Before raw water is desalinated, the undesirable materials will be removed or reduced to acceptable levels. Such materials to be removed include solids, immiscible liquids, and sparingly soluble salts. Accumulations of these materials on desalination process surfaces greatly reduce efficiencies. Without adequate pretreatment, desalination facilities are destined for reduced lifetimes, shortened periods of operation, and high maintenance. Course Outline 1. SITE SELECTION 2. WATER SOURCE SELECTION 3. GENERAL PROCESS SELECTION 4. PRETREATMENT CONSIDERATIONS This is an introduction to the materials and methods recommended for pretreatment of source water for water desalination processes.
