Desalination of Sea Water

Description:

Of the more than 7,500 desalination plants in operation worldwide, 60% are located in the Middle East. The world's largest plant in Saudi Arabia produces 128 MGD of desalted water. In contrast, 12% of the world's capacity is produced in the Americas, with most of the plants located in the Caribbean and Florida.

Desalination is a process that removes dissolved minerals (including but not limited to salt) from seawater, brackish water, or treated wastewater. A number of technologies have been developed for desalination, including reverse osmosis (RO), distillation, electrodialysis, and vacuum freezing. Two of these technologies, RO and distillation, are being considered by municipalities, water districts, and private companies for development of seawater desalination in California. This course describes these methods of desalination and all topics related to desalination systems.

Goal:

To enhance the participant’s Knowledge, Abilities and Skills necessary to be updated with the desalination plants like, MSF (multi-stage flash distillation). RO (reverse osmosis), MED (multi-effect distillation), and to regenerate the skills of participant, and to stand on the most modern technologies and the common problems facing the operation process of these systems and method of treatment of product water.

Objectives:

By the end of the course the participant will be able to:

  • Discus the main principles desalination processes like MSF, MED, and RO

  • Improve his technical behavior in operation processes of desalination.

  • Develop the instruments required for analysis.

  • Explain the basic theories of desalination processes, like MSF, MED, and RO.

  • Explain the pretreatment systems of the desalination processes and treatment of product water. Use of computer and software in desalination processes.

  • Be updated with the most resent methods of analysis of sea water, product water, and all types water
