Modern Water Desalination Technologies

Details :

Water desalination technologies play a crucial role in socio-economic development in a number of countries in the world. Desalinated water is an essential and often the sole, source of fresh water in several of these countries, and rising living standards and high population growth are likely to render desalination a viable option for many areas of the world. Fresh water is rapidly becoming a scarce resource in many countries around the world. Modern desalination technologies, applied to seawater and brackish water, offer effective alternatives in a variety of circumstances. For some countries in the world particularly in Gulf States they are on the most aird part of the globe and characterized by some of the world's highest population growth rates, would benefit greatly from the adaptation, further development and wider dissemination of desalination technologies.

Large-scale thermal desalination technologies have been in use since the 1950s. The larger desalination plants have provided fresh water supplies for drinking municipal use and agricultural development, particularly in the Gulf States. In the past, high capital costs and heavy energy consumption generally translated into excessive desalinated water costs. However, advances in technology have helped to drastically reduce capital and running costs as well as energy requirements, rendering desalination more viable an option than ever before.

This course is essentially aimed at outlining trends in modern desalination technologies and highlighting the options offered by recent technological advances. The seminar covers available technologies, proposed design improvements and market potential in the near future. Through case studies, some of their more salient features are examined. Energy demands for both current processes and the newer innovations will be discussed. The seminar will cover both major processes in water desalination, the thermal and the membrane separation.

Upon successful completion of this course, the delegates will be able to:

ü Apply and gain a basic understanding of Thermal Desalination Processes

ü Perform the role of Membrane Separation Processes

ü Use the basic concepts of Desalination Economics

ü Understand the Strategic Issues In Desalination Technology Capacity Building

ü Analyze and Understand the Renewable Energy Desalination Technologies

ü Use the Recent Trends and Expected Future Developments in Water

ü Use the basic concepts of Desalination Technologies

ü Wastewater Collection Pumping Systems

This course is aimed for engineers, scientists and technologists involved in the planning, management and operation of water desalination systems and also for manufacturers, consultants, designers, researchers and water personnel. This course is also suitable for water laboratory staff including lab managers, chemists, scientists, analysts, technologists and other lab technical staff.
