  1. CE 370Introduction to Water and Wastewater Treatment Plants

  2. Types of Units • Operations • Sedimentation, filtration, flotation • Processes • Coagulation, GAC adsorption, chlorination, activated sludge

  3. Water Treatment Plants • Common Surface Water Treatment Plants • Filtration • Softening • Chlorination • Common Groundwater Treatment Plants • Softening • Gas striping • Chlorination

  4. Degree of Treatment

  5. Other Parameters that Affect the Selection of the Degree of Treatment • Physical Characteristics • Inorganic Chemicals • Organic Chemicals • Radionuclides • Ease of removal by the selected treatment scheme

  6. Rapid Sand Filtration Plant

  7. Design Parameters • The plant is designed based on the average flow on the day of maximum demand • The clear well, which provides storage, is designed so that the plant may operate at a constant rate on the day of maximum demand
