key types of foulants that depending on their concentration could have a significant impact on desalination plant oper- ations: (1) particulate, (2) colloidal, (3) mineral, (4) natural organic matter, and (5) microbial. The purpose of pretreatment is to reduce the content of all types of foulants contained in the
