In several industrial applications, the occurence of silica in the used waters is undesirable. Many studies show the complexity and the diversity of the topic. For a better understanding of the problem encountered in water treatment, particularly in water desalination, a synthesis of the different analytical aspects of silica are presented. A diagram summing up the evolution of the different forms of silica (dissolved, polymerized and colloïdal) as well as the terminology associated to its determination is proposed. The different approaches and processes of silica removal, in aqueous electrolyte solutions, are reviewed.
