Water treatment [SEP] Processes
Two of the main processes of industrial water treatment are "boiler water treatment" and "cooling water treatment". A large amount of proper water treatment can lead to the reaction of solids and bacteria within pipe work and boiler housing. Steam boilers can suffer from scale or corrosion when left untreated. Scale deposits can lead to weak and dangerous machinery, while additional fuel is required to heat the same level of water because of the rise in thermal resistance. Poor quality dirty water can become a breeding ground for bacteria such as "Legionella" causing a risk to public health. Corrosion in low pressure boilers can be caused by dissolved oxygen, acidity and excessive alkalinity.
