Water Treatment Plants


Water Treatment Plants

Public Water Systems (PWSs) come in all shapes and sizes, and no two are exactly the same. They may be publicly or privately owned and maintained. While their design may vary, they all share the same goal: providing safe, reliable drinking water to the communities they serve. To do this, most water systems must treat their water. The types of treatment provided by a specific PWS vary depending on the size of the system, whether they use ground water or surface water, and the quality of the source water.
The amount and type of treatment applied by a PWS varies with the source type and quality. Many ground water systems can satisfy all standard requirements without applying any treatment, while others need t o add chlorine or additional treatment. Iran Water Planning Bureau is developing a ground water rule that will specify the appropriate use of disinfection and will address other components of ground water systems to assure public health protection. Because surface water systems are exposed to direct wet weather runoff and to the atmosphere and are therefore more easily contaminated, national and state regulations require that these systems treat their water. Disinfection of drinking water is one of the major public health advances of the 20th century. However, the disinfectants themselves can react with naturally occurring materials in the water to form unintended by products which may pose health risks. A major challenge for water suppliers is balancing the risks from microbial pathogens and disinfection by products. Water suppliers use a variety of treatment processes t o remove contaminants from drinking water. These individual processes may be arranged in a “treatment train” (a series of processes applied in sequence). Drinking water standards apply to water systems differently based on their type and size. Most residences including homes, apartments, and condominiums in cities, small towns, and mobile home parks are served by Community Water Systems.
The most commonly used processes include filtration, flocculation and sedimentation, and disinfection for surface water. Some treatment trains also include ion exchange and adsorption. Water utilities select a combination of treatment processes most appropriate to treat the contaminants found in the raw water used by the system.
