Water Treatment
Treating water The quality of water is crucial to the success of a soft drink. Impurities, such as suspended particles, organic matter, and bacteria, may degrade taste and colour. They are generally removed through the traditional process of a series of coagulation, filtration, and chlorination. Coagulation involves mixing a gelatinous precipitate, or floc (ferric sulphate or aluminium sulphate), into the water. The floc absorbs suspended particles, making them larger and more easily trapped by filters.
