Description	Water treatment implies treating water to the quality level desired by the end user. Water purification generally means making water free from any kind of impurity, such as microorganisms, inorganic and organic contaminants, suspended particles, undesirable dissolved salts, etc. The quality of water is assessed by monitoring physical, chemical, biological and radiological parameters. Carbonates of calcium, magnesium and sodium add to the alkalinity in water, whereas calcium and magnesium are the major contributors of hardness to water. Salinity is total dissolved solids in water such as carbonates, sulphates, nitrates and chlorides of calcium, magnesium and sodium. Thus, water purification may be a single or multi-step process. The steps depend on the kind of impurities present in the water. The purification method may vary depending on the type and quality of raw water. Water treatment and purification methods may be physical or chemical, or a combination. This chapter describes common microbiological and inorganic contaminants in water. Conventional water treatments such as sedimentation, coagulation, chemical disinfection, sand filtration etc., are discussed, together with ceramic filtration, colloidal silver-based filtration, ion exchange etc. Industrial water treatment and case studies of different types of industries are presented.
